Black ghostshark
species of chordates

The black ghostshark (Hydrolagus homonycteris), also known as the black chimaera, is a chimaera species within the family Chimaeridae. The species lives off the coasts of Australia and New Zealand, in the southwestern Pacific Ocean, in depths of 500–1,450 m (1,640–4,760 ft). It has a black or dark brown body; males have a total length of 108 cm (43 in). The species is closely related to the abyssal ghostshark. Although it is sometimes caught as a bycatch, it does not have any major threats and is listed as least concern by the International Union for Conservation of Nature (IUCN).
Taxonomy and etymology
The black ghostshark was described by Dominique A. Didier in 2008. It is one of 23 species in the genus Hydrolagus. Its genus name, Hydrolagus, comes from the Greek words hydro, which means "water" and lagos, which means "hare". The specific name, homonycteris, is composed of the word homo, the Latin word for man, and nycteris, the word for bat. Its name was taken after Thomas A. Griffiths, a professor at Illinois Wesleyan University, whose students called him "bat man".
Begin with the source’s own compact description: “Black ghostshark” is species of chordates. The dossier treats that line as a proposition to test through Black, ghostshark and species, not as a finished interpretation.
Why this record matters
The phrase “species of chordates” 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.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Feb 15, 2026. The linked authority identifier is Q2561377. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2008.
A general summary may omit uncertainty, sample limits or methodological disagreement that is explicit in the technical record. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
