Vestigial structure is used in application to structures that are determined genetically but do not have the ancestral function.
The term is "vestigial structure." These structures are remnants from an organism's evolutionary history and no longer serve a function in the current organism. Examples include the human appendix or tailbone.
On a dolphin and most fish the fin behind the dorsal fin is the tail fin. Some fish, such as knife fish, have no dorsal fin or tail fin. Dolphins of course are mammals, not fish.
A vestigial structure is a structure that an organism still has but no longer serves any real definite purpose. In this case, the whiskers on a cat serve a vital purpose, so they are not vestigial structures.
