Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
This nocturnal species inhabits a substrate of sand and rock, or occasionally mud (Holthuis 1991, Bianchi et al. 1999). It shelters during the day and forages at night, feeding mainly on bivalves (Lavalli et al. 2007). There are reports of this species occurring at depths of up to 300 m, although it is most commonly found between 5 to 70 m. This species can reach up to 32 cm in total length but usually is not more than 25 cm (Holthuis 1991, Bianchi et al. 1999).

Justification
Scyllarides herklotsii has been assessed as Data Deficient. This species is harvested for food throughout its range, although harvest levels are unknown therefore making an evaluation of stock status impossible. Further research into threat and population information, and the levels of harvesting, is necessary before a more accurate assessment of the conservation status can be carried out.

Conservation Actions

Conservation Actions

There are no species-specific conservation measures in place for this species.

A decline in global captures of Scyllaridae has been documented, although information on specific species is lacking (Spanier and Lavalli 2007). Further research is necessary to determine the impact that global harvesting is having on specific species, and to clarify if the documented decline is due to reduced populations or simply reduced effort.

Wikipedia

Scyllarides herklotsii

Scyllarides herklotsii is a species of slipper lobster from the Atlantic coast West Africa. It is edible, but is not commercially fished, and is taken only by accident.[3]

S. herklotsii was named in 1851 by Jan Adrian (or Janus Adrianus) Herklots in a doctoral thesis at the University of Leiden;[4] the type material came from Butre, Ghana,[3] and is stored at the Dutch Nationaal Natuurhistorisch Museum.[5] The species is found from Senegal, where its range overlaps slightly with that of Scyllarides latus, south to Ponta do Pinda, Angola. It usually lives at depths of 5–70 metres (16–230 ft), but has been recorded from depths as great as 200 m (660 ft).[3] It prefers sandy and rocky substrates.[3]

Scyllarides herklotsii reaches a total length of 32 centimetres (13 in), but does not generally exceed 25 cm (9.8 in) long.[3] It may be differentiated from S. latus by the lower, more rounded nature of the tubercles on the carapace.[3]
