I wish to understand why some species are found in oceanic rocky reef (like Lutjanus aratus), when many studies support that they need the coastal mangroves to recruit
I have attached a journal article that might provide more insight regarding the reason some species are found in oceanic rocky habitats. In particular, this article provides an Indo-Pacific wide survey of a deepwater snapper, Pristipomoides filamentosus or the Crimson Jobfish. The adults of which are found in rocky habitats at depths of 100-360 m. The article takes into account the correlation between its life history characteristics and its capacity to demonstrate high levels of genetic connectivity across the Indo-Pacific by relating the ability of some P. filamentosus to travel great distances as adults and the long length of its early pelagic phase (60-180 days; which allow new recruits to reach considerable size before settlement) as indicators of the potential this species has to be dispersive, with other factors such as geographic distance, gene flow and diversity (among others) to determine this.
