The Daily Species: Lesser Siren (Siren intermedia)

The Lesser Siren (Siren intermedia) is a slender-bodied aquatic amphibian that spends its days burrowed in silt and debris at the bottom of slow waters. Sirens have a small pair of front legs but lack hind limbs, a loss thought to help them more easily swim through reeds and plants. During drought, they can secrete a protective mucus that cocoons their body to prevent dehydration. Their common name “siren” comes from their ability to be quite vocal, emitting a clicking sound when attacked by a predator.
