Around 7,500 whale lice live on a single whale. [3] With some species of whale louse, whale barnacle infestations play an important role. On the right whale, the parasites live mainly on callosities (raised callus-like patches of skin on the whales' heads). The clusters of white lice contrast with the dark skin of the whale, and help ...
The callosities themselves are grey, but their white appearance is due to large colonies of whale lice, whale barnacles and parasitic worms which reside on them. [5] [6] Young whales and diseased individuals are often infested with a different species of cyamid, which gives the callosities on those whales an orange hue rather than white. [7]
Gray whale rostrum covered in the endemic Cryptolepas rhachianecti barnacles and cyamids often called whale lice. Whale barnacles typically attach to baleen whales and have a commensal relationship–the barnacle benefits and the whale is neither helped nor harmed. [3] A single humpback whale may carry up to 450 kg (990 lb) of barnacles. [21]
The first spade-toothed whale bones were found in 1872 on New Zealand’s Pitt Island. Another discovery was made at an offshore island in the 1950s, and the bones of a third were found on Chile ...
Lice in this family have a chaetotaxy characterized by three kinds of setae: spines, scales, and hairs. Different species have different arrangements of these setae. Species also have various egg-laying habits, with some laying them singly or in clusters, and some cementing them to the hairs of the host animal. [2] These lice have antennae but ...
Marine biologists have captured a rare sight of a giant pod of over 1,500 dolphins leaping and swimming off the California coast.. The “super pod” of Risso’s dolphins was spotted in Carmel ...
New England scientists spotted North Atlantic right whale Snow Cone just south of Nantucket on Sept. 21. What they saw is "gut wrenching." A whale and species on the brink.
Atlantic gray whale Population of the gray whale (Eschrichtius robustus) North Atlantic Ocean and Mediterranean Sea: Last recorded in 1760. The same species survives on the Pacific Ocean. [43] A single individual, presumably dispersed over the Arctic, was observed off Florida in 2023 and Nantucket, Massachusetts in 2024. [44]
