The most expensive crocodile in the world

The most expensive crocodile in the world is the albino crocodile.

From the appearance alone, crocodile's eyes are like a ruby embedded in a piece of white jade, because all albino crocodiles are white except red eyes, and the probability of their appearance is slightly higher than that of white lobsters, but the probability is also very low. There is only one crocodile in every 6,543.8+100,000 crocodiles, and there are only 20 albino crocodiles in the world at present.

Because white crocodiles have no protective color, it is difficult to survive in the wild, so no one has ever found white crocodiles in the wild, even though they may have been killed by predators.

Brief introduction of crocodile

Crocodiles are one of the earliest and most primitive animals discovered so far. A fierce vertebrate reptile, which appeared in Mesozoic from Triassic to Cretaceous (about 200 million years ago), was a carnivore at the same time as dinosaurs.

Crocodile is a cold-blooded egg-laying animal, not a fish, but a reptile, the name of crocodile, or because it plays in the water like a fish, it is named "crocodile".

The adaptability of crocodiles to the environment is shown in the following aspects.

1, the evolution of the head is exquisite, which can ensure that only the ears and nose are exposed to the water during hunting, which greatly maintains the concealment.

2. Reptiles have an unusually developed heart with four atria, while normal reptiles have only three atria, which is close to the level of mammals.

3. When hunting, the heart can transport most oxygen-enriched blood to the tail and head, which greatly enhances the explosive force.

4. The brain has evolved the cerebral cortex, so its IQ may be far beyond our imagination, even beyond the tiger.
