Ecology Summary - Eucinostomus gula

Language:

Main Ref.	Vega-Cendejas, M.E., M. Hernandez and F. Arreguin-Sanchez, 1994
Remarks	Inhabits shallow waters, being especially abundant over mud bottoms in mangrove-lined lagoons or creeks; larger individuals may also occur on vegetated sand grounds in marine areas. Enters fresh water in limestone regions (Ref. 7251). May occur in aggregations (Ref. 3722). Probably feeds on small benthic invertebrates (Ref. 3722). Foraged over the bottom by swimming at about 3-4 cm above the bottom and stopped at a selected site. It tilts its body by about 45° and protrude its mouth and buried it into the sand. Sediment are ejected through its mouth and gill openings producing a scattered sandy cloud of thin sediment (Ref. 40104). See Ref. 42268.
