Where do whales get their food?
It depends on which whales you are talking about. Different whales eat different things.
Is blue whale a type of dolphin?
No dolphins had a different evolution from whales. Whales evolved from a footed creature similar to a hippo (no, seriously) and dolphins evolved from a footed creature a lot smaller.
What could explain the external form of whales and fish being similar but the whales skeleton being similar to that of a mammal?
convergent evolution
Did cows evolve from whales?
No, though cows and whales come from a common ancestor being the Pakicetus. Cows are "sisters" to hippos, and both of these species are "cousins" to whales. Cows, like all other ungulates, have their evolution much farther back on the evolutionary tree than whales do. Whales came from mammals that went from being terrestrial to oceanic in a matter of 8 million years. See the related link below for more info.
Why has evolution made whales look similar to fish?
It is called convergent evolution. When two different animals have to adapt to the same environment (both whales and fish have to adapt to marine environments) evolution will make them start to look similar, even though they will still retain fundamental differences. For example, whales are mammals, and fish are... fish
What is ambulocetus an ancestor to?
Animals of the genus Ambulocetus are intermediaries between basal mammals and modern whales, and possibly ancestral to modern whales.
Are dolphin and whales the same?
No, whales are big and dolphins are small... If that's not enough of an answer I can ramble for you... is that what you want? Ok then, they are very similar in the fact that they treat their young the same, have the same basic biological makeup and are both mammals but it is relatively easy to see that they are different animals because they are not only in different species but, in different genuses' so in scientific lingo, they are about as similar as your friends housecat and a tiger.
How does whaling industry work?
The whaling industry was very similar to modern fishing industries. The whalers would go out on boats and hunt whales. They would catch the whales, process the meat and also the oil from the whales which was used as a heating oil and such. They would then return to port and sell the meat and oil the markets and such.
Are right whales ballean whales?
No. Baleen whales and Right whales are both different types.
Who roamed the land a long time ago?
When whales walked on all fours The ocean's largest animals' forebears previously walked on land. Follow them on their incredible adventure from coast to sea. Whales, although being great swimmers and completely adapted to life underwater, used to walk on four legs. Their land-dwelling forefathers lived approximately 50 million years ago. Meet Pakicetus, a goat-sized, four-legged creature recognized by scientists as one of the first cetaceans (the group of marine animals that includes dolphins and whales). One of the most fascinating evolutionary journeys known to science is that of Pakicetus' ancestors evolving into whales. What were the first whales like? Pakicetus (seen above) had no resemblance to a whale, but it would have felt at home in the water. It existed on land, among lakes and riverbanks in what is now Pakistan and India. It hunted small terrestrial creatures as well as Freshwater Fish, and it could even hear underwater. This animal's relatives eventually travelled further into the ocean and adapted to cope with their new habitat. Into the sea Ambulocetus was the name given to one of these relatives. Around 50 to 48 million years ago, it resided in or near estuaries. It spent time in and out of the water like Pakicetus, but its huge feet resembled flippers rather than its ancestor's larger legs. It also swam by using its tail. Dorudon, which lived 40 to 33 million years ago, is found further down this evolutionary path. This five-metre-long creature has functional flippers and tiny hind legs. It spent its entire life in the sea and was an excellent swimmer. It also gave birth to its offspring while submerged. Cetaceans had totally adapted to living in the sea within 10 million years, from the time of Pakicetus to the time of Dorudon. That may seem like a long period, but in evolutionary standards, it is quite quick. Whales that lack teeth Dorudon's descendants went on to evolve into contemporary whales. A group of whales began to evolve a new style of eating some 34 million years ago. Their heads were flatter, and they had feeding filters in their mouths. These are known as baleen whales, and they include blue and humpback whales. Other whales, such as dolphins, porpoises, orcas, and sperm whales, preserve their teeth.
