Last week’s louse species was Proechinophthirus zumpti Werneck, 1955 (Echinophthiriidae), a parasite of Brown Fur Seals, Arctocephalus pusillus (Schreber, 1775) (Otariidae). P. zumpti has a lot of variation in its setae (hair-like structures) on its body. The short, thick ones near the mouth look almost like hooks. I can imagine this louse is difficult to dislodge, which is good if your host is taking you on deep dives in the ocean!
These specimens were collected from A. pusillus seals (below) in the Great White Shark-infested waters off of Cape Town, South Africa. The specimens in these images are PSUC_FEM 10005362 (female), PSUC_FEM 10005347 (male), PSUC_FEM 10005368 (nymph). Here’s a photo of the host species, mid-dive:
