Detailed explanation-1: -Fishes are aquatic organisms that belong to the kingdom Animalia. Warm-blooded animals can maintain constant internal body temperature. This is in contrast with cold-blooded animals that cannot regulate their internal body temperature. Fishes are cold-blooded.
Detailed explanation-2: -Not all fish are cold-blooded. In 2015, researchers with the NOAA Southwest Fisheries Science Center revealed the opah, or moonfish, as the first fully warm-blooded fish.
Detailed explanation-3: -For over 50 years now, scientists have known that, despite their reputation, not all fish are cold-blooded. Some shark and tuna species, the white shark and the Atlantic bluefin tuna, have evolved the ability to warm parts of their bodies, such as their muscle, eyes and brain.
Detailed explanation-4: -Animals that cannot generate internal heat are known as poikilotherms (poy-KIL-ah-therms), or cold-blooded animals. Insects, worms, fish, amphibians, and reptiles fall into this category-all creatures except mammals and birds.
