This siren prefers warm, shallow waters with vegetative cover, such as those in ponds, ditches, and swamps. Nocturnal, it burrows into the silt and debris during the day. It feeds on crawfish, worms, and mollusks. It covers its body with a protective mucus to prevent dehydration during dry periods. It makes a clicking sound when approached or surfacing for air, and squirms when captured.
Breeding takes place in late winter.
Soon after, up to 200 eggs are laid in shallow water. In North America, this siren is found in the lower Rio Grande Valley of Texas and Mexico. In Texas, it is found in the lower Rio Grande Valley.
