HKScientists in Costa Rica may have identified a new species of ghost shark in the Pacific Ocean near Cabo Blanco and Cano Island. The species, tentatively named Rhinochimaera costaricana, exhibits distinct physical characteristics including a shorter snout, darker coloration, and a longer dorsal fin spine. Researchers note that while this species appears unique to the Central American coast, earlier specimens from Peru and Chile showed similarities, prompting ongoing comparisons. Genetic analysis suggests no reproductive contact with other ghost shark species. This discovery adds to a growing list of ghost shark species found globally, including recent finds in South Africa, Taiwan, Australia, Japan, and the Atlantic between Greenland and Brazil.
