Freshwater Sponges (Porifera: Spongillidae) of the Wild and Scenic Red River, Kentucky

Abstract

Freshwater sponges are common inhabitants of rivers, streams, and lakes, but little information exists for the freshwater sponges of Kentucky. During 26 and 27 July 2016, a survey was conducted in the recreational section of the wild and scenic Red River. Thirty-three sponge specimens were collected at five sites from which Radiospongilla crateriformis, Spongilla lacustris, and Trochospongilla horrida were identified. Due to its hydrographic diversity and the considerable diversity of other aquatic fauna, we expect future surveys will reveal Kentucky rivers and streams to support a rich and diversified sponge fauna.
