Species
Taxon distribution as listed in assessment
This species generally lives in deep water and is apparently relatively common off the east coast of the UAE. There are no confirmed occurrences in the Arabian Gulf where the habitat is not suitable as this is a deep-water species (Baldwin 2005). Globally, this is a widely-distributed species, inhabiting deep waters of the continental slope and outer shelf, from the tropics through the temperate regions in both hemispheres (Taylor et al. 2012a).

Habitat
Habitat details as listed in assessment
This is a deep-water species, diving for squid and fish over underwater canyons and at the edge of the continental shelf to depths probably exceeding 1,000 m (Baldwin et al. 1999, Baldwin 2005).
Is there a map available in assessment?

Assessment rationale/justification
Although the species is said to be relatively common off the east coast, no information is available on population size or trends. There are also no data on threats to the species, hence it is assessed as Data Deficient. No regional adjustment is made to the Data Deficient assessment.

Conservation
Threats listed in assessment
The main threats to cetaceans in UAE waters include: incidental mortality in trawl, drift and anchored gill nets, depletion of prey populations (due in part to commercial overfishing); ship and boat strikes, disturbance due to underwater noise (including that from vessel traffic, drilling, piling, military operations and seismic activity related to offshore oil and gas exploration). Inshore and shallow-water species are further potentially threatened by entanglement in abandoned fishing gear, coastal development including port and harbour construction, dredging, land reclamation, residential and tourist development, and pollution (especially hydrocarbons). A lack of information (e.g. population size and trend, the location of critical habitats, and feeding ecology) hinders the development of appropriate conservation actions, but this should be used as an excuse for inaction.

Further information
History
Hornby (1996) assessed the species as Near Threatened. It is not clear what criteria would have been used in 1996, but likely to have been assessed under criteria different than those currently applied by IUCN, and we consider that the species would also have been Data Deficient in 1996.
