The smallspine spookfish (Harriotta haeckeli) is a species of fish in the family Rhinochimaeridae with a rather disjunct population.

[4] This species is named in honor of both the research vessel Ernst Haeckel, from which type was collected, and to the eminent zoologist Ernst Haeckel (1834–1919) for whom the ship was named.

[3][5] H. haeckeli is a small species compared to others in its genus and is coloured pale brown with darker shading on its underside.

[4] This species can be found off western Greenland, the Canary Islands, northeastern North America, Namibia, the southeastern Indian Ocean, Tasmania and southwestern New Zealand.

[4] It normally lives at depths greater than 1100 m.[1] This species is threatened by habitat loss.
