sea louse
Salmon skin feeder
A sea louse is a small parasitic crustacean that attaches to fish, particularly salmon.
Sea lice feed on the skin, mucus, and blood of their hosts, causing damage that can be fatal in severe infestations.
They're a significant problem in fish farming, where crowded conditions allow populations to explode: The salmon farm struggled to control sea lice.
