Kingdom Phylum Class Order Family
ANIMALIA CHORDATA CHONDRICHTHYES CARCHARHINIFORMES SCYLIORHINIDAE

Scientific Name: Galeus springeri
Species Authority: Konstantinou & Cozzi, 1998
Taxonomic Notes: This is a member of the Galeus arae complex of the western Atlantic. The taxonomy of this complex was recently revised with former subspecies now listed as full species (Konstantinou and Cozzi 1998, Konstantinou et al. 2000), which is generally accepted. This species was previously known as Galeus arae antillensis (in part).

This species is morphologically varied and sometimes difficult to distinguish from other members of the G. arae complex. It is however, separated from its congeners by the combination of the presence of a ventral precaudal crest of enlarged denticles, colour pattern and vertebral counts (Konstantinou and Cozzi 1998). It occurs sympatrically with G. antillensis.

Justification:
Galeus springeri is a member of the western Atlantic Galeus arae species complex. Information for this species is currently limited but it appears to have a relatively restricted distribution in the western central Atlantic (Cuba, Jamaica, Hispaniola, Puerto Rico and the Lesser Antilles). Its distribution may not be completely documented due in part to confusion with its congeners. This species is found in depths of 457–699 m and reaches a maximum size of at least 48 cm total length, but virtually nothing known of their biology. This species is a potential bycatch of demersal trawl fisheries, but very little information is available on fisheries operating within its bathymetric range at present. Insufficient information is available to assess this species beyond Data Deficient at this time. Monitoring of fishing pressure within this species’ apparently limited geographic and bathymetric range is required. Research is also needed on its life-history parameters, abundance, range and capture in fisheries (if any).

Geographic Range [top]

Habitat and Ecology [top]

Habitat and Ecology: A deepwater species of the upper continental and insular slopes at depths of 457–699 m (Konstantinou and Cozzi 1998). Little known about its biology. Although the reproductive mode of this species had been in question, Konstantinou et al. (2000) reported this species as oviparous. Parsons (1986) reported on oviparity in Galeus arae antillensis off Puerto Rico, where G. antillensis occurs sympatrically with G. springeri and so it is not known which species his specimens belonged to. Reaches a maximum size of at least 48 cm TL (largest verifiable record in the literature; McLaughlin and Morrissey 2004).
Systems: Marine

Threats [top]

Major Threat(s): Uncertain. Any future expansion of deepwater demersal trawl fisheries in the species’ restricted range may be cause for concern and would require monitoring. Its small size would preclude it from capture in some fishing gear.
