Yes, whales have some hair(although very little).
Whales and dolphins!
Whales and seals are both mammals. They fit the criteria of being warm blooded vertebrates with hair (yes, even whales have a little hair) that produce milk for their young. However, penguins are not mammals. Instead, they are flightless, semi-aquatic birds.
Yes they do. Like all mammals, whales breathe air into lungs, are warm-blooded, feed their young milk from mammary glands, and have some (although very little) hair.
Whales have tiny hairs on their backs, and mammals have to have hair to be classified as mammals, and fish CAN NOT have hair.
From the Related Link below: "A whale's smooth skin is an adaptation for swimming, and whales lose their hair before they are born. A newborn calf sometimes has a few sparse hairs around the rostrum." So they do qualify as mammals, because they have SOME hair at SOME point in their lives. All whales have hair they are mammals. All mammals have hair
no.
Blue whales have a bit hair on their skin as they are mammals.
no becase they are mammls
dolphins....whales...
Right whales, gray whales, humpback whales, and blue whales are baleen whales, which means that they don't have teeth. They cannot eat large fishes, seals, and sea lions. They only eat plankton.
I think Killer whales are danger because of blond hair.
