no, iguana's are reptiles, meaning a mammal, you don't find them under water! The only mammals under water are dolphins, turtles, sea cows and whales. Hope this helps!
fish are fish. if they could breathe above water they would be a mammal. no fish have lungs only.
No not really and they could only if they catch a little drop of blood in nearby water of the mammal it will attract many sharks.
No one can yet live on mars. The only thing that isn't a mammal or cannot fly that can survive on mars, is the water bear. It can be seen under a microscope.
No. There are dolphins, porpoises and manatees as well.
A bat is the only flying mammal.

No, a fish is not a mammal. Only a mammal has a backbone.
Because there mammal's and therefor can only breathe above water
Bat is the mammal that can only fly.
Funny. Only three mammals are in the sea. (Whale,Dolphin,Seal)
A dolphin is a (marine) mammal. I could see why you may have thought amphibian, however an amphibian is more of a frog/lizard species.
