As whales reach the water surface to breathe, they forcefully expel air through the blowhole. The exhalation is released into the comparably lower-pressure, colder atmosphere, and any water vapor condenses. This spout, known as the blow, is often visible from far away as a white splash, which can also be caused by water resting on top of the ...
Unlike other cetaceans, the belugas seasonally shed their skin. [44] During the winter, the epidermis thickens and the skin can become yellowish, mainly on the back and fins. When they migrate to the estuaries during the summer, they rub themselves on the gravel of the riverbeds to remove the cutaneous covering.
Some species are well adapted for diving to great depths. Almost all have a layer of fat, or blubber, under the skin to keep warm in the cold water, with the exception of river dolphins. Toothed whales consist of some of the most widespread mammals, but some, as with the vaquita, are restricted to certain areas.
Breathing involves expelling stale air from the blowhole, forming an upward, steamy spout, followed by inhaling fresh air into the lungs; a humpback whale's lungs can hold about 5,000 litres (1,300 US gal) of air. Spout shapes differ among species, which facilitates identification. [38] [39] All whales have a thick layer of blubber. In species ...
Researchers studying the majestic creatures have discovered the animals aren't just jumping for fun -- it's an important way to communicate.
The gray whale (Eschrichtius robustus), [1] also known as the grey whale, [5] is a baleen whale that migrates between feeding and breeding grounds yearly. It reaches a length of 14.9 meters (49 ft), a weight of up to 41 tonnes (90,000 lb) and lives between 55 and 70 years, although one female was estimated to be 75–80 years of age.
The tight spaces cause high levels of stress and anxiety which results in violence to other whales and even death of whale trainers. Wild orcas can travel up to 62 miles a day, but captive orcas ...
Three humpback whales jumped out of the water in unison in Cape Cod in front of stunned onlookers on Monday, 24 July. Extraordinary footage captured by Robert Addie shows the huge creatures ...
