Crocoduck

A crocoduck is a hypothetical creature with the head of a crocodile and the body of a duck.

The chimera is based on a fundamental misunderstanding of the concept of biological evolution, and yet has been used by advocates of creationism (such as Kirk Cameron and Ray Comfort) to argue against the evolutionary model.

The crocoduck does nothing to undermine the theory of evolution, however, because the evolutionary model does not describe the hybridization of contemporaneous species (those co-existing with each other in time), nor does it describe the formation of a new species from two co-existing species.
