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
Coronula diadema is a species of whale barnacle that lives on the skin of humpback whales and certain other species of whale. [2] This species was first described by Carl Linnaeus in the 1767 12th edition of his Systema Naturae .
On the gray whale, the barnacles embed themselves deeply in the skin and are mostly clustered on the animal's head and back. Crawling among the barnacles and taking advantage of the protection they provide are several species of ectoparasitic crustaceans known as whale lice , including the gray whale louse Cyamus scammoni and the generalist ...
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 ]
A humpback whale was spotted swimming with a severed tail off Washington. These sightings are now serving as reminders of the dangers of marine mammal entanglements and “ human carelessness ...

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 ...
