Taxonomic notes

Chaetodon tinkeri is here defined as comprising the Hawaiian, Johnston Atoll and Raratonga populations. The taxonomic status of populations recorded from areas in the western parts of the range needs further taxonomic research.

      Justification

      The species is common and fairly widespread. Although it is occasionally collected  for the aquarium trade, its deep water habitat likely prevents the harvest of many specimens. Therefore, harvesting does not appear to be a major threat and there are no signs of significant decline. It is listed as Least Concern.

      Range Description

      This species is known only from a few locations in the central Pacific Ocean including the Hawaiian Islands (USA), Johnston Atoll (USA), and the Marshall Islands (Enewetak Atoll). It is presumably more widespread, but remains undetected because of its preference for deep water (G.R. Allen pers. comm. 2006). It ranges from 6-160 m in depth, but is usually found from 30-160 m, being  most abundant at ca 122 m (R. Pyle pers. comm. 2009).

      Description

      It is relatively common with stable populations (G.R. Allen pers. comm. 2006). There are localized periodic declines in some specific areas due to collection for the aquarium trade (R. Pyle pers. comm. 2009). However, this does not affect the global population.

      Habitat and Ecology

      Inhabits outer reef slopes and drop-offs. Feeds on crabs, worms, and other invertebrates; forms pairs (Pyle 2001). Often found in the vicinity of steep slopes, solitary or in pairs and occasionally in small aggregations (Allen 1980).

      Threats

      There appear to be no major threats to this species. Colletion is limited and is not considered to be impacting the global population.

      Use and Trade

      The species is occasionally exported through the aquarium trade (Pyle 2001). It is a high priced aquarium export at around $ 250 per individual, a consequence of the difficulty in collecting this species from its deepwater habitat (R. Pyle and L. Rocha pers. comm. 2009).

      Conservation Actions

      In-place land/water protection

      • Occurs in at least one protected area : No

      Conservation Actions

      There appear to be no species-specific conservation measures in place (G.R. Allen pers. comm. 2006). It is likely not within any protected areas due to its depth range, although this needs verification.
