Caligus infestans is a species of sea louse in the family, Caligidae, first described by Camill Heller in 1865.
In Australia it is found as an ecto-parasite (a parasite living on the outside of its host) of fishes at depths of 200 metres in the following IMCRA zones - Central Eastern Shelf Transition (39), Northeast Shelf Province (40), and the Northeast Shelf Transition - that is, in seas off the north east coast of Australia.
A search of the Smithsonian Invertebrates Collection reveals they have also been found off:
the Greater Sunda Islands (host - Scomberomorus commerson) USNM 180506 Phuket (host - Scomberomorus commerson) USNM 180517 Indian Ocean (host - Scomberomorus commerson) USNM 180518
and Madagascar and Mozambique (all with the same host).
