The best of the recent black and white illustrations:

A frogfish.
They move around on their fins like they're part walking, part hopping along the ocean floor. They're also related to anglerfish and are ambush predators with a lure on their head.

A Pacific spiny lumpsucker.
These guys always remind me of muppets. A very cute fish. Their disk shaped ventral fin lets them hold onto rocks in high tide areas.

A wolf eel.
Not truly an eel—they have pectoral fins—these guys have some brilliant orange and brown colors with blue-green eyes as babies and then turn into grey, spotted, heavy-jawed animals as adults.
