why whales are not grouped in the fishes?
Answers
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!
Whales are warm blooded, which means they keep a high body temperature that does not change in the cold water. Fish are cold-blooded, so their body temperature changes depending on the temperature of their environment. Whales actually breathe air with lungs using their blowholes to breath out!
Even though they live in the ocean all of the time, dolphins are mammals, not fish. Also, dolphins are different than "dolphinfish," which are also known as mahi-mahi. Like every mammal, dolphins are warm blooded. Unlike fish, who breathe through gills, dolphins breathe air using lungs.
