Pseudorca crassidens | UAE National Red List of Mammals: Marine and Terrestrial
Taxa
Pseudorca crassidens | (Owen, 1846)
Asessment status in full
Data deficient
Assessment status abreviation
DD
Assessment rationale/justification
On the Gulf coast, the species is known from a small number of records of skeletal remains and strandings, whilst it has been reported off the east coast but not in recent surveys. There is insufficient information available on population size or trends of this species in UAE waters, hence it is assessed as Data Deficient. No regional adjustment is made to the Data Deficient assessment.

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.

History
Hornby (1966) considered the species to be Near Threatened, however, we consider DD to be the appropriate backcasted assessment for this species in 1996.
