Greater Siren vs. Two-toed Amphiuma
The two big eel-like salamanders of the southeastern swamps and ditches; both are often caught on fishing lines. A: Only two small front legs, none at the back in the Greater Siren; four tiny legs, front and hind, each with two toes in the Two-toed Amphiuma. B: Bushy outside gills behind the head in the Greater Siren; no outside gills: only a small slit on each side of the neck in the Two-toed Amphiuma. Amphiumas bite hard; sirens have black dots and yellowish flecks on the sides.
