Ecology

Habitat

Habitat and Ecology

Habitat and Ecology
This species is known from Brazilian offshore islands, where coral-algal reefs are the main coastal habitats, and deep reefs (42 m) at the States of Ceará and Rio Grande do Norte (Sampaio et al. 2006).

It was observed to form groups of up to 30-40 individuals (Lubbock and Edwards 1981). Razorfishes spawn only in pairs (Clark 1983, Thresher 1984, Victor 1987) daily, during a late afternoon spawning period, all year-round (Clark Shen and Scarr pers. obs.)

Justification
This species has a restricted distribution and occurs in relatively low abundances. Although recorded in locations other than the Oceanic islands in the coast of Brazil, it is rare in those locations. However, most of its range of distribution is inside protected areas. It is rarely collected for the aquarium trade and this is not thought to be a threat. This species is listed as Least Concern.

Population

Population
There is no population information available for this species. In Atol das Rocas, it was only observed but not recorded during belt transect census (Rosa and Moura 1995) probably due to its area of occurrence (sand bottom).

Management

Conservation Actions

Conservation Actions
This species distribution overlaps two important protected areas, Fernando de Noronha National Park and Atol das Rocas Biological Reserve. Brazilian national Law (IN 202, 2008) bans collection of oceanic island endemic fish for aquarium trade, so it is protected from harvesting.
