Southern blue whales are about 3.5 m (11 ft) larger than northern, a difference believed to be the result of the more abundant supply of krill in the Antarctic Ocean. 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. This behavior is considered part of whale communication and can help establish relationships between individuals. 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.

Researchers have determined the diet preferences of Californias blue whales by analyzing fecal specimens. While its large size might suggest a dangerous animal, the whale shark is actually a gentle giant and will permit divers to approach it closely without exhibiting aggressive behavior. copyright issues | During periods of rest, whales can often be found logging around (resting motionless) at or near the surface of the water so that they can easily obtain oxygen whenever necessary. Adaptations are the result of evolution. In addition to having ears toothed whales also use a method known as echolocation to help them navigate the ocean, find food and avoid potential threats. In late December 2012, NOAA announced that beginning in 2013, shipping lanes along the California coast would be adjusted to protect feeding and congregating blue, fin, and humpback whales from ship strikes.

Around 2,000 blue whales live off the California Coast and migrate south to Mexico and Costa Rica. Their results were consistent with their hypothesis, providing evidence that right whale mother-calf pairs exhibit acoustic crypsis by reducing the number of higher amplitude calls they produced compared to the juvenile and pregnant whales in the same habitat. Initially blue whales were not a target species of whalers because their size and speed made them difficult to catch, kill, and retain. These mammals are among the loudest species on the planet, releasing a series of pulses, groans, or moans to communicate with other whales who can hear them from up to 1,000 miles away in good conditions. Some of the more common behaviors observed in belugas include tail-slapping, breaching, spyhopping, and bubble blowing. cetacean, (order Cetacea), any member of an entirely aquatic group of mammals commonly known as whales, dolphins, and porpoises.

A recent study by Parks, Van Parijs, and Nowacek hypothesized that if the calves of North Atlantic right whale mother-calf pairs are in their first three months after birth (when theyre most vulnerable to predation), then the mother-calf pair will exhibit acoustic crypsis.
