Fact File

Distribution: Greater Sirens occur primarily in the Coastal Plain of Virginia. They use a wide range of freshwater aquatic habitats as long as there is abundant vegetation.

Identifying Characteristics

Did You Know?

In 2018, a new species of siren from northern Florida and southern Alabama was formerly described: Reticulated Siren (Siren reticulata).

Role in the Web of Life

Sirens are fully aquatic and active at night; they hide in vegetation during the day. When wetlands dry, sirens form a cocoon from skin secretions and aestivate until water returns. Females lay 100–500 eggs singly or in small clusters adhered to leaf litter in late-winter and early spring. They eat a wide range of invertebrates and even algae.
