Buaya adalah reptil bertubuh besar yang hidup
di air .Buaya umumnya menghuni habitat perairan tawar seperti sungai, danau,
rawa dan lahan basah lainnya, namun ada pula yang hidup di air payau seperti
buaya muara. Makanan utama buaya adalah hewan-hewan bertulang belakang seperti
bangsa ikan, reptil dan mamalia, kadang-kadang juga memangsa moluska dan
krustasea bergantung pada spesiesnya.
Buaya merupakan hewan purba, yang hanya
sedikit berubah karena evolusi semenjak zaman dinosaurus.Buaya dapat bergerak
dengan sangat cepat pada jarak pendek, bahkan juga di luar air.
Binatang ini memiliki rahang yang sangat kuat,
yang dapat menggigit dengan kekuatan luar biasa, menjadikannya sebagai hewan
dengan kekuatan gigitan yang paling besar. Tekanan gigitan buaya ini tak kurang
dari 5.000 psi (pounds per square inch; setara dengan 315 kg/cm²)[1] .
Gigi-gigi buaya runcing dan tajam, amat berguna untuk memegangi mangsanya.
Buaya menyerang mangsanya dengan cara menerkam sekaligus menggigit mangsanya
itu, kemudian menariknya dengan kuat dan tiba-tiba ke air.Buaya memangsa ikan,
burung, mamalia, dan kadang-kadang juga buaya lain yang lebih kecil bahkan
bangkai buaya dewasa. Reptil ini merupakan pemangsa penyergap; ia menunggu
mangsanya hewan darat atau ikan mendekat, lalu menerkamnya dengan tiba-tiba.
Sebagai hewan yang berdarah dingin, predator ini dapat bertahan cukup lama
tanpa makanan, dan jarang benar-benar perlu bergerak untuk memburu mangsanya.
Meskipun nampaknya lamban, buaya merupakan pemangsa puncak di lingkungannya.
Pada musim kawin dan bertelur buaya dapat
menjadi sangat agresif dan mudah menyerang manusia atau hewan lain yang
mendekat.Di musim bertelur buaya amat buas menjaga sarang dan telur-telurnya.
Induk buaya betina umumnya menyimpan telur-telurnya dengan dibenamkan di bawah
gundukan tanah atau pasir bercampur dengan serasah dedaunan. Induk tersebut
kemudian menungguinya dari jarak sekitar 2 meter.
Ukuran tubuh buaya sangat bervariasi dari
jenis ke jenis, mulai dari buaya kerdil hingga buaya muara raksasa. Spesies
bertubuh besar dapat tumbuh lebih panjang dari 5 m dan memiliki berat melebihi
1.200 kg. Walaupun demikian, bayi-bayi buaya hanya berukuran sekitar 20 cm
tatkala menetas dari telur. Spesies buaya terbesar adalah buaya muara, yang
hidup di wilayah Asia Tenggara hingga ke Australia utara.
Crocodiles are large reptiles that live in
water. Crocodiles generally inhabit freshwater habitats like rivers, lakes,
swamps and other wetlands, but there also live in brackish water such as
estuarine crocodiles. Crocodile is the main food animals such as the vertebrate
fish, reptiles and mammals, sometimes prey on mollusks and crustaceans depend
on the species.
Crocodiles are ancient animals, which is only slightly changed because of evolution since the time of dinosaurus.Buaya can move very quickly over short distances, even out of water.
This beast has a very strong jaws, which can bite with incredible power, making it an animal with the biggest bite force. Crocodile bite pressure is not less than 5,000 psi (pounds per square inch; equivalent to 315 kg / cm ²) [1]. Crocodile teeth pointed and sharp, very useful for holding prey. Crocodile attacks its prey by biting prey to pounce at the same time, then pull firmly and abruptly into air.Buaya prey on fish, birds, mammals, and sometimes also other, smaller crocodiles and even crocodile carcass of an adult. This reptile is an ambush predator, he waited for prey, land animals, or fish over and jump on him abruptly. As the cold-blooded animals, these predators can survive long enough without food, and seldom really need to move to hunt their prey. Although it seems slow, crocodiles are top predators in their environment.
In the breeding season and nesting crocodiles can be very aggressive and easily attack humans or other animals that mendekat.Di spawning season is very ferocious crocodiles guard their nests and eggs. Parent female alligator usually keep their eggs with buried under mounds of earth or sand mixed with the litter of leaves. Parent then stayed with him from a distance of about 2 meters.
Crocodile body size varies greatly from species to species, ranging from the dwarf crocodile to the giant estuarine crocodiles. Large-bodied species can grow longer than 5 m and has a weight exceeding 1,200 kg. However, babies only crocodile measuring about 20 cm when hatched from eggs. Largest crocodile species are estuarine crocodiles, which live in Southeast Asia to the northern Australia.
