Although seagrasses are rare along the Pacific coast of Central America, large meadows can be found in Golfo Dulce. An area of Halophila baillonii was recently reported (Samper-Villarreal et al. 2014). In the upper reaches of the inlet, a large bed of seagrass consisting of H. baillonis and a filamentous species, possibly Halodule beaudettei, supports hundreds of Pacific green sea turtles (Bessesen & Saborío-R 2012; see SEA TURTLES). Mangroves (Samper-Villarreal & Silva-Benavides 2015) provide critical habitat for many species in Golfo Dulce (Feutry et al. 2010; see FISHES).
