Inhabit seagrass and marine algae areas of estuaries and seaward reefs; also on steep mud slopes. Found in open water and attached to drifting Sargassum up to 20 km from shore. Adults in pairs (Ref. 48635). Benthic to pelagic (Ref. 58302). Feeds on zooplankton (Ref. 85309). Ovoviviparous (Ref. 205).
