Crocodile snouts more sensitive than human fingertips

    That is excellent stuff. Strange that alligators don't have the coverage that crocs do. Obviously they don't need it to be that way. But why? Could it just be alligators are more developed evolutionary wise? No I don't think so myself.

    I am more inclined to think that the head first approach is used by both but for an alligator it is the only approach. Crocodiles seem to be able to find food in any direction, and this could be a survival strategy. AND it could also be a defence strategy too. Crocs have often been depicted as attacking each other, it would be useful to know a bigger badder beastie is coming at you while you are not looking.

    Interesting thought, because crocodiles are known to be faster and more aggressive than gators... (not that gators can´t be nasty but gator keepers take liberties with their charges that they would never take with adult crocodiles- I know this for personal experience).

    Like I said, it would be interesting to know if caimans were included in the study, as they are more closely related to alligators but are usually faster and more aggressive if I'm not mistaken.
