In addition, the agency recorded 14 whale entanglements with fishing gear from May 17 to Oct. 20 of this year, four of them from commercial crabbers, one more than would prompt the end of the rest ...
The Southern Ocean, rich in nutrients but iron-deficient, experiences increased phytoplankton blooms due to whale feces, acting as a significant carbon sink. The phenomenon of whales defecating near the water's surface reverses the typical flow of nutrients in the ocean's biological pump, contributing to the "whale pump." Whales feed at deeper ...
Other localities of similar age on the South African west coast have also yielded many additional species of balaenopterids and sperm whales as well as ten species of beaked whales. Large sperm whale teeth of up to around ~20 cm (8 in) in length are common in Hondeklip Bay, indicating a high presence of large sperm whales like Livyatan in the ...
But there was a problem; as the boat gained on the whale, the whale started exhaling while still submerged. This produced a cloud of bubbles in the water that reflected sound better than the whale did and made a false target (akin to what a pilot does when releasing metal chaff to create a false radar echo).
Video shows the whale breaching the water and striking the rear of the boat. At least one of the boaters is seen plunging into the water. ocean whale breach animal wild (Courtesy Colin Yager)
The whale died in the shallow water off the public beach near the Palm Beach Pier, the article said. The Palm Beach Pier no longer exists, but at the time it extended out more than 900 feet from ...
A researcher fires a biopsy dart at an orca.The dart will remove a small piece of the whale's skin and bounce harmlessly off the animal. Cetology (from Greek κῆτος, kētos, "whale"; and -λογία, -logia) or whalelore (also known as whaleology) is the branch of marine mammal science that studies the approximately eighty species of whales, dolphins, and porpoises in the scientific ...
Unlike the other large filter feeders, it relies only on the water that is pushed through the gills by swimming; the megamouth shark and whale shark can suck or pump water through their gills. [6] Manta rays can time their arrival at the spawning of large shoals of fish and feed on the free-floating eggs and sperm. This stratagem is also ...
