Fish are not able to regulate their body temperature by producing heat. How could a fish adjust its body temperature if it were too warm?a. swimming into cooler water
b. evaporating water from its skin
c. expelling water from its body
d. speeding up its level of activity

Answers

The answer is A: Swimming into colder water. When fish are hot, they swim deeper; which is the same thing as swimming into cold water. B is incorrect, because if the fish is hot, there's no use going to the surface-which is hotter- to evaporate water from it's skin. By the way, what's the use of evaporating water again? The fish is still hot! C is wrong, because the only fish known to man that expels water, is the puffer-fish. Since the answer talks about fish in general, C is eliminated too. Finally, D is wrong because... um... someone please explain to me why a fish will speed up when the fishes temperature is getting hotter then supposed to!
