Name
Its scientific name is from the Latin operōsus, "busy, hardworking".[6]
Its common name "multipore" refers to the dermal pits located behind its shoulders, and "searsid" is a name used for fish that resemble Searsia koefoedi.[7]
Description
The multipore searsid is maximum 16.4 cm (6.5 in) long and is black or dark brown in colour.[8][9] Its body is deep and compressed, its head about one-third of body length. It has a simple lateral line and few or no photophores. It has two to four large, and several smaller, open dermal pits behind the upper part of shoulder girdle, with usually at least one pit twice as wide as body scales; these give it the name "multipore."[10][11]
