A mass stranding of pilot whales on the shore of Cape Cod, 1902. Cetacean stranding, commonly known as beaching, is a phenomenon in which whales and dolphins strand themselves on land, usually on a beach. Beached whales often die due to dehydration, collapsing under their own weight, or drowning when high tide covers the blowhole. [ 1 ]
The interactions between marine mammals and sonar have been a subject of debate since the invention of the technology. Active sonar, the transmission equipment used on some ships to assist with submarine detection, is detrimental to the health and livelihood of some marine animals. [1] Research has recently shown that beaked and blue whales are ...
Whale barnacles are species of acorn barnacle that belong to the family Coronulidae. They typically attach to baleen whales, and sometimes settle on toothed whales. The whale barnacles diverged from the turtle barnacles about three million years ago. Whale barnacles passively filter food, using tentacle-like cirri, as the host swims through the ...
Dr Lillie said: “So if cetaceans (aquatic mammals that include whales, dolphins, and porpoises) can’t use their respiratory system to moderate pressure pulses, they must have found another way ...
According to federal data, more than 30 whales have been found washed up along the eastern shore since Dec. 1, with over a dozen of them off the coast of New York and New Jersey. To get a sense of ...
There is an argument that whales should not be killed because of their high intelligence. [29] Pro-whalers claim that pigs also possess high intelligence, and are routinely butchered and eaten, and that intelligence should not be the determining factor of whether an animal is acceptable to eat or not.
Here's why you should care about killer whales. Killer whales play an important role in our ocean's ecosystem. Female orcas can live up to 90 years, and male orcas live up to 60 years. Whales can ...
With so many vessels, the air quality around these whales deteriorates and impacts their health. Air pollutants that bind with exhaust fumes are responsible for the activation of the cytochrome P450 1A gene family. [219] Researchers have successfully identified this gene in skin biopsies of live whales and also the lungs of deceased whales.
