They're both aquatic mammals
I would say that the blue whale, and the sperm whale were least common.
no they are not
Blue whales can produce over 40 gallons of sperm .
they are whales trust me
Blue Whales, Beluga Whales, Killer Whales, Sperm Whales, and Narwhals.
Blue whales are usually about 30m long and Sperm whales are usually between 13 and 20m long. So Blue whales are usually 10-17m longer than sperm whales. (This is just the average length of these whales, bigger and smaller specimens do exist)
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.
The product from whales that was used in cosmetics--it's not anymore--is spermaceti, which comes from sperm whales rather than blue whales.
Killer Whales,humpback whales,sperm Whales And I Think Blue Whales Too.
North Pacific Right Whale, North Atlantic Right Whale, Blue Whale What he/she means is that the whales in the North Pacific and North Atlantic and the blue whales are endangered because either they can't find enough food, or they are being illegally hunted.
well kinda yes since there are like blue whales, sperm whales, killer whales, and etc.
The blue whale is the fastest, the sperm whale is not far behind and the right whale is the slowest. The blue whale would be the only one with a well defined fin (a dorsal fin) on it's back. A sperm whale (like all toothed whales and dolphins) has a single blowhole at an angle on the top/front part of its head, so it has a single blow that comes up at an angle. A right whale (like all baleen whales) has a double blowhole on the top of its head. It has a double blow. A blue whale, even though it also has a double blowhole has a high and straight blow. There are several good field guide books that show the difference between the blows of different types of whales.
