Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2002
Date Assessed: 2002-01-01

Reviewer(s): Lafrance, P., Lourie, S., Marsden, D. & Vincent, A.C.J. (Syngnathid Red List Authority)
Justification:
The species assessed as H. angustus in 1996 is now recognized as H. subelongatus. In assessing the species now identified as H. angustus we found that appropriate data on biology and ecology, habitat, abundance and distribution are not available for this species. Further research is needed.
History:
1996 Vulnerable (Baillie and Groombridge 1996)
1996 Vulnerable
1996 Vulnerable

Habitat and Ecology [top]

Habitat and Ecology: The species has been trawled from depths of 3-63 m (Lourie et al. 1999) and has also been collected from algal reef habitat from 12-25 m depth (Kuiter 2000). This species may be particularly susceptible to decline. All seahorse species have vital parental care, and many species studied to date have high site fidelity (Perante et al. 2002, Vincent et al. in review), highly structured social behaviour (Vincent and Sadler 1995), and relatively sparse distributions (Lourie et al. 1999). The importance of life history parameters in determining response to exploitation has been demonstrated for a number of species (Jennings et al. 1998).
Systems: Marine

Threats [top]

Major Threat(s): This species is known to be caught as by-catch in trawls in northern Australia (S. Lourie, pers. comm.).

Conservation Actions [top]

Conservation Actions: H. angustus was moved under the Australian Wildlife Protection Act in 1998. Further research on this species is needed. It is listed on CITES Appendix II.
