Dysalotus alcocki is a species of deep sea fish, a swallower, from the family Chiasmodontidae which is found in the tropical and temperate oceans around the world.

The adults fed mainly on fish.

[3] The juveniles and larvae are most frequently recorded from shallower waters[1] while adults are mostly caught from depths of over 1,000 metres (3,300 ft).

[2] The generic name is derived from the Greek dysalotos which means "difficult to catch"[2] and the specific name honours the English zoologist Alfred William Alcock (1859-1933).
