The head of a juvenile alligator. The relative proportions of different parts of the body grow at different rates in alligators as in other animals, so that adults can have quite different shaped heads (for example) compared with juveniles. In alligators, the snout grows relatively much more rapidly than the brain-case, and this is most notably seen in a change in the relative size of the eyes compared with the rest of the head. Juveniles have large eyes for their head size, adding to their appealing nature (behaviourally relevant in those animals in which maternal care of offspring is important) - this may not enhance the survivability of juvenile crocodilians in crocodilian circles, but it can be used to promote their cause to humans.
