📖 Overview

Specimens were collected by a 2-meter beam trawl or small dredge over (and occasionally in) very soft to firm mud (sometimes with broken shell and plant detritus such as drifts of leaves), at depths of 1-16 m. Water quality varied with the tide, from 25.8-28.4°C and 28.0-30.3 ppt‰ salinity. Reported to co-occur with estuarine fishes such as small polynemids, juvenile sciaenids, engraulids and cynoglossids in this soft-substrate habitat .
