Asterocheres lilljeborgi is a species of copepod in the family Asterocheridae. It is found in the British Isles and Scandinavia where it is a semi-parasite of starfish. First described as Asterocheres lilljeborgi in 1859 by the Norwegian marine biologist Jonas Axel Boeck, [1] it is the type species of the genus. [2]

Distribution

The species is found in west and south Norway, south-western Sweden, the Skagerrak, the North Sea, around the coasts of England and northern France as well as the Davis Strait, the Aleutian Islands and Alaska. [1]

Ecology

A. lilljeborgi is associated with starfish, such as the bloody Henry starfish (Henricia oculata) or the blood star (Henricia sanguinolenta). [3] Some 90% of the starfish examined were parasitised. [4]

Tantulocarida is a highly specialised group of parasitic crustaceans that consists of about 33 species, treated as a subclass of the class Hexanauplia. They are typically ectoparasites that infest copepods, isopods, tanaids, amphipods and ostracods.

Siphonostomatoida Order of crustaceans

Siphonostomatoida is an order of copepods, containing around 75% of all the copepods that parasitise fishes. Their success has been linked to their possession of siphon-like mandibles and of a "frontal filament" to aid attachment to their hosts. Most are marine, but a few live in fresh water. There are 39 recognised families:

Deoterthridae is a family of crustaceans in the subclass Tantulocarida, classified under the class Maxillopoda. It contains the following genera: It has been accepted as Cumoniscidae by the World Register of Marine Species.

Cyclopoida Order of crustaceans

The Cyclopoida are an order of small crustaceans from the subclass Copepoda. Like many other copepods, members of Cyclopoida are small, planktonic animals living both in the sea and in freshwater habitats. They are capable of rapid movement. Their larval development is metamorphic, and the embryos are carried in paired or single sacs attached to first abdominal somite.
