A rare species (Ref. 4264) collected from muddy and sandy bottoms of estuaries and bays. Known to 'walk' over the bottom using its tentacular pelvic fins. Juveniles expatriate to tropical regions; adults mainly found in muddy estuaries where they pair. Sometimes they are seen partly buried but also feed during the day. Sometimes found floating on the surface (Ref. 48635). Sometimes occurs in seagrass areas (Ref 90102). Feeds on small benthic organisms (Ref. 68964).
一个稀有的种 (参考文献 4264) 采集自河口与海湾的泥泞多沙的底部了。 已知了 '步行' 在底部之上使用它的触丝腹鳍。 稚鱼游离栖地到热带区域; 成鱼主要发现于泥泞的河口了它们在哪里配对。 有时他们部分被见到埋藏也在白天觅食。 有时发现漂浮在表面上.(参考文献 48635)
