New Ghost Shark Species Discovered Near Costa Rica

Costa Rican scientists have reported the possible discovery of a new species of ghost shark (family Dalatiidae) in the Pacific waters off Cabo Blanco and Cano Island. The specimen was collected during a routine survey by the National Institute of Biodiversity and Ecosystem Conservation and exhibits distinct morphological features that differ from known ghost shark species, prompting preliminary classification as *Dalatias* sp. nov.

The team, led by marine biologist Dr. Ana Morales, noted that the shark’s body shape, fin placement, and dermal denticle pattern are unlike those of the common *Dalatias licha*, the only other ghost shark recorded in the region. Genetic analysis of tissue samples is underway to confirm the taxonomic status, while researchers plan additional dives to assess the population size and habitat preferences of the putative new species. This finding adds to the growing recognition of the Pacific coast of Costa Rica as a biodiversity hotspot for elasmobranchs.

If confirmed, the discovery would expand scientific knowledge of deep‑water shark diversity and underscore the importance of protecting the marine ecosystems surrounding Cabo Blanco and Cano Island. The research team will publish their full findings in a peer‑reviewed journal later this year, providing a foundation for future conservation and management strategies in the area.
