Overview

Distribution

Range Description

This species is distributed in the Indo-West Pacific region. It is known from southeast Africa: Inhambane in Mozambique to Cape Province in South Africa (24º to 34º50'S) (Holthuis 1991). There is some evidence it may also occur further west along the Cape Province coast (A. Cockcroft pers. comm. 2009).

The type for this species is Port Elizabeth in Cape Province, South Africa (Holthuis 1991).

Habitat and Ecology
This species has a depth range of 37 to 380 m, but is most commonly found in depths of less than 100 m (Holthuis 1991). It inhabits a substrate of mud, or fine sand into which it digs (Holthuis 1991), but also found on deep-reef fringes, and light foul ground (A. Cockcroft and A. MacDiarmid pers. comm. 2009). This species shelters during the day, and forages at night, feeding mainly on a diet of bivalves (Lavalli et al. 2007).

Justification

Scyllarides elisabethae has been assessed as Least Concern. It occupies a sizeable range and occurs on a variety of substrates, but mainly mud and sand. Although there may have been localised declines, the ecological characteristics of slipper lobsters make them resistant to extinction as they need not aggregate to spawn, and are highly fecund with well connected populations via long-lived larvae. The landings are largely a result of incidental trawl and trap by-catch, or by divers.
