Synodus saurus has been assessed as Least Concern.   This broadly distributed species is considered to be common in some localities, and expanding its range in others.  Although harvested as by-catch in localised regions of its range, this is not considered a major threat at present, and this species is unlikely to be undergoing any significant population decline.

Geographic Range [top]

Range Description:Synodus saurus is distributed in the eastern Atlantic around the Azores, Canaries, Madeira, and the continental waters off Morocco, and in the Mediterranean Sea (Sulak 1984).  In the western Atlantic, it is found only in the waters around the Bahamas, the Leeward Islands, and the West Indies (Russell 2002).

Population [top]

Population:Synodus saurus is regarded as a rare species in the Adriatic Sea, although there is circumstantial evidence that this species is expanding its range (Tutman et al. 2003).  Soares et al. (2002) report that this species is common around the Azores.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Synodus saurus can be found to depths of 250 m in the Canaries, but is most abundant at depths less than 50 m.  Synodus saurus is primarily associated with sandy substrates.  This species is a cryptic predator that feeds mainly on small, pelagic, gregarious fish, remaining camouflaged buried beneath the sand.  However, it is a highly mobile predator, capable of rapidly swimming more than five meters to capture its prey (Soares et al. 2002).

Threats [top]

Major Threat(s): Although not a target species, Synodus saurus is taken as by-catch during commercial trawling (Relini et al. 2000, Abdallah 2002).  However, this is not considered a major threat to this species at present, as it only occurs in localised regions of this species' range.

Conservation Actions [top]

Conservation Actions: There are no known species-specific conservation measures in place for Synodus saurus, however its distribution may cover a number of marine protected area designations, including the Florida Keys Marine National Park.   Monitoring of the harvest levels of this species is recommended.
