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. [1]
After hatching, whale barnacles go through six molting stages before searching for a host, being prompted to settle by a chemical cue from the host skin. The barnacle creates a crown-shaped shell, and in most instances, deeply embeds itself into the skin for stability while riding a fast-moving host. The shell plates are made of calcium ...
This barnacle has been found between January and March for several years in captive beluga whales in San Diego Bay, near a route used by migratory gray whales. The barnacles have evoked a skin reaction in the beluga whales resulting in the eviction of the barnacles, which suggests an immune response. [4]
Colloidal oatmeal has long been a home remedy for skin conditions like hives, since it has moisturizing and emollient benefits. Hwang suggests taking an oatmeal bath to treat hives. Mix a cup or ...
Xenobalanus globicipitis is a species of pseudo-stalked barnacle. [1] It is usually spotted on the appendages of at least 34 species of cetaceans , commonly baleen whales and bottlenose dolphins . This species is not technically a true stalked barnacle , hence the 'pseudo' in its name.
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 ...
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 themselves by means of a stalk.
Many parasites and epibiotics latch onto whales, notably whale lice and whale barnacles. Almost all species of whale lice are specialized towards a certain species of whale, and there can be more than one species per whale. Whale lice eat dead skin, resulting in minor wounds in the skin.
