BBC Life episode 4: Fish. Highlights: flying fish, the sarcastic fringehead, mudskippers, rock climbing gobies in Hawaii, and pretty much everything in this episode. Next up, episode 8: Creatures of the Deep.

UPDATE on episode 8: With a title like “Creatures of the Deep,” I thought it was going to focus on anglerfish and all the weird things that live in perpetual darkness. This episode is actual about marine invertebrates. Highlights: the fried egg jellyfish, Humboldt squid, cuttlefish (one of my faves), coral battles, etc.
