No. They are just as important.
Porpoises and dolphins are actually both toothed whales.
They are actually more related to dolphins than whales.
whales and dolphins both have fins, but dolphins are much smaller than whales
They are actually more related to dolphins than whales.
killer whales are known to be dolphins only enemy
I think that dolphins are probably faster than blue whales because dolphins are smaller than whales. Blue whales are MASSIVE and HUGE and they take a really slow time to get from one place to another. Dolphins are much smaller than blue whales, therefore, they're probably faster.
Free Willy is an orca, which is more commonly known as a killer whale. Orcas are more closely related to dolphins than to whales.
They are called marine mammals, more specifically cetaceans (whales, dolphins) rather than manatees or dugongs, or semi-aquatic mammals such as seals, sea lions, and otters.
No, dolphins did not evolve from men, no other species evolved from men. Dolphins are small whales. The closest land animal to the whale is the hippo. Or at least that is the current theory. So dolphins are more closely related to horses, cows, sheep, and deer than they are to people.
Whales, dolphins, and maybe a platypus.
I group of whales is called a pod. Although they are not technically whales, cetaceans such as dolphins, orcas and porpoises also travel in pods.
No, a beluga whale is a Whale. Actually, belugas are somewhere in between. Bigger than most of the true dolphins (Delphinidae), they are smaller than most of the whales. Belugas are most closely related to narwhals (family Monodontidae)
