Justification
This species is circumtropical, and may be common in some parts of its range. It is found in shallow waters, and is collected in some parts of its range. Its population is probably not undergoing widespread decline globally, but the taxonomy of the species needs revision, as it is probably a complex. It is listed as Data Deficient. More research is needed on this species' taxonomy, biology, and the potential impact of fisheries.

Habitat and Ecology in detail

Habitat and Ecology
This species is found under stones in Cuba, whilst in the Caribbean region it occurs in coral debris and sand flats (Bruckner 2006). In Comoros, the species is intertidal and burrows in the sand between corals and stones (Samyn et al. 2006). This species is quite small, and is probably cryptic.

No information is known on changes of habitat requirements during the life history of the species, but generally, the juveniles of aspidochirotids are cryptic and small individuals may migrate into adult habitat later (Purcell 2004).

Threats

Use trade
This species is opportunistically fished throughout its range when other species are depleted. It is of commercial importance in China (Choo 2008), Nicaragua (Toral-Granda 2008), Madagascar (Rasolofonirina 2007), and the Philippines.

Threats in detail

Threats
Although not one of the most important species (low value) for fishery purposes, it can be expected that this species may become more popular after the depletion or reduction of other species of higher commercial importance and value.

Many sea cucumbers are broadcast spawners, which can limit the fertilization success of a species in exploited populations.
