Comments: Occurs in shallow creeks with sandy-muddy substrate rich in plant debris.  Rarely found in principal river beds (Ref. 27188).  Although not abundant, it appears to be well-adapted to its environment as evidenced by its leopard outfit which enables it to camouflage itself.  The isolated captures suggest a solitary existence.  Unlike the <i>Tatia</i> which lives mostly in estuaries, <i>G. leopardum</i> appears to live mainly in the upstream portion of rivers (Ref. 35381).
