Arabian toothcarp
species of fish

The Arabian toothcarp (Aphaniops dispar), known also as the mother-of-Pearl fish is a species of killifish belonging to the family Aphaniidae . It can be found from the shores of the Red Sea south to Ethiopia, the Gulf of Aden, the Arabian Sea and along the Persian Gulf east to Pakistan and India. It is also found in the Suez Canal, the northern coast of the Sinai Peninsula, and in one location on the Israeli coast. The former recognized subspecies: A. d. richardsoni, the Dead Sea toothcarp endemic to the Dead Sea has now been raised to a full species as Aphaniops richardsoni.
Taxonomy
The Arabian toothcarp was reassigned from the genus Aphanius in 2020 in the course of a reclassification of several species in that genus.
Description
A. dispar is a chubby and robust fish in both sexes with a similar body plan lacking any spines, but here is where their similarities end. This species expresses extreme sexual dimorphism in both appearance and behaviour. The larger males are very brightly coloured with long fins that may reach the end of the tail when lowered. He is a lustrous greyish blue with bright silver spots spread across his body, with a relatively sharp snout.
Begin with the source’s own compact description: “Arabian toothcarp” is species of fish. The dossier treats that line as a proposition to test through Arabian, toothcarp 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.
The date and method of observation matter as much as the stated conclusion, especially where classification or consensus has changed. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q1070773. None of the 0 selected statements returned an explicit reference. The first chronological checks are 2020.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. 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.
