Siren intermedia


The only species of its genus in MS, this eel-like salamander can be found throughout Mississippi in various bodies of water. They are dark brown or gray with dark spotting patterns. They are highly aquatic and elongated like amphiumas, but have a set of external gills and do not grow as large. Adults range from 7 – 27 inches (Powell et al., 2016). Legs are more developed. Only one subspecies is encountered in MS.
