This is an ectoparasite that lives exclusively on humpback whales. The infestation is most concentrated around the genital apertures, but occurs on all parts of the body, most commonly where there is an infestation of the barnacle species Coronula diadema.[2]

These lice will promptly try to attach themselves to people when handling whales during processing.[2]

Description

Males of the species grow to about 11.5 mm long and 4 mm wide, with the first antenna being about 5.25 mm long.[2] Females grow to 9.5 mm long and 4 mm wide with the first antenna 3.5 mm.[2]

Both sexes have four-segmented antennae, the endmost containing strong bristles. The body comprises multiple segments, each containing hooks used to attach itself to the whale.[2]

gollark: Technically at least the giannis and diode cults existed beforehand.
gollark: I have a bunch of random Game of Life implementations sitting around, mostly as tests for things.
gollark: If I'm correct it should eventually start building a diagonal road off somewhere, forever.
