Habitat and Ecology [top]

Habitat and Ecology:This demersal species is usually found among vegetation in bays and estuaries, and occasionally among floating Sargassum species (Dawson 1985).  Little is known about its feeding habits, but it likely consumes small benthic and/or planktonic crustaceans such as mysids, harpacticoid copepods, and gammarid shrimp like other pipefishes do (Kendrick and Hyndes 2005, Garcia et al. 2005). They are ovoviviparous, and the males brood embryos beneath their tail prior to giving live birth (Breder and Rosen 1966, Dawson 1985).
Continuing decline in area, extent and/or quality of habitat:Unknown
Movement patterns:Unknown

Use and Trade [top]

Use and Trade: This species was not present in the dried trade from 1998-2001 (Vincent et al. 2011a). It may be used in the aquarium trade as other pipefishes often are Vincent et al. 2011b), but this has not been observed and levels of offtake are unknown.

Threats [top]

Major Threat(s): There are no major threats known for this species. However, since it is found in estuaries, coastal development and pollution may be a local threat to this species in some areas of its range.

Conservation Actions [top]

Conservation Actions: There are no known conservation measures for this species. However, its distribution falls into a number of Marine Protected Areas in the Eastern Tropical Pacific region (WDPA 2006).
