A pretty simple question, right? But the answer may be a bit more complicated than you think. First, we have to specify what exactly it means to be “cold blooded” with a few definitions.
We’ll start with the terms, endothermic and ectothermic. I’m sure you’ve got these down pat, as they probably were drilled into your head since the fourth grade. But if not, endotherms maintain optimal body temperature via internal processes (e.g. metabolism). On the other hand, ectotherms can’t use internal processes to regulate temperature, and must rely on outside sources.
The answer is Yes, Fishes are Cold-blooded. Meaning they get their body temperature from the surrounding water. … Temperature also affects metabolism and metabolic processes occur quicker in warmer water.
Fish, mammals, amphibians, reptiles, and birds are separate categories of vertebrate animals (animals that possess a spine). … Thus fish are neither mammals or amphibians.
Yes Salmons are cold-blooded
