It was both swimming and leaping so the timing may not be an accurate swim speed. Nevertheless, it’s the most reliable speed trial of a fish achieved so far. The species is 42 recognised by the huge dorsal fin that can be erected, like a sail, in order to frighten and round up fish. The fin folds into a groove when the fish is travelling at speed, and when hunting its body changes from a dull colour to iridescent silvery-blue stripes. Several sailfish might work together to corral a bait ball, flashing their dorsal fins to tighten the ball, before shooting in and whipping their heads from side to side, slashing and maiming the smaller fish to be gobbled up on the next run.
When it is searching for prey in the ocean overhead, the eyes point upwards, and when it is feeding, the eyes rotate to face forwards. Two structures above the small, pointed mouth, which look like tiny eyes, are actually nostrils. The fish is thought to be partly a kleptoparasite in that it probably steals prey from other creatures, such as 10m (33ft) long, colonial, jellyfish-like animals called siphonophores that float about in the deep sea like living drift nets. The barrel-eye manoeuvres carefully among the siphonophore’s tentacles, the transparent shield protecting its eyes, and steals copepods and other small crustaceans the creature has trapped.
61 Blob sculpin The deep-sea pelican eel Eurypharynx pelecanoides is a swimming mouth. Its enormous maw is far wider than its long and slender metre-long body. The lower jaw is like a pelican’s pouch, hence the common name, and it is loosely hinged so the pelican eel can catch and eat fish considerably larger than itself. But it is something of an enigma. Eel stomachs tend to be filled with deep-sea crustaceans, small fish and squid rather than large fish, and it has a curious organ on the tip of its tail that has all the trappings of a lure, which glows pink with occasional flashes of red, but at the wrong end of its body!
