Question

Are fish warm or cold-blooded?

Answer 1

Fishes:

1. Fishes are aquatic organisms that belong to the kingdom Animalia.
2. Warm-blooded animals can maintain constant internal body temperature. This is in contrast with cold-blooded animals that cannot regulate their internal body temperature.
3. Fishes are cold-blooded. However, there are a few exceptions.
4. Some recent studies suggest that opah (moonfish) is a warm-blooded fish. Opah circulates warm blood throughout the body and survives in the cold ocean.
5. White sharks are partially warm-blooded. They can increase the temperature of certain body parts which in turn help them in swimming.
