زيست شناسي     واژه نامه (بعنوان مثال epibenthic)

Generally present in coastal marine water (Ref. 37039). Enter brackish- and freshwaters, but perhaps not always or not consistently anadromous (Ref. 188), although strongly migratory within rivers (Ref. 10294) , mostly in fast-flowing water where they are renowned for leaping. Feed on small fishes, the juveniles on insects. Spawning times and places not certain. Adults serve as hosts to the larvae (glochidia) of the economically valuable pearly mussel (Fusconaia ebena) of the Mississippi basin (Ref. 188).
