The lice predominantly eat algae that settle on the host’s body. They usually feed off the flaking skin of the host and frequent wounds or open areas. They cause minor skin damage, but this does not lead to significant illness. The development of the whale louse is closely connected with the life pattern of whales.
Big Batches of Barnacles 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 to the whales, but they give helpful lice a place to hang onto the whale without getting washed away by water.

Is it good to remove barnacles from turtles?
Parasitic Organisms. All barnacles increase surface drag and decrease the overall hydrodynamic shape of the turtle. Barnacles can be pried off with a variety of tools, but care should be taken with those that have damaged the shell. These should be removed with care so as to not create further injury.
What eats a barnacle?
Barnacles are suspension feeders feeding on plankton whilst some species are parasites. Their predators include worms, marine snails (e.g. whelks), sea stars, some fish and some shorebirds. They also need to compete for scarce living space with limpets, mussels and other barnacles.

How big are whale lice?
5 to 25 millimetres
Why are barnacles bad?
Barnacles are related to crabs and lobsters. They attach themselves permanently to a hard substrate. These barnacles can either cause minimal stress such as increase surface drag and impede the movement of the turtle, or more serious with damage to shell causing bacterial or fungal infections to enter.
Why do Whales have stuff growing on them?
The callosities themselves are actually grey; their white appearance is due to large colonies of lice, barnacles and parasitic worms that reside on them.

Would a whale eat a human?
Whales, in general, are not capable of swallowing a human being and therefore will not eat you. A sperm whale does have a large esophagus that is capable of swallowing large mammals, but its primary food source is fish and large squid and octopus found in the deep, so you might think of sperm whales as dangerous.
Can whales bite?
