The whale barnacles are the acorn barnacles that belong to the family Coronulidae. . Whale barnacles and whales have a commensal relationship– the barnacle benefits at no benefit nor cost to the whale. However, callosities could be an. When Darwin got down and dirty with his work on Barnacles (), to untangle the relationships between deep-sea barnacle species.

In some situations, this barnacle coverage can actually act like a suit of armour. By rolling, they present the attacking whales with a back full of hard, sharp barnacles — a much tougher surface to penetrate. Have you seen grey or white patches of barnacles on whale skin?

It is not known exactly how young barnacles latch on to a whale in the middle of the ocean, but researchers think that whale skin may release a chemical cue that free-swimming larval barnacles are able to detect, somehow initiating the settling process.

Exactly how that cue works though is something that researchers are still trying to figure out. Living with lice Unlike barnacles, whale lice can only be transferred between animals through bodily contact.

These legs look similar to those of human louse, which is exactly where they got their name from. In the s, whalers noticed the small creatures and thought they looked and moved like human lice. They assumed they must be the same type of animal, only much larger, as they can grow up to 19mm in size.

Many mysteries still surround whale lice, but we do know they are highly specialized. Many types of whale lice can only be found on one species of whale. Grey and humpback whales each have their own variety!

While hitching a ride, these crustaceans munch on algae and whale skin. You may remember the juvenile humpback whale that fatally stranded on White Rock Beach last summer, its death attributed to the effects of fishing gear found entangled around its body. Although it is certain that the whale would have had lice on it before becoming entangled, the larger than expected population indicates the whale had been suffering the negative effects of the fishing equipment for some time.

In parasitism, only one species benefits from the relationship and causes significant harm to the other. Commensalism, in which only one species benefits without causing significant harm to the other, is the type of symbiosis between barnacles and whales.

Cementing the Relationship Barnacles begin their lives as free-swimming larvae, progressing through six larval stages. When they reach the last, or cyprid, stage, they settle onto the skin of a whale, where they complete their metamorphosis into juvenile barnacles. The juveniles -- tiny creatures resembling shrimp -- secrete cement that hardens into the hard, calcareous plates that surround them throughout their entire lives. As the cement plates meld together, the whale's skin is pulled into the spaces between the plates, permanently fusing the barnacles to the whale.

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. They derive two basic benefits from this commensalistic relationship.

As filter feeders, they depend on the availability of plankton, which they filter into their bodies through feather-like appendages extended through holes in their shells.

When the whales swim into plankton-rich waters to feed, so do the barnacles.

They are consistently carried from feeding to feeding. Protection from predators is another benefit. Barnacles attached to stationary objects often fall prey to fish, sea worms, starfish and snails. However, the whale-riding barnacles enjoy a certain degree of protection from the mobility of their enormous bodyguards.
