Overview
The halavi guitarfish is a critically endangered species of ray in the Glaucostegidae family. It is found in the Indo-West Pacific. It has only been recorded twice, in 1997 and 2004, in the levantine waters, the question of its permanent settlement in the Mediterranean Sea remains open. Its name is derived from the Arabic word حلاوي (halawi).
Glaucostegus halavi faces severe population declines primarily due to intensive fishing pressure across its range in the Western Indian Ocean. The species is particularly vulnerable to bottom trawling and gillnet fisheries that target demersal species in coastal waters. Habitat degradation from coastal development and pollution further compounds these pressures, while the species' slow reproductive rate limits its ability to recover from fishing mortality.
Habitat
This guitarfish inhabits shallow coastal waters, sandy and muddy bottoms, and continental shelf areas in the Western Indian Ocean. It typically occurs in depths ranging from nearshore waters to approximately 200 meters, preferring soft substrates where it can bury itself.
