Whale lice attach themselves to the host body in places that protect them from water currents, so they can be found in natural body openings and in wounds; with baleen whales they are found primarily on the head and in the ventral pleats. Around 7,500 whale lice live on a single whale. [3]
This would make the relationship between whale barnacles and certain whales mutualistic in which both parties benefit. It may be that some baleen whales, in the context of the fight-or-flight response, are adapted for a fight response, namely the humpback and gray (Eschricthius robustus) whales.

The skim-feeders are right whales, gray whales, pygmy right whales, and sei whales (which also lunge feed). To feed, skim-feeders swim with an open mouth, filling it with water and prey. Prey must occur in sufficient numbers to trigger the whale's interest, be within a certain size range so that the baleen plates can filter it, and be slow ...
Narwhal diet varies between seasons. In winter, narwhals feed on demersal prey, mostly flatfish, under dense pack ice.
