Haha, lol. Here is a resource that talks about a lot of stuff but goes over how fish can deal with changes in temperature. still looking for something more direct http://coolcosmos.ipac.caltech.edu/image_galleries/ir_zoo/coldwarm.html Tthis one is a good one- it talks about different types of thermoregulation. both physiological and physiological thermoregulation... http://www.earthlife.net/fish/tregulate.html

Most fish are cold-blooded as this resource says... and it talks about how they regulate their temperature. So you can see that really they don't have GREAT means of changing their body temp!
