sharks

oh well, karena Alexia udh cerita banyak soal 'baby'nya, the tigers, gw jadi pengen buat tret soal hiu, my baby

gw jatuh cinta sama hiu sejak umur 3 tahun, nonton Jaws di bioskop. takut, tapi penasaran. dicekoki buku2, nonton kumpulan video soal mereka -and thanks Mr. Jaques Coestau-, then years after, i knew i was fallin in love to these beautiful monsters.



origins

sharks and common fishes started the evolution over 400 million years ago. disini, ikan bertulang sejati(Osteichytes) dan ikan bertulang rawan (Chondriochytes) berpisah. Hiu, pari,adalah golongan yg bertulang rawan, karena itu, fosilnya susah ditemukan kecuali yang berasal dari masa 'perpecahan' di zaman Paleozoic.


hiu, tidak berevolusi sejak 35 juta tahun terakhir

evolusi terakhir mereka berlangsung sekitar 100 juta tahun yg lalu, di zaman Cretaceous, dimana pada waktu itu lebih banyak hiu air tawar daripada hiu yg hidup di laut seperti sekarang.

and you know what? back then, they were bigger!

leluhur Charcarodon charcarias (great white shark), Charcarocles megalodon, was the biggest shark that ever existed in the planet. hidup di jaman Pliocene (18 juta tahun yg lalu), dan hilang di era Miocene (5 juta tahun yg lalu)

look at the size, Charcarocles megalodon kalo hidup di jaman sekarang, berenang di dket kita:






fosil gigi si Megalodon


can you imagine how big it was??


dan yah, i LOVE them, because they're perfect!

hiu adalah predator laut paling sukses, terbukti karena mereka tidak berevolusi sesering dan sebanyak spesies lainnya. hal ini udah cukup membuktikan bahwa mereka sempurna.


the killing tools

dan kenapa mereka bisa survive selama itu tanpa berevolusi?




mereka punya 7 indra


~the eye



hiu bisa melihat jelas mangsanya sampai jarak 50 meter kedepan. semakin dalam air, warna akan diserap semakin jelas oleh mata hiu seiring bertambahnya kedalaman air. even better, sharks have night vision better than cats family or any other predator becos their eyes can amplify the contrast and brightness of their surroundings .talking about living photoshop tools...

~ the nose
penciuman hiu 10.000 kali lipat penciuman manusia.mereka hanya butuh setetes darah untuk diendus dalam sekitar 5000 galon air laut ..dan begitu darah terendus..

~the taste
oh ya, hiu pilih2 makanan juga..(kecuali bullsharks, they eat anything, include boots, life jacket, license plates and all ) .

~electrosense


Kutipan:
Probably the most fascinating sensory performance of sharks is their ability to detect electrical fields. All living things emit electrical fields, either with the beat of the heart, muscle movement or with the brain. Animal prey can effectively hide or camouflage themselves, but they cannot conceal their electrical fields.
The shark's electrosensor are its Lorenzini ampoules. Only sharks or rays have them. They consist of the ampoule and a long canal filled with a jelly-like substance which ends in a pore. Hundreds of such pore groups are located on the shark's head, especially in the region of their snout. Since the electrical impulses of prey animals are very weak, the electrosensors only function within a range of several centimeter
can you run from it?

dan ya, ini juga alasannya kenapa banyak konvoi hammerhead sharks di kepulauan macam hawaii, barbados, karibia, dan filipina. these islands are volcanic islands.volcanic islands ~ ada jalur lava dibawah dasar laut ~ medan magnet ~ peta navigasi ikan.
hammerhead sharks punya ampula Lorenzini lebih banyak, karena itu mereka jadi tertarik ngikuti peta magnetik ini untuk terus jalan2 dan makan.


~ the ear



Kutipan:
Sound travels under water about four times faster than on land, whereby low frequencies dissipate slower than high ones. The sense of hearing is thus important to sharks. They react especially to low frequency, pulsating oscillations around 100 Hz, as produced by sick or wounded animals. Several shark species can thus accurately locate their prey over a distance of several hundred meters.
ini juga alasannya untuk jangan teriak2 panik didalem air laut kalo kecebur tiba2 ato kram..

~ Sense of touch

Kutipan:
Shark skin has highly sensitive pressure and temperature sensors, some of which are so sensitive that they can register skin vibrations/movements of only 0.02mm. With these sensors sharks can feel contacts, water currents and temperature changes.
~Pressure sensors

Kutipan:
Lateral line
The lateral line system of sharks extends from the head to the caudal fin. It contains sensory cells embedded in jelly and is connected to the skin surface by small pores. The jelly conducts shock waves to the sensory cells.

Pit Organ
The pit organ consists of two oversized denticles which cover a small pocket in the skin. At the bottom of this pocket is a collection of sensory hair cells. Many sharks have these pit organs in greater numbers on their backs, sides and lower jaw. The exact function of the pit organ has not yet been determined, but most likely sharks use it to register mechanical stimuli such as water currents.

and. when all the tools work together...it will be like this:

size

the cutest

Spined Pygmy sharks (Squaliolus laticaudus).

panjang maksimumnya 25cm.yg paling kecil diantara keluarga hiu.



mereka punya zat luminescent di bagian perutnya.spesies langka, atau jarang ketemu manusia, entahlah. habitat mereka: tinggal di perairan yg berkedalaman 2000 meter, tapi berburu di malam hari di kedalaman 600 m. biar kecil, mereka punya gigi silet untuk berburu makanan kesukaannya: cumi dan udang kecil.


the giant one

Whale shark (Rhinocodon typus)

yes, the biggest fish on the planet is a shark.



si cantik ini lebar mulutnya 1,4meter. panjangnya 14 meter minimal, dan berat minimalnya 15 ton. mereka dewasa di umur 30 tahun, dan di saat itulah mereka baru bisa matang secara seksual dan siap bereproduksi. This beautiful creature is a solitary soul. Mereka berenang sendirian, kebanyakan di permukaan air untuk makan plankton, krill, udang2 kecil. karena mereka besar, mereka butuh makan banyak. dengan 3000 gigi penyaring, mereka menyaring 6000 liter air per jam untuk dapetin plankton makanannya.

Whale sharks berkembang biak secara vivipar, telurnya lonjong, ukurannya 36 cm. telur terbesar di dunia.

whale sharks bisa hidup sampe umur 150 tahun

to be continued

streamline power

hiu punya bentuk badan yang streamline sempurna, membuat mereka bergerak dengan bebas dan mudah di dalam air.


si perenang cepat, shortfin mako shark (Isurus oxyrinchus), bisa berenang sampai kecepatan 50mph atau 80 kph. bandingkan dengan manusia (as in, Michael Phelps) yang kecepatan berenangnya hanya 5 mph. can you escape a shark?

tapi, rahasia dibalik kecepatan berenang hiu bukan hanya ada di bentuk tubuhnya yang streamline, tapi kulitnya. kulit hiu nggak bersisik. sepintas kelihatannya halus tapi kesat. samurai menggunakan kulit hiu sebagai pelapis gagang pedang supaya pedang bisa digenggam dengan nyaman dan nggak gampang jatuh ato pegangan jadi selip.
why?

it's because their skin are actually micro-sized teeth. seluruh tubuh mereka dilapisi gigi - gigi kecil yg namanya dermal denticle alias 'kulit gigi'

ribuan gigi - gigi kecil ini bisa dinaik-turunkan oleh si hiu, tergantung mereka mau berenang santai ato berenang mengejar mangsa. aliran air akan melalui sela - sela gigi kecil ini, mengurangi benturan dan gesekan tubuh dengan air, yang membuat mereka bisa berenang sangat cepat.

berenang santai:


berenang cepat:



deadly bite

Kutipan:
The teeth of sharks are not attached to the jaw, but embedded in the flesh, and in many species are constantly replaced throughout the shark's life. When they lose a working tooth it will be replaced by the next tooth behind it. All sharks have multiple rows of teeth along the edges of their upper and lower jaws. New teeth grow continuously in a groove just inside the mouth and move forward from inside the mouth on a "conveyor belt" formed by the skin in which they are anchored. Typically a shark has two to three working rows of teeth with 20 to 30 teeth in each row, e.g. a whale shark has about 300 teeth in each row.[2] The replacement rate has not been measured in most sharks but normally the teeth seem to be replaced every two weeks. The lemon shark replaces its teeth every 8–10 days, and the great white shark replaces its teeth about every 100 days for young sharks and about every 230 days for old sharks.[3] Most sharks shed individual teeth, but e.g. the cookiecutter shark sheds the whole lower jaw at once. The lower teeth are primarily used for holding prey, while the upper ones are used for cutting into it. The teeth range from thin, needle-like teeth for gripping fish to large, flat teeth adapted for crushing shellfish.

Shark teeth are formed by the same mechanism as the scales on sharks' skin
Kutipan:
Sharks and rays both have a polyphyodont dentition, in which old teeth are shed continually throughout the fish's lifetime, and new ones are rotated into place on a conveyer belt-like structure.[1] Shark teeth develop along the inner surface of the jaw cartilage, and are attached to the dental membrane. When the tooth forms in the gum tissue, the crown cap develops first, followed by the root.[1]

Shark teeth are commonly found fossils for two reasons. Sharks continually shed their teeth, and some Carchariniformes can shed approximately 35,000 teeth in a lifetime. Secondly, the environment in which the teeth are deposited after falling from a shark's jaws has a high concentration of phosphate.
jadi, mereka nggak pernah ompong. gigi tanggal satu, barisan gigi dibelakangnya akan otomatis maju kedepan menggantikan yang tanggal, dalam waktu 24 jam.

dan deretan gigi yg ada di dalam mulut hiu:

buoyance

hiu akan tenggelam kalo mereka nggak bergerak.
hiu yang tinggal di area pelagic (0-650feet) dibawah permukaan air, berbeda dengan hiu yang tinggal di area benthic (dekat dasar laut).

beda dengan ikan yang mengapung ato bergerak dengan menggunakan gelembung2 renang, hiu nggak punya gelembung renang, tapi mengandalkan hati/livernya yg sangat besar untuk mengapung. liver hiu terdiri dari 2 bagian besar yang menyimpan asam lemak dan minyak. liver hiu besarnya mengisi 90% rongga tubuh, dan beratnya mencapai 25% dari berat total. jadi pelampung minyak ini menjaga hiu agar tetap mengapung saat dia berenang santai.

minyak hati hiu kaya akan alkylglycerols, squalamine, dan squalene yang bisa menyembuhkan berbagai penyakit, terutama kanker. meskipun masih diperdebatkan karena tiap 3 detik seekor hiu mati diseluruh dunia, minyak hati hiu dan kartilagonya (tulang rawan) menunjukkan hasil positif untuk digunakan sebagai obat kanker dimasa depan. minyak hati hiu -terutama hiu yg hidup di lautan dalam- punya kandungan antioksidan tinggi karena makin dalam laut, makin tipis oksigennya. hiu lautan dalam bisa hidup di kondisi seperti ini, bahkan tidak menua. still a mystery though.




hiu harus tetap berenang untuk hidup, kalo tidak, mereka akan kekurangan oksigen dan mati. nah, gimana kalo capek? beda dengan manusia yang semua kegiatannya diatur otak, pada saat lelah, hiu bisa 'mematikan' otak, dan berenang otomatis ^^

...fakta2 ini bikin gw makin takut liat hiu. Kayaknya tiap kali di pelem nongol ikan hiu ( bahkan cuma sirip aja) jantung udah deg2an ga karuan.

Lambungnya dari besi kali ya ampe piring, jaket, boots pun dicerna

ngebayangin poonya hiu kayak apa

mating

hiu yang lebih kecil, dewasa secara seksual di usia yg lebih muda dibanding hiu yang lebih besar. angel fish dewasa di umur 3 tahun. sementara hiu paus dewasa umur 30 tahun

hiu berkembangbiak dengan cara vivipar dan 30% sisanya berkembangbiak dengan ovipar. telur dibuahi didalam tubuh si betina, dan menetas didalam tubuh betina, baru anak-anak hiu dilahirkan.

dalam memilih pasangan, hiu betina sangat selektif. dia nggak mau asal kawin dengan sembarang jantan
pada musim kawin, hiu akan berenang ke perairan dangkal untuk menemukan jodoh. proses PDKT berlangsung erm..dengan cara..saling mengigit. karena itu, pada musim ini banyak hiu betina dengan bekas gigitan di tubuhnya. kalo si betina gak suka dengan jantan yg pdkt, dia akan balas menggigit, lalu berusaha berontak. kadang, si jantan berhasil memasukkan sperma kedalam tubuh si betina. tapi kalo betinanya gak suka sama jantan ini, dia akan mengeluarkan sperma si jantan tadi, sampai dia ketemu jantan yang dia bener2 suka. kalo dengan jantan yang dia suka, spermanya nggak bakal dikeluarkan.

bayi hiu -gak peduli jenis apa- selalu berbintik2 kyk gini. bintik - bintik akan hilang seiring bertambahnya usia.




hiu yang bertelur akan menempelkan telur yang sudah dibuahi ke tanaman air ato benda lain supaya nggak terhanyut oleh aliran air. karena bentuknya, telur hiu dinamakan 'Mermaid pockets' ato 'dompet putri duyung'


diet
makanan hiu tergantung jenisnya.

hiu yang tinggal di dekat dasar laut kyk Nurse shark ( Ginglymostoma cirratum), makan udang, lobster, kerang :



cara makannya juga unik. pertama, lobster ato kerang besar akan dibanting ke batu2an, baru disedot isinya dengan mulut mereka yg kyk vacuum cleaner.

Hammerhead shark (Sphyrna zygaena), makan ikan dan juga ikan pari.


ada juga hiu yang kanibal, Tiger shark (Odontaspis noronhai) .mereka makan apa saja, sampai sesama hiu.



natural enemy

sejak Megalodon punah, memang hiu tetap jadi top ocean predator. tapi mereka juga punya musuh alami, yaitu Orca/killer whale (Orcinus orca):

http://www.elasmo-research.org/educa.../digestion.htm
Kutipan:
All animals have to have a method of waste excretion. Because sharks do not have separate openings for products of the digestive and reproductive systems, the posterior opening of the gut is referred to as a cloaca instead of as an anus, as in humans. Rather than producing a more-or-less solid bolus of waste matter, as do human anuses (most of the time, anyway), shark cloacae void feces that is generally quite liquidy, typically a dirty mustard brown in color. Sometimes, a streaming cloud of shark feces is punctuated with an unexpectedly pretty surprise: a burst of silvery fish scales, glittering like diamonds in the flickering underwater light. With a graceful swish of its tail, the White Shark dissipates the momentary discoloration, returning its unused energy to the sea.
iya, mereka tetep pup.tapi bentuknya kyk saus mustar gitu

errr... no. ga penting ngebunuhin ikan2 hiu dgn cara penyiksaan cuman buat bikin obat kanker. there are other alternatives. no need for torture and killing of these vulnerable animals. especially when more and more sharks are added to the iucn red list these days.

Iya kenapa nyari obatnya harus dari binatang, dan mending diperlakukan baik.

Kadang gw ngerasa kyk model orang Jepang gitu, memang sih mereka banyak membuat produk ramah lingkungan dsb. Tapi disisi lain, banyak melakukan hal2 yg menyiksa hewan juga, contohnya ya makan sirip hiu. Setengah2 niatnya.

Padahal bikin pelem soal babi, doggy, tp kl melihat kyk gini, jadi meragukan niat mereka Shark kan juga hewan, dan udah langka pula.

sis, gw jg gak setuju sama pembantaian hiu.
counted that setiap 3 detik, seekor hiu mati dibunuh.

i just posted a fact, didnt mean i do agree.

toh gw gak mau pake obat kanker dari hiu. i wont. mereka udah termasuk endangered species. a living fossil, dan gw gak mau ikutan terlibat menikmati kesehatan dari berekor2 hiu mati.

iya.. selalu begini deh.. kalo manusia menganggep suatu hewan ada valuenya, pasti mereka diburu, terus diexploitasi. permasalahannya: exploitation means killing and killing in the human world means torturing.

gue jg mikir yg sama soal org jepang itu. selaen yg lo sebutin di atas, di jepang kan juga banyak ikan yg dihidangin idup2 buat dimakan bingung aja gue ma yg mo makan... ga punya perasaan apa? gue dengernya aja udah ilfil berat

perxepone:
abis lo nge-post fakta tp ga dibarengin dgn fakta laennya bahwa hiu2 ini sering disiksa akibat bagian2 tubuh mereka considered valuable buat manusia itu, jd kesannya kaya promote hiu sbg obat kanker baguslah kalo ternyata ngga begitu

the big family

kebanyakan orang mengira hiu adalah yg seperti ini aja:



padahal, hiu adalah sebuah keluarga besar, atau Class (Chondriochytes) yang terdiri dari 8 Ordo , yaitu:
Dogfish sharks (Squaliformes)
Frilled and cow sharks (Hexanchiformes)
Sawsharks (Pristiophoriformes)
Angelsharks (Squatiniformes)
Bullhead sharks (Heterodontiformes)
Carpetsharks (Orectolobiformes)
Mackerel sharks (Lamniformes)
Ground sharks (Carcharhiniformes)

30 familia, dan lebih dari 500 spesies.

it's really really a big family of hunters, predators, and angels

dogfish sharks

Kutipan:
This order represents the second largest order and includes 7 families and about 113 species and their most distinguishing feature is the lack of an anal fin. Most species also have a spine in front of the first dorsal fin. The majority are deep water species, and some have luminescent organs. Certain species can reach large sizes for instance the greenland shark, Somniosus microcephalus, with 7 m


frilled and cow sharks

Kutipan:
This order is the most ancient one. It consists of 6 species (2 families and 4 genera). The most distinguishable feature is the possession of 6 or even 7 gill slits. This is considered a very primitive feature, as most modern sharks possess only 5 gill slits. Compared to sharks of other orders, frilled and cow sharks only have one dorsal fin.
These sharks have a widespread distribution and live preferably in deeper waters.
The knowledge about their biology is still fragmentary.


sawsharks

Kutipan:
Saw sharks (9 species) are a very unusual group that is often confused with sawfishes, which are rays. The most obvious difference between the two is that saw sharks possess barbels and the teeth, located on the prolonged snout, are different sizes. Only five species are known. One species, the sixgil sawshark (Pliotrema warrani), possesses 6 gill slits and lives on the south-eastern Cape Coast of South Africa.
Not much is known about the general biology of this order.


angel shark

Kutipan:
Like saw sharks, angel sharks are also often misidentified as rays. The most obvious difference is that angel sharks possess pectoral fins that are not attached to or connected with the head. Angel sharks also possess an enlarged caudal lower lobe but, like dogfishes, do not possess anal fins.
This order includes 18 species, most of them of small size. An exception is the japanese angel shark, Squatina japonica, that reaches 2 m.
Unique in angel sharks is that the lower lobe of the tail is longer than the upper lobe.
Angel sharks spend most of the day buried in sand ranging from very shallow water to 1300 m.

bullhead sharks

Kutipan:
The order of the bullhead sharks comprises one family with only one genus. There are only 9 known species of bullhead sharks. These bizarre looking sharks possess strong spines in front of both dorsal fins.
As opposed to the other "spine-wearing" group, the dogfishes, bullhead sharks possess anal fins. As their name implies, their heads look very dominant with big ridges above their eyes, and have a broad snout with very large labial furrows. Based on their heterogeneous teeth (their scientific name "hetero-dontus" stands for different shaped teeth) they are considered as primitive group.
Members of this order live only in the waters of the Pacific and Indian Oceans.
susunan gigi bullhead sharks unik dibanding hiu lainnya

gigi depan:


gigi samping:


ini karena mereka makan lobster dan kerang - kerangan

port jackson shark, salah satu anggota keluarga bullhead shark lucu ya...


carpet shark
mereka dapat nama ini karena emg kulitnya yg bertotol - totol atau bermotif kayak karpet

spesies2 ngetop dari Ordo ini antara lain Whale sharks, Wobbegong,Nurse sharks, dan Zebra sharks. ciri khas dari ordo carpet sharks, mereka punya sungut didekat mulut, dan nggak termasuk kategori hiu yang buas. kecuali Wobbegong. Wobbegong sebetulnya nggak jahat, tapi karena kulitnya yang menyatu sempurna dengan latar belakang dasar laut dangkal yg penuh koral, perenang ato wisatawan seringkali nginjek dia tanpa sengaja. Kalo udah keinjek, Wobbegong otomatis akan gigit sebagai tindakan pertahanan diri. dan, beda dengan hiu lainnya, Wobbegong gak bakal ngelepas gigitannya
'Wobbegong' adalah nama yg diberikan penduduk asli Australia, suku Aborigin pada hiu khas Australia ini. artinya: jenggot jabrik

bayi wobbegong (masih kecil, jadi masih imut2):



wobbegong dewasa (can you see it?):


mackerel sharks

Kutipan:
Mackerel sharks consist of 8 families, 10 genera and 17 species. They are a rather diverse group that lack a singular distinguishing characteristic and for the identification a combination of different features is needed such as: Origin of mouth behind the eyes, conical snout, a pair of 5 gill slits, 2 dorsal fins and no nicitiating membrane. Many of the sharks possess a counter-current circulatory system. This system enables them to maintain a higher body temperature and live in colder waters. Mackerel sharks include the biggest and fastest predators like White Sharks or Makos. Most Mackerel sharks can raise their body temperature by means of a heat exchange system (rete mirabilis).
hiu-hiu populer banyak yang berasal dari ordo ini, macam White sharks, Goblin sharks, Sandtiger sharks, and the fast and furious, the Mako sharks.

mereka ngetop karena..mereka pemburu hebat, serem dan menegaskan image hiu sebagai monster lautan ato Leviatan

Sand tiger shark:


Goblin shark:


Mako shark.
perhatiin mata mereka yang besar.makin besar mata hiu, berarti dia hidup di perairan yang lebih dalam



Basking sharks, satu2nya anggota dari ordo ini yang makan plankton:


basking sharks,er.rada jorok.karena makan plankton, dia sama dengan Whale shark, harus terus terusan menyaring air dari mulut terus ke insangnya. akibatnya, alga sering tumbuh disana. setahun sekali, 'gerigi' di insangnya akan lepas dan diganti yang baru. jadi setahun sekali bersihnya..

the big bad boy
Kutipan:
The family of mackerel sharks consists of 3 genera with 5 species. All of them show several adaptations for fast swimming. This family includes species such as the white and mako shark. All mackerel sharks have a very pointed snout, very dark eyes, relatively large pectoral fins, lunate tails and keels on their peduncles. As other members of the same order this family possesses specially adapted blood circulatory systems that enables these sharks to keep a higher body temperature and therefore higher level of activity. Mackerel sharks prefer cooler waters over the continental shelves and outer slopes and are normally not abundant in tropical waters. These are very active and powerful sharks.
dan, ini dia my lovely baby. Charcarodon charcarias, atau Great white shark. dinamai 'white' karena bagian bawah tubuhnya yang berwarna putih sementara bagian atasnya kelabu. cicit dari Charcarocles megalodon, pembunuh no. 1 di keluarga besar hiu. why i love it? karena, mereka punya personality

ada yg lemah lembut, ada yang srudak sruduk. penyelam2 yg bekerja buat NatGeo dan BBC udh sering ngeliat dalam proses dokumentasi si Cantik ini. ada yang nyamber umpan dengan buas, ada yg pelan - pelan, ditarik pelan2, diendus dulu, deketin yg ngasih, disundul pelan2, baru ngambil umpannya. lucu ya

tapi biar lucu, mereka extremely dangerous to humans. ini murni disebabkan mereka selalu lapar, tertarik pada objek yang bergerak, dan mereka juga makan sesama hiu. termasuk hammerhead sharks bisa jadi makan siangnya mereka kalo sedang iseng, bisa juga loncat ke permukaan, nyari burung ato apapun yang bisa dimakan

mereka termasuk medium, sekitar 5,5 meter - 6,5 meter, beratnya sekitar 2 ton. eh, salah ya, gw bilang medium? er..gede deh
yang betina lebih besar daripada yang jantan. sayangnya, nggak banyak yang diketahui soal si Cantik ini
