It occurs around the edges of continental and insular shelves at a depth of , typically on or near mud bottoms. One of the smallest living shark species, the pygmy ribbontail catshark grows to a maximum known length of . It has a slender body with a low, ribbon-like tail fin, and is dark brown in color with blackish dorsal fin markings and tail bands.

It is of minimal significance to fisheries, being caught as bycatch in some areas.
==Taxonomy==
The first known specimens of the pygmy ribbontail catshark were collected during the 1907–1910 Philippine Expedition of the U.S. Fish Commission Steamer ''Albatross''. Hugh McCormick Smith, Deputy Fish Commissioner and director of the expedition, published a description of this shark in a 1913 issue of the ''Proceedings of the United States National Museum'', naming it for the expedition's General Assistant and Naturalist Lewis Radcliffe, and creating for it the new genus ''Eridacnis''. The type specimen is a long adult female caught off Jolo Island in the Sulu Archipelago, Philippines.
