A rare benthic ray with a restricted distribution in the Western Central Atlantic. The Florida torpedo is known from only two specimens (the types; 16 and 22 cm total length) taken at 229 m on the upper continental slope on the western edge of the Grand Bahama Bank, and a photographic record of an individual amongst coral at 11 m from Grand Cayman Island. With these limited records, essentially nothing is known of its biology. Potentially a bycatch of demersal trawl fisheries, although no information available on the possible extent of such fisheries. Presently assessed as Data Deficient until further specimens and data become available, but potentially of conservation concern due to restricted range and apparent rarity.

Habitat and Ecology [top]

Habitat and Ecology:Demersal species with one individual observed at 11 m around coral in Grand Cayman and two specimens (16 and 22 cm TL) taken from the upper slope on the western edge of the Grand Bahama Bank at a depth of 229 m (Bullis 1962, McEachran and Carvalho 2002).

Threats [top]

Major Threat(s): No information available, but may be a limited bycatch in demersal trawl fisheries.

Heavy development and tourism pressure exists on coral reef habitats around Grand Cayman Island (Burke and Maidens 2004).

Conservation Actions [top]

Conservation Actions: None in place for this species. Its occurrence and distribution needs to be better defined, as does interactions with any fisheries in the area.

Coral reef habitat around Grand Cayman is managed under a Marine Protected Area zoning plan (Burke and Maidens 2004).

The development and implementation of management plans (national and/or regional e.g., under the FAO International Plan of Action for the Conservation and Management of Sharks: IPOA-Sharks) are required to facilitate the conservation and management of all elasmobranch species in the region.
