Crocodile and Alligator are often assumed to be the same as both are semi-aquatic reptiles. There is a difference between them that is distinct.
Both the crocodile and alligator are reptiles living on both land and waters have sense and pressure receptors.
The integumentary sense organs or dermal pressure receptors help them to locate their prey. This receptor is present on the entire body of a crocodile and presents only on the jaws of the alligator. It’s quite easy to spot the difference between the crocodile and alligator.
