I've fished for a long time and never have I ever seen something like this. If anyone has any knowledge about this creature I caught please let me know, it was caught off of Port Canaveral, FL, again any help would be great!!! By the way the tail is a bit cut off it has two dorsal fins and no barbs.

It sort of looks like a guitar fish. Related to sharks and rays.

It is an Atlantic guitarfish, Rhinobatos lentiginosus, a ray (Rajiformes) that looks like a shark. An angel shark, Squatina, is a shark that looks like a ray.

According to commonly cited info a shark has gills on the sides, a ray has gills underneath.

According to my college vertebrate zoology class their are two groups of sharks. One group mostly traditional sharks. The other a mix of traditional sharks, odd sharks, and tays which has everything from whale sharks and dogfish to angel sharks and rays,

to confuse things more between 1 (sharks and rays are different0 and 2 (rays are modified sharks) is wikipedia refuting 2 and supporting 1. So I have no idea where the issue stands now.

When in doubt, ignore wikipedia and go with a peer reviewed source.

FirstChAos,
I'm not sure what your point is, but a guitarfish is a ray, Elasmobranchii - Rajiformes - Rhinobatidae - Rhinobatinae, and yes their gill openings are on the bottom and they have spiracles just behind their eyes like any other ray/skate. A whale shark, Rhincodon typus, Elasmobranchii - Orectoloboformes - Rhincodontidae, is only related to Rajiformes on the class and order levels.

What is a "traditional shark"? By the way, Wikipedia is editable.

Wikipedia is peer reviewed. Irate mormon edits stuff, there, as do lots of other clever folks with very specific knowledge. Here's some of their own stuff...

Individual entries in Wikipedia may be peer reviewed, but they don't have to be. I use Wikipedia too but do not rely on it for specific scientific information. I like Michael's response - when in doubt, use a source that requires peer review prior to publication.
