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 ]
Exploding whale. Iconic 1970 whale explosion in Florence, Oregon, filmed by KATU news, one of the most widely reported cases of the exploding whale phenomenon. Note this explosion was intentionally caused using dynamite, but whale carcasses may also burst on their own. There have been several cases of exploding whale carcasses due to a buildup ...
The decline of global whale populations Blue whale populations have declined dramatically due to unregulated commercial whaling, putting them at risk of extinction.. Prior to the setting up of the IWC in 1946, unregulated whaling had depleted a number of whale populations to a significant extent, and several whales species were severely endangered.
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 ...
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.
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 ...
Cetacean surfacing behaviour is a grouping of movement types that cetaceans make at the water's surface in addition to breathing. Cetaceans have developed and use surface behaviours for many functions such as display, feeding and communication. All regularly observed members of the order Cetacea, including whales, dolphins and porpoises, show a ...
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 ...
