Overview

Comprehensive Description

Biology

Inhabits sandy weedy areas of coastal reefs (Ref. 9710). Lives in open muddy substrates in estuaries as well as deep coastal bays. Usually found lining up with ropes, seawhips and large stringy-type sponges. Incredible mimic that may float over the open bottom like a mangrove-shoot, may stand on its head (Ref. 48637). Enters mangroves (Ref. 9710).

Justification
Anacanthus barbatus has been assessed as Least Concern. Despite being of minor commercial importance as a food source, this threat is not known across this species entire, broad distribution and is not considered to a have a significant impact on population numbers at present. In addition, this species is known from a range of habitat types and so is unlikely to suffer significant declines as a result of threats to a particular habitat type.

Threats

Threats

Major Threats
Anacanthus barbatus is of minor commercial importance (FAO 2001b), and so is not likely to be undergoing a significant population decline.

This species may also be impacted by habitat degradation caused by coastal development, however this is only a localised threat and because this species is found in a number of different habitat types this is not considered a major threat.
