Answer:
- What is the function of a crocodile arm?
The limbs (both front and hind) are splayed out to each side, partially above the water meniscus. Like the fins of a fish, they prevent the animal from rolling uncontrollably in the water, and also help to stop it from sinking - although the air in the crocodile's lungs is primarily responsible for that.
Crocodiles and humans have very similar hearts, each with four chambers. The acid activates a enzyme known as pepsin which is secreted from the walls, which allows protein to be broken down. ... Crocodiles swallow their food whole if possible, other wise they tear their food into smaller chunks.
