Highighted items on the list are where Hypsoblennius gentilis may be found.
Remarks Found in intertidal shallows (Ref. 11482) but restricted to deeper waters (17-26 m) near Cabo San Lucas. Inhabits bays and nearly estuarine waters. Sympatric with H. jenkinsi and H. gilberti but dominant only in newly developed and transient habitat. Moves to Zostrea beds when their transient habitats are disturbed (Ref. 56052). Territorial (Ref. 37955) particularly the males guarding eggs defending even against the females which spawned it. They exhibit a less developed gular display than H. jenkinsi which is more territorially aggressive. The two species occupy much similar areas and actively competes for space, H. gentilis more often loses to H. jenkinsi. Exhibits odd feeding behavior of hanging vertically in midwater during its feeding period (Ref. 56052). Feeds on small benthic invertebrates and algae (Ref. 37955). Predators of Hypsoblennius include Pralabrax clathartus, Pralabrax maculatofasciatus, Heterostichus rostratus, and Scorpaenichthys marmoratus. Other fishes living in the same area include: Paraclinus integripinnis, Gibbonsia elegans (Ref. 56052).
