Multipore searsid
species of fish
The multipore searsid (Normichthys operosus) is a species of fish in the family Platytroctidae (tubeshoulders).
Name
Its scientific name is from the Latin operōsus, "busy, hardworking".
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.
Description
The multipore searsid is maximum 16.4 cm (6.5 in) long and is black or dark brown in colour. 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".
Habitat
The multipore searsid is bathypelagic, living in Atlantic Ocean at depths of 780–5,000 m (2,560–16,400 ft), but rarely going below 1,000 m (3,280 ft), following a 4 °C (39 °F) isotherm and being found near seamounts. It is most concentrated in the waters southwest of Ireland.
Begin with the source’s own compact description: “Multipore searsid” is species of fish. The dossier treats that line as a proposition to test through Multipore, searsid and species, not as a finished interpretation.
Why this record matters
The phrase “species of fish” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Datasets, specimens, observations and peer-reviewed methods provide the appropriate test for the technical claims summarized here. The source revision retrieved here is dated Apr 8, 2026. The linked authority identifier is Q2097794. None of the 0 selected statements returned an explicit reference.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
