Did You Know?
Sirens sometimes make a clicking noise, but the function is unknown.
Role in the Web of Life
Root masses of aquatic plants provide cover. When the water dries out, sirens will aestivate by forming a cocoon in the substrate with secretions from skin glands where it will wait until it rains. Females lay 200–500 gelatinous eggs in winter amongst dense vegetation. Food consists of worms, insect larvae, and small fish.
