Comoro cat shark

<em>Scyliorhinus comoroensis</em>, the Comoro catshark, is a small demersal shark in the family Scyliorhinidae. As its name suggests, it is associated with the waters around the Comoro Islands in the western Indian Ocean, where it was first described from specimens collected in the region. Like other catsharks, it is a bottom-dwelling species adapted to life on or near the seafloor, typically inhabiting continental and insular shelf and slope environments. Biological traits including average lifespan, body length, body weight, and dietary preferences remain poorly documented due to the species' limited range and the scarcity of specimens available for study. Based on comparisons with related scyliorhinid species, it likely feeds on small fish, cephalopods, and invertebrates. The species is currently assessed as Data Deficient by the IUCN, reflecting the limited information available on its distribution, population size, ecology, and response to potential threats such as bycatch in artisanal and commercial fisheries operating in the Comoros region. Dedicated surveys and additional specimen collection are needed to improve knowledge of <em>Scyliorhinus comoroensis</em> and to determine appropriate conservation measures.
