Most sharks are cold-blooded. Some, like the Mako and the Great white shark, are partially warm-blooded (they are endotherms). These sharks can raise their temperature about the temperature of the water; they need to have occasional short bursts of speed in hunting.

Mammals all are warm-blooded animals, they breathe air, have hair, and moms feed their babies milk from mammary glands. Whales actually do all of these things! Whales are warm blooded, which means they keep a high body temperature that does not change in the cold water. ... So whales are indeed mammals and not fish!

No, there are no cichlids who are able to live in cold water. Cichlids come from tropical regions and therefore need tropical temperatures. Keeping them in cold water will cause stress and lower their immune system making them prone to disease. It is important to know the minimal temperature for your cichlids.

Q: Is an octopus a mammal? ... And no, the octopus isn't a fish, either. All fishes have backbones and gills and most of them have scales and are cold-blooded (they take on the temperature of their environment). While octopuses have gills and are cold-blooded, they do not have backbones or scales.

Though almost all fishes are cold blooded, yellowfin tunas have a specialized blood vessel structure – called a countercurrent exchanger – that allows them to maintain a body temperature that is higher than the surrounding water.
