What is the difference between a whale and a fish?
The most basic difference between the two is that whales are warm blooded mammals, whereas fishes are marine animals. Fishes and whales are both vertebrates, and live in similar aquatic environments. Except for a few species, whales only live in the ocean water, whereas fishes inhabit in both fresh and salt water.
Is whale is a fish?
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!
Are whales and fish similar?
Though whales are mammals and fish are not, they are similar in some ways. Both have fins and a tail, which helps them swim and stay upright in the water. But these similarities are in appearance only. Fish, on the other hand, have vertical tails, which move from side to side.
Do whales lay eggs?
Do whales lay eggs? The answer is no. Because whales are marine mammals, the females carry the offspring in their wombs and have live births! However, since whales are fully aquatic mammals, how whales give births is much different than the births of terrestrial and semi-aquatic animals.
Do whales hair?
Believe it or not, whales do have hair, although it’s only visible in some species. One of those is the humpback whale. The golfball-sized lumps you see on a humpback’s head each house a hair follicle. Fin, sei, right and bowhead whales also have hair follicles.
Do whales eat fish?
They are carnivores that love to eat fish. Their teeth are not used for chewing, only for capturing and holding on to the food. Baleen whales feed by filtering or straining food from the water.
Do whales have nipples?
Do whales have nipples? Seals and sea lions have retractable nipples that tuck inside the body when the baby is not feeding, but animals that are fully restricted to the sea, such as whales and dolphins, have evolved ‘mammary slits’ – special folds of skin that enclose the feeding glands.
Can whales breathe water?
Whales and dolphins are mammals and breathe air into their lungs, just like we do. They cannot breathe underwater like fish can as they do not have gills. After each breath, the blowhole is sealed tightly by strong muscles that surround it, so that water cannot get into the whale or dolphin’s lungs.
What are baby whales called?
Baby whales are often referred to as “calves”, whereas mothers are referred to as “cows”. Males are sometimes referred to as “bulls”.
Can whales eat humans?
No, whales do not eat people; they primarily eat small aquatic lifeforms such as fish, squid, and krill, and a few dolphin species are even known to eat marine mammals such as seals, sea lions, walruses, and whales. Still, they are not known for consuming or eating people.
What do whales drink?
Even though they can drink salt water, whales are thought to get the bulk of the water they need from their prey – which includes, fish, krill, and copepods. As the whale processes the prey, it extracts water. In addition, whales need less water than we do.
Can humans drink whale milk?
Whale’s milk, not used for human consumption, is one of the highest-fat milks. It contains, on average, 10.9% protein, 42.3% fat, and 2.0% lactose, and supplies 443 kcal of energy per 100 grams.
Why are whales classified as mammals and not fish?
Whales even give birth to live baby whales that will get milk from their mom for food. Fish lay eggs, which must still grow into a baby fish. So whales are indeed mammals and not fish! Whales are mammals because they share the characteristics of other mammals (like us!).
Is a whale shark a mammal?
Whale sharks don’t produce milk
How are fish and mammals different?
– Fish are cold-blooded, scaly bodied, laterally flattened bodied, and finned whereas the mammals are warm-blooded, hairy bodied, not flattened, and mostly four-legged in the body forms. Both fish and mammals are equally important for the humans in umpteen ways.
Is a whale a fish?
Whales are not fish. They are marine mammals, as are dolphins and porpoises. They are warm-blooded and breathe air like humans.
