How to identify

The Eurycea waterlooensis is a perennibranchiate form which sustains permanent larval morphology. They grow to a total length of 60 – 70 mm. This species lacks external eyes but rather has little subdermal eyespots. It also has 12 coastal grooves. Additionally, it has smaller limbs, in comparison to its closest relations. This salamander has weakly developed tail fins. The ventral section of the tail fin is there just on the posterior half. But the dorsal section is almost gone on the anterior half. This salamander also has a flattened and elongated snout. It also has a glistening and shiny white look due to the reflective connective tissue that lies underneath its transparent skin. Shades of lavender are sometimes exhibited. Lastly, a row of iridophores can occasionally be discovered along the sides of the body and tail.
