New Discover: Crocodiles Can Sleep With An Open Eye

 

If a crocodile feels in danger, it is capable of sleeping with an open eye to be alert of the things that happen around. This is the conclusion of a scientific study made in Australia and that was recently published in magazine Journal of Experimental Biology.

The study observed the behavior that they seem to be totally asleep but they are really watching with one eye and when the person or another animal goes away, they still keep looking to the direction where they noticed their presence.

This behavior suggests that, although they seem asleep, one part of their brains keeps active. But investigators need more evidence to determinate which part of the brain keeps alert and verify if the rest of the brain is really fallen asleep.

This monitoring capacity in the studied crocodiles is present in other reptiles, some birds and aquatic mammals like the dolphins.
