Right Whales

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.

Massachusetts was the epicenter of American whaling back in the 19th century. The right whale was a common species in the seas off the state, and got its name from the fact it was the "right" whale to hunt because of its blubber reserves.

Right whales play a crucial role in their ecosystem by helping to maintain the balance of marine life. As large filter feeders, they consume significant amounts of zooplankton, which helps regulate these populations and supports the overall health of the ocean. Additionally, their presence influences the behavior and distribution of other marine species, contributing to biodiversity. Moreover, their nutrient-rich feces promote phytoplankton growth, which is vital for carbon cycling and supports the entire marine food web.

All whales are mammals. As are dolphins as well.

Right whales primarily feed on tiny zooplankton, particularly copepods and other small crustaceans. They use a feeding technique called skimming, where they swim slowly with their mouths open, filtering food from the water through their baleen plates. This method allows them to efficiently consume large quantities of plankton in their nutrient-rich habitats. Their diet is crucial for their energy needs, especially during calving and migration periods.

Yes it is possible. They are found along the east of the US, Newfoundland in Canada, Iceland, North Spain, West France, Norway and right around Ireland, so it is very possible.

Right whales eat mostly small sea creatures such as small fish and krill, a small shrimplike creature.
