Eastern Sand Darter
Ammocrypta pellucida (Agassiz, 1863)
Ray-finned Fishes

Habitat [-]
Eastern sand darters mainly inhabit lakeshores up to 20 m deep and shallow moderately-sized streams less than 50 cm deep with a clean sandy substrate composed of medium-size sand particles, very little vegetation, and a current fast enough to prevent siltation but slow enough so that sand is not disturbed, about 0-20 cm/sec (Spreitzer 1979; Smith 1985; Daniels 1993). During a habitat study conducted in 1984 by Daniels (1993), a majority of eastern sand darters were captured along the depositional side a short distance downstream of a riverbend.

Associated Ecological Communities [-]
  • Deepwater river
    The aquatic community of very large, very deep, quiet, base level sections of streams with a very low gradient. In places the water is deep enough so that light cannot reach the river bottom.

Associated Species [-]
  • Johnny Darter (Etheostoma nigrum)
  • Tessellated Darter (Etheostoma olmstedi)
