Grub Lol, you described this so thoroughly that I could roll over and die laughing. August 21, at pm. Invertebrate Zoology, 7th edition. May 17, at am. New Zealand Journal of Geology and Geophysics.
Whale barnacles are species of acorn barnacle with specific habitat requirements that belong benefit; alternatively, some species may just increase the drag that the host experiences while swimming, making the barnacles parasites.
The barnacles are just along for the ride. They don't harm the whales or feed on the whales, like true parasites do. Barnacles don't serve any obvious advantage. What many people don't realize is that barnacles aren't actually parasites at all.

They are considered crustaceans. Barnacles and whales tend.
A Whale of a Ride For the entirety of the barnacles' lives they'll exist as diminutive hitchhikers on the backs and bellies of whales. However, the whale-riding barnacles enjoy a certain degree of protection from the mobility of their enormous bodyguards. Apparently they cause no harm to the whales, but they look like the must itch terribly. They typically attach to baleen whalesthough they may settle on toothed whales and, rarely, turtles, which have their own species of barnaclewhich split from whale barnacles in the Late Pliocene around 3.
Grey and humpback whales each have their own variety! We so often forget or choose to ignore!
Lawrence, humpback whales are known to have the most number of barnacles. Barnacles are crustaceans that attach themselves to a substrate—a. Although some barnacles are parasites, most are filter feeders.
What's on that whale WildWhales
Filter-feeding barnacles are the type that engage in symbiotic relationships with whales. The only trematode parasite known so far of sperm whales is the species. Such are the epizoic sessile barnacles Coronula diadema, C.
reginae and.
Also, I believe the author meant to say that gray whales may have up to pounds of barnacles on them, not humpbacks. The fleshy appendage exiting the hole—the "apertural shroud"—is more prominently displayed than in other barnacles.
Although some barnacles are parasites, most are filter feeders. Unbelievably, one healthy humpback whale was found to have kg of barnacles growing on it!
Coronulinae Leach Filter-feeding barnacles are the type that engage in symbiotic relationships with whales. Hosts also develop ways of getting rid of or protecting themselves from parasites.

The cyprid had circular eyes and, like other barnacles, had several oil cells in the head which probably acted as food reserves as cyprids do not feed. Though whale barnacles are generally considered to be commensals, callosities could be an adaptation to prevent barnacles from adding to drag by concentrating infestations, [22] and a heavy infestation may lead to eczema.
