I think all it is, is either a small hawk or seagul that fell into the sea from a fight with another bird or animal. and it just lost all it's feathers.
But probably not idk. 
But it has teeth...
Also, the arms/wings are too short for a bird. Legs are obviously not bird, and the tail isn't right, either.
Ya know, come to think of it....
I remember reading something about a similar creature recorded I think sometime in the early 1800s somewhere in the NE US, or SE Canada. IIRC, there was some sorta creature which was sighted by a sea captain, and mentioned in the ship's log. It wasn't ever really considered noteable, other than that the critter was following them, and seemed to enjoy playing near the boat. Anyway, whatever it was hasn't been seen since, and hadn't been identified up to that point. Generally dismissed as some sorta normal animal that was poorly described, or else a generic "sailor story." Noteably, it was missing the common tone of a sailor story-- that is, it just treated the sighting like a perfectly normal event; nothign to write home about, whereas most stories would be some sorta tall tale of gerandiose proportions. This was just some random little incident recorded.
Anyway, point being that... um...
...I forgot the point. Yeah. There could be some sorta rare species that has been sighted before. Rarely, granted.
Now, when Champ washes up, THEN we'll have something to post about!
