[Did you know?] Hiu ternyata bisa jinak gan!

[priatampan]

Pas ane lg mencet2 remot TV, ane ngeliat acara bagus di Animal Planet. Jadi ada penelitian kalo hiu itu bisa jinak kalo daerah sensitif tubuhnya diusap2 . Walopun emg sih masih banyak orang yang menganggap bahwa hiu adalah makhluk paling menyeramkan di lautan.

Berikut infonya gan







Pada suatu hari, ada seseorang yang memiliki bayi2 hiu . Secara tidak sengaja saat ia mengelus2 bagian sisi kepalanya, bayi hiu itu bagaikan terhipnotis dan tidur. Masa tertidur ini dinamakan �Tonic Immobility.� Karena masih diragukan akhirnya ada seseorang ilmuwan yang bernama Michael Rutzen memberanikan diri untuk mencoba Tonic Immobility kepada hiu dewasa. Bahkan diakhir penelitian ia berhasil melakukan Tonic Immobility pada hiu terganas di dunia yaitu hiu putih.

Berikut penjelasan �Tonic Immobility� dari wikipedia :



Tonic immobility is a natural state of paralysis that animals enter, in most cases when presented with a threat. Some scientists relate it to mating in certain animals like the shark.



Some sharks can be placed in a tonic immobility state. The shark remains in this state of paralysis for an average of fifteen minutes before it recovers. Scientists have exploited this phenomenon to study shark behaviour. Orca whales are also known to exploit this in hunting sharks and rays. Usually when testing sharks under this "tonic" state, scientists will put a chemical plume in the water awakening the shark.



Sharks may not always respond to tonic immobility by physical inversion of the animal, as has been demonstrated with lemon and reef sharks. With tiger sharks 3-4 metres (10 to 15 feet) in length, tonic immobility may be achieved by placing hands lightly on the sides of the animal's snout approximate to the general area surrounding its eyes. Great White sharks have been shown to be not as responsive as other species whenever tonic immobility has been attempted. Scientists believe that tonic, displayed by sharks, may be linked with defence, because female sharks seem more responsive than others. During tonic immobility, the dorsal fin(s) straighten, and both breathing and muscle contractions become more steady and relaxed.



Tonic immobility also can be somewhat effective on anole lizards, and a loose study was done with tonic immobility with the rabbit. Both were inconsistent examples of tonic immobility. [citation needed]



Tonic immobility has also been used to describe the paralysis which often immobilizes animals, such as rodents or birds, when they feel threatened by a predator. It can be argued that tonic immobility plays a role in survival if it helps a hunted animal to blend in with its surroundings by remaining as motionless as an inanimate object. This tonic state is common with invertebrates as well.[citation needed]



Inducing tonic immobility in common animals requires, in some cases, extreme treatment such as electric shock, along with other elements which produce stress.[citation needed]

Jadi intinya Tonic Immobility adalah tahap dimana binatang memasuki keadaan lumpuh atau tidur untuk sementara. Kebanyakan alasannya karena binatang itu mengalami ancaman. Salah satunya binatang yang bisa mengalami Tonic Immobility adalah hiu. Hiu akan mengalami Tonic Immobility ketika kedua sisi samping dekat matanya kepalanya dielus-elus. Hampir semua hiu merespon dengan elusan ini, namun terbukti hiu putih adalah jenis hiu yang paling tidak merespon dengan usapan ini. Terbukti juga bahwa hiu betina lebih merespon dibangingkan hiu jantan karena mereka lebih sensitif. Ketika memasuki tahap tonic immobility sirip hiu menjadi tegak, dan otot pernafasan menjadi lebih rileks. Ketika usapan tangan dilepas, hiu itu akan sadar kembali.
