How Often Does a Blue Whale's Heart Beat?Įven if a blue whale is getting nervous or physically exhausted, his heart only beats about 18-20 times per minute. Normally, they can hold their breath for 3-10 minutes, in extreme cases even up to 20 minutes. How Long Do Blue Whales Dive?īlue whales come up for air at least every two minutes. Behavior What Do Blue Whales Eat?īlue whales munch 4-8 tons of plankton, krill and small fish every day. The heart of an adult blue whale is as big as a golf cart. At its birth, a blue whale baby weighs about two tons, just like two small cars. Its tongue alone weighs as much as a young elephant (think of this when you visit the elephants in the zoo next time!). Therefore we offer you a few comparisons: The weight of one blue whale equals that of four large brontosauruses, 23 elephants, 230 cows or 1,800 humans. ![]() It is always difficult to get an idea of big dimensions. Size and Weight Size and Weight Comparison Yet, the longest animal is the slim giant ribbon worm. The blue whale is the largest and heaviest of all animals living on shore, in the air and in the water. Like all whales, hunting of the blue whale is prohibited by US law and they are protected in US territorial waters.Main Characteristics The Blue Whale is The Largest and Heaviest Animal Today, the whale is listed as endangered by the International Union for the Conservation of Nature ( IUCN). Prior to their population being decimated in the 1900s, Blue whales existed across the globe in large pods, which could number 230,000 or more individuals. They stay close to the surface of the water where krill is plentiful and generally live in extended family groups called pods. They are pelagic animals, meaning they live almost exclusively in the open ocean, rarely straying into coastal areas near land. īlue whales are found in every ocean on Earth but do not roam to the polar regions. The body color is gray in most individuals, although it can sometimes be mottled with patches of darker gray, black or blue. Compared to its size, it has an extremely small dorsal fin. The head is flat and has a distinctive U-shaped crest which reaches from the blowhole around the perimeter of the upper jaw. Still, blue whales can be identified by a long, tapering body which is more slender than most other whale species. That’s comparable to a human being eaten 32,000 quarter-pound hamburgers each day!īecause the whales are so large, they are difficult to photograph or even observe in the natural environment unless done from the air. A typical adult whale may consume up to 4 tons (3.6 metric tons) of krill every day. The baleen acts like a net which catches the krill but allows water to pass through. They use fringed plates of baleen attached to the upper jaw to filter their food out of the water. They are also the largest carnivore, although they prey almost exclusively on tiny shrimp like animals called krill. Their newborns measure over 25 feet (8 meters) in length and weigh as much as 3 tons (2.7 metric tons). The whales are so big that when they spout their spray has been recorded as reaching 30 feet (9.1 m) into the air. This gentle and reclusive cetacean is the largest animal to ever live on Earth. With adult specimens measuring up to 98 feet (30 m) in length, no animal, either terrestrial or marine, modern or prehistoric, has come close to the sheer size of the blue whale. ![]()
