Question

Is Osteichthyes endothermic or ectothermic?

Answer 1

Endothermic:

1. Endothermic animals are animals that are able to maintain a constant body temperature regardless of their ambient temperature.
2. Endothermic animals include all birds and mammals of the animal kingdom.
3. Some fish are considered to be endothermic.

Ectothermic:

1. An ectotherm is an organism in which internal physiological sources of heat play a minimal or insignificant role in regulating body temperature.
2. Such species (for example, frogs) rely on external heat sources, allowing them to function at very low metabolic rates.

Osteichthyes:

1. All bony fishes come under the class Osteichthyes.
2. These fishes are found in wide habitats such as oceans, rivers, and lakes.
3. Fishes included in this class are trout, salmon, halibut, and bass.
4. They also have a swim bladder and moveable fins.
5. They are ectothermic or cold-blooded animals, with 2-chambered hearts means their body temperature regulation depends on the external environment.
