Kingdom Phylum Class Order Family
Animalia Chordata Actinopterygii Perciformes Labridae

Scientific Name: Bodianus dictynna
Species Authority: Gomon, 2006
Taxonomic Notes: For taxonomic treatment see Gomon (2006). Bodianus dictynna was long thought to be conspecific with B. diana but the two are separable on colour pattern (B. Russell pers. comm.. 2008).

Assessment Information [top]

Red List Category & Criteria: Least Concern ver 3.1
Year Published: 2010
Date Assessed: 2008-03-12
Assessor(s): Russell, B.
Reviewer(s): Sadovy, Y. & Carpenter, K.E.
Justification:
Little is known of population and life history characteristics, but inferred Least Concern is because of widespread distribution in the western Pacific where it is still common, despite being taken by aquarium collectors.

Geographic Range [top]

Range Description:This species is found from the eastern coasts of the Indo-Malaysian Archipelago to Japan, Palau, western Micronesia, Samoa, Tonga and southeastern Australia. It is excluded from the Indian Ocean, except for offshore islands of northwestern Western Australia and the southern coasts of eastern Indonesia, west to about Java. It is also reliably reported from Sagami Bay, Japan, western edge of Micronesia, Samoa, Tonga, New Caledonia and Montague Island, New South Wales, Australia. Although known from Kwajalein in the Marshall Islands, it rarely occurs on the central Pacific geologic plate (B. Russell pers. comm. 2008).

Habitat and Ecology [top]

Habitat and Ecology:A moderately small species, to about 144 mm SL. Individuals are usually found at depths of 9-30 m. The species is almost always associated with living coral reefs. Juveniles are often found near black coral and gorgonians (Myers 1989).
Systems:Marine

Use and Trade [top]

Use and Trade: This species is utilized as aquarium fish (juveniles). Moderately valuable species (US$10-15 per fish) in Australia (reported as B. diana, Ryan and Clarke 2005).

Threats [top]

Major Threat(s): Degradation of coral reefs from climate change and coastal development are possible major threats.
