blue whale circulatory system

Blue whales are typically a blue-grey in colour.

The blue whale, which can reach up to 100 feet (30 meters) long and weigh 200 tons, lowers its heart rate to as little as two beats per minute as it lunges under the ocean surface for food, researchers said on Monday.. The tail flukes are triangular and are 25 ft (7.6 m) wide. Family: Balaenopteridae A study finds extreme ranges of heart rates in blue whales during diving, feeding, and surfacing. 4. www.seaworld.org/animal_bytes/bluewhaleab.html "Blue Whale" Wildlife Fact File, IM Pub Inc, USA Indeed, it is even the largest of all the mammals — it is the largest known animal (although not the longest - giant squid have been found over 200 ft long including tentacles.)!

The mating season occurs in the early spring when they reach the warmer waters.

The head is large, wide and flat. It can dive to depths of 1650 ft (495 m). The flippers are tapered. The flippers are lighter than the body, and the underside of the are flukes darker. Any krill in that water are trapped by the bristles and are scooped up by the tongue and swallowed. Their calls can reach 188 decibels and travel hundreds of kilometers underwater. It can dive to depths of 1650 ft (495 m). Due to overhunting by whalers for their oil and blubber, the entire species was almost exterminated. 6. mbgnet.mobot.org/salt/whale/blue.htm are not responsible for the accuracy of news releases posted to EurekAlert! The blue whale has a long, streamlined body that tapers off to form a tail, which ends with the tail flukes. Along with their mental capabilities, adaptation to bipedal, locomotion (which frees the hands for manipulating objects) has allowed humans to make far greater use of.
