Taxonomy [top]

Kingdom Phylum Class Order Family
Animalia Chordata Chondrichthyes Carcharhiniformes Scyliorhinidae

Scientific Name: Atelomycterus baliensis White, Last & Dharmadi, 2005
Common Name(s):
English Bali Catshark
Taxonomic Notes: This is a recently described species (described in 2005 by White, Last & Dharmadi). It probably gets confused with Atelomycterus marmoratus which is more widespread in the region and co-occurs off the island of Bali.

The Bali Catshark (Atelomycterus baliensis) is a relatively small catshark, recently described from Bali. This species is known only from off Jimbaran Bay in southern Bali and apparently has a very restricted range, as it has not been recorded during extensive surveys at localities on neighboring islands (e.g., Lombok). It is caught irregularly by demersal fishers off the island of Bali and is retained. Presumably it is a reef-dwelling species and thus is likely to be adversely affected by dynamite fishing which is common in this region. The Bali Catshark's extent of occurrence is estimated at less than <20,000 km². A continuing decline in the area, extent and quality of its habitat, as well as the number of individuals, is inferred as a result of destructive fishing practices within its range, warranting an assessment of Vulnerable. If further surveys locate this species from other areas then this assessment would need to be revisited.

Geographic Range [top]

Range Description:Endemic to Bali. Known only from off Jimbaran Bay in southern Bali (White et al. 2006). Possibly has a very restricted range, with an estimated extent of occurrence potentially limited to <20,000 km², as none have been recorded during extensive surveys at localities on neighbouring islands (e.g., Lombok).
Countries occurrence:
Indonesia (Bali)
FAO Marine Fishing Areas:
Indian Ocean – eastern

Population [top]

Population:Very little is known of the population of this recently described species.
Current Population Trend:Unknown
Additional data:
Population severely fragmented:No

Habitat and Ecology [top]

Habitat and Ecology:Biology and habitat unknown; presumably reef-dwelling, inhabiting holes and crevices on reefs, like other related catsharks. The species attains 52 cm total length (TL) with males mature by 43 cm TL (White in review). Presumably oviparous. Diet unknown, but probably dominated by small invertebrates as with many other inshore scyliorhinid species (White et al. 2006).

Threats [top]

Major Threat(s): Caught irregularly by longline (small) and dropline fishers operating over hard substrates off of Jimbaran Bay (Bali). Probably adversely affected by dynamite fishing due to the habitats occupied by this species (White et al. 2006).

Conservation Actions [top]

Conservation Actions: None.
