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]
Whale barnacles on a humpback whale. Most barnacles are encrusters, attaching themselves to a hard substrate such as a rock, the shell of a mollusc, or a ship; or to an animal such as a whale (whale barnacles). The most common form, acorn barnacles, are sessile, growing their shells directly onto the substrate, whereas goose barnacles attach ...
The species is now only known from the northern Pacific Ocean where gray whales are found. The gray whale was present in the northern Atlantic Ocean between the Late Pleistocene and recent times, and C. rhachianecti fossils have been found on a beach in the Netherlands, showing that the barnacle must also have been present.

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 .
Rafting species live either attached to neustonic organisms (e.g. barnacles that settle on Janthina shells) or inanimate debris. Some rafting species have evolved to live on debris at the ocean's surface, such as the smooth gooseneck barnacle Lepas anatifera , while others may be coastal species that settle on near-shore floating debris and are ...
Killer whales play an important role in our ocean's ecosystem. Female orcas can live up to 90 years, and male orcas live up to 60 years. Whales can communicate through sounds ranging from clicks ...

Group of buoy barnacles attached to a float they constructed themselves. The buoy barnacle (Dosima fascicularis) is a species of goose barnacle known for its unique characteristic of hanging downwards from a floating appendage which drifts at the water surface and is carried along by ocean currents.
