The whale shark (Rhincodon typus) is a slow-moving, filter-feeding carpet shark and the largest known extant fish species. The largest confirmed individual had a length of 18.8 m (61.7 ft). [8] The whale shark holds many records for size in the animal kingdom, most notably being by far the most massive living non-cetacean animal.
As with residents and transients, the lifestyle of these whales appears to reflect their diet; fish-eating orcas off Norway have resident-like social structures, while mammal-eating orcas in Argentina and the Crozet Islands behave more like transients. [118] Orcas of the same sex and age group may engage in physical contact and synchronous ...
At least 15,000 whales are estimated to inhabit the North Atlantic. [35] In the Northeast Atlantic, two orca ecotypes have been proposed. [36] Type 1 orcas consist of seven haplotypes and include herring-eating orcas of Norway and Iceland and mackerel-eating orcas of the North Sea, [36] as well as seal-eating orcas off Norway.
Hungry sharks have descended on a 70,000-pound whale that died along Florida’s Gulf Coast, proving authorities were wise to tow it 15 miles out to sea. ... Eating Well. The #1 no-added-sugar ...
The animal faced competition from whale-eating cetaceans, such as Livyatan and other macroraptorial sperm whales and possibly smaller ancestral killer whales .
