There is no good data available on the total number of sperm whales in the wild (and they are not kept in captivity for the same reasons--deep divers and they remain submerged most of their life). They are just too difficult to count. While on the endangered species list, sperm whales are the most prolific of all whale species, and estimates put their total between 200,000 and 1,500,000.

There are not many killer whales left there are in danger so there are not that many left
Sperm whales have 42 chromosomes in total. This includes 21 pairs of chromosomes.
Sperm whales have 42 (2n) chromosomes.
How many killer whales were alive ten years ago?
Baleen whales are technically larger than tooth whales because the blue whale is the largest animal on the planet, but the sperm whale, which is a tooth whale, is pretty large.The baleen whales are normally larger, except for the sperm whale, which can be as long as many baleen whales.
An Sperm Whales can dive for about 5 mintures

The sperm whale is a toothed whale. The sperm whale could be the biggest animal in in existence that has teeth. It has big teeth (in it's lower jaw) to catch and eat large prey, such as the giant squid. Baleen is not a tooth, but, is a flexible plate, and baleen whales have many of them in the front of the mouths. Baleen whales, such as the blue whale, eat very small animals such as plankton by taking large amounts of water into their mouths. The whales then strain the water through their baleen, which traps the plankton inside, which are then swallowed. Whalers who caught sperm whales in the past, would sometimes take the large teeth and make drawings on them.
I don't believe there are hump back whales in captivity. There are many killer whales, but i don't think the aquarium owners could keep a whale that large.None.
its hard to tell but proabably 10
Extinct means all gone, no one left alive. And xince we still have whales, thay aren't extinct. But they are threatened, not many left. A bit more hunting, maybe some disease, could easily kill off all that are left.
No. First of all, despite the common name of "killer whale" orcas are in fact dolphins. But also, many whales (including humpbacks, sperm whales, and blue whales) are the prey of the orca.
