Physical characteristics: Freshwater sponges are crustlike, branched, or clumped. The texture is fragile and soft, and the color is whitish or green. Freshwater sponges have irregularly scattered and barely visible water-exit holes.
Geographic range: Freshwater sponges live in North America, Europe, and Asia.
Habitat: Freshwater sponges live in standing and running fresh water.
Diet: Freshwater sponges are filter feeders.

Freshwater sponges reproduce sexually during the summer, giving birth to live larvae.
