I think they use some kind of net or something. Sorry if it doesn't help.
This depends on age and even gender. Blue whales weigh around 100-150 tons. So 2 blue whales at adulthood can weight around 250-300 tons.
About half a ton.
Blue whales are ocean dwelling mammals, they need the water to support their body weight, and for their food. The possibility of blue whales going into Mt Everest is 0.
Blue whales don't have a specific average weight. They do have a range which is round 100-120 tons. However, Blue whales can weigh as much as just over 200 tons.
Yes they are animals, because whales are animals.
This isn't always the same. Some say that it is because they are adapted to be able to carry more weight during pregnancy. For example with blue whales females measure at 3 feet longer and the biggest whale was a female.
because there is so much open space for them to live in. And also with there size and weight, they have no natural ememies.
In 1930-31, over 29,600 were caught.
Roughly 250, 000 kittens to 4 blue whales. Taking the average weight of a blue whale as 250, 000 lbs and the average weight of a kitten as 4 lbs.
Blue whales are carnivores, feeding on small crustacean's, plankton, and any small fish that get caught up when feeding.
Because we live in a messed up world...
Blue whales are endangered because of over one hundred years of over hunting by whalers.
