There are a few speices that keep their body temps warmer than the water they live in.
Know the names?
I read that swordfish is warmer-blooded about twenty years ago.
I would assume that most large fast-swimming fish are a few degrees warmer than the water they are in. The temperature should depend on the species and on the environment.
It is just a thought. I have no idea how it related to the color of the muscle.
I wonder whether or not the internal organs are warm. I would assume that at least the heart is.
Yeah, I've got a list at home (I'm at the zoo right now). I'll dig it up when I get done this afternoon. Alot of them on my list are sharks and other marine fish. It's by no means a complete list in any way, but it should give you an idea.
Tuna and most all of the sharks in the Lamnid family (Mackeral sharks). Species that belong to the lamnid shark family are the salmon shark, white shark, porbeagle, shortfin mako and longfin mako.
most of the baddest sharks out there are this way. the great white and mako are my two favorites though
Tuna can literally "cook" themselves when you fish for them, during the fight.
That is why it is best to reel them in quickly or else they might not be able to live because of the dead muscle tissue. It is ok though if you are going to eat them. Its just because they move, at such high speeds and their muscles contract and release so quickly.
