Fish and Temperature
I am doing a project on a sand tiger shark and i was wondering if
temperature variations (higher or lower) cause a difference in
respiration/breathing of the animal. Answer can be on shark or any fish.
Definitely-especially if your shark is ectothermic (ie. cold-blooded). Some
sharks are endothermic however. You need to know which yours is to actually
make a hypothesis.
Yes, but sharks normally stay in waters of approximately the same
temperatures. All heterothermic animals are dependent upon the
environmental temperatures in order to operate. The classic experiment
performed in many biology classes is to adjust the temperature of a
goldfish water and count its gill motions. A nice curve results.
