So why have crocs remained the same for so long?
The answer is evolution, they have evolved to a state where they are perfectly developed for their environment and therefore any genetic mutations are either a disadvantage and therefore selected out or neutral (what could you change in a croc that would not be a disadvantage?)
I'm surprised IDists and crerationists haven't used the obvious link to the design principle, "If it ain't broke, don't fix it." Doesn't it take an intelligent entity to determine that a creature is "just right"?
