The Bengals are better used to demonstrate the role of "mimicry" in Nature. Similiar to how the inoffensive scarlet king snake mimics the coloration and patterns of the far more deadly coral snake, the Bengals disguise themselves as a professional football team. They are very similiar in appearance to the more dangerous football team known as the "Cleveland Browns", but don't be fooled.
If confronted by a member of either team, look for the tell-tale marks on the player's helmet. The Cincinnati Bengal will have "tiger-like" stripes covering both sides, whereas the Cleveland Brown has a single white stripe, bordered on each side by black stripes that run from the forehead to the back of the helmet.
You are also more likely to encounter a Cleveland Brown in the "end zone" than you are to find a Cincinnati Bengal. Cincinnati Bengals are usually found deep in their own territory, and spend a greater than average amount of time "defending".
