Habitat
The Greater siren inhabits slow-moving or stagnant freshwater environments in the southeastern United States, such as swamps, ponds, ditches, and marshes with abundant aquatic vegetation. It prefers warm, shallow waters with muddy substrates and can tolerate low-oxygen conditions. These habitats are often temporary and subject to seasonal drying.
Diet
The Greater siren is carnivorous, feeding on small aquatic prey such as fish, amphibians, crayfish, and insects. It hunts nocturnally by ambushing or scavenging in the water, using its wide mouth to suck in food items. Feeding activity peaks at night in shallow waters.
Behavior
Greater sirens are solitary and primarily nocturnal, spending daylight hours buried in mud or hidden under debris to avoid predators. They exhibit burrowing behavior during dry periods to aestivate and survive in drying habitats. They are not territorial and show minimal social interactions, mainly active in warm water.
Conservation Status
The IUCN status of the Greater siren is Least Concern, with a stable population trend. Major threats include habitat loss from wetland drainage and pollution.
