The smooth softshell turtle (Apalone mutica) is a softshell turtle of the family Trionychidae. It is endemic to North America.

Geographic range

It lives mainly in the Mississippi River drainage, including the Ohio River and the lower Allegheny River.

Description

The smooth softshell turtle is usually brown or olive-colored, often with darker dots or dashes. It is the only softshell without ridges in the nostrils. Females are 18-35.6 cm (7-14 inches); males, 12.5-17.8 cm (5-7 inches).

Diet

Typical foods include various macroinvertebrates such as aquatic insects, crayfish, and occasionally a fish. [4]

Reproduction

From May to July, the females lay bunches of three to 28 eggs about 100 m from water in sandy areas.[5]

Sympatric species

Apalone mutica is sympatric with the spiny softshell turtle (Apalone spinifera) over much of its range.[6]
