Blue Whale | Online Learning Center | Aquarium of the Pacific Sometimes theyll also slap their tails against the water. Whales have adapted special adaptations to help them thermoregulate. They cool off by sending warm blood to their external body parts (dorsal fins, flippers, and flukes). These extremities have thinner layers of blubber, or none at all, so the heat in the body can be lost to the cooler water washing over the extremity. Whales typically mate during the winter months, and the process can be quite complicated. Blue Whales are known for their powerful hunting skills, which enable them to kill giant marine mammals such as seals and Sea Lions. Solitary whales are usually less sociable than social whales and might spend more time alone. Estimated blue whale populations today are 400-1400 in the Southern Hemisphere, 5,000 in the North Pacific with about 2-3,000 of those in the California population, and possibly 1,000 in the North Atlantic.

From the 1900s through the 1960s, whale hunting accounted for the deaths of an estimated 360,000 blue whales, which caused them to become endangered. For North Atlantic right whales, acoustic crypsis can come in two forms: reducing the amount of calls they produce and reducing the amplitude/loudness with which they propagate those calls. Details, Women's level of Myoglobin. Surely, they must have some opinions, given that they live in our homes, work with us, and even become our friends.

Inside of their mouths are plates of baleen, sheets of keratin that allow them to filter food out of sea water, and atop their heads are two blowholes used for breathing. Whales have a large brain size compared to other mammals, which allows them to process complex information quickly. The reason for this is that Echolocation is extremely useful in areas where visibility is low and helps whales avoid colliding with other objects when they cannot see what is around them. Blue whales swim usually individually or in small groups, with pairs commonly spotted as well. Blue whales now became the most targeted whale because of their profitability.

There are three extant families of seals which are subdivided into 14 genera and 18 species. Since acoustic signals can rely messages over long ranges with relative accuracy underwater, theres an inherent increase in their risk of eavesdropping/interception by predators such as sharks and orcas.
