Want this question answered?
no the blue whale is not the only endangered species of whales there are others like the humpback ,southern right whale,sperm whale and the killer whale the orca
It is estimated that the lifespan of the Southern right whale is 50 to 70 years. It used to be endangered and people are working very hard to keep it unendangered.
Many whales are endangered, so there is no actual answer for this question. Most whales have become endangered because of whaling, or whale hunting. Here are a few endangered whales: -Humpback (not endangered), over 80,000 left -Blue Whale, between 10,000 and 25,000 left -Fin Whale, only 119,000 left -Sperm Whale, only 360,000 left -Right Whale, 450 North Atlantic Right Whale left, due to harsh whaling (it is named after whalers who called it the "right" whale to catch)
Because whalers favored the whale so much that they called it the "Right" whale to kill, hence its name. They have never fully recovered despite bans on hunting them.The right whale is endangered because it was the most hunted. It was called the right whale by whalers because it floats when dead, is slow-moving, and has good oil and blubber.
PEOPLE KILLED THEM.='.'=
they got threatenened
They are endangered , but studies are underway, monitoring the population and the hunting of them.
it has just become endangered http://www.environment.nsw.gov.au/determinations/BlueWhaleEndSpListing.htm
Full grown Southern Right Whale's only known predators are humans. Southern Right Whale calves are occasionally hunted by Orca Wales and large sharks.
the minke whale or the southern right but that's a right whale
This depends on the subspecies of right whale. Southern right whale can measure to 59 feet. Northern right whale can measure to 60 feet.
