Comprehensive DescriptionRead full entry
Pseudoeurycea aquatica is moderately large sized (68.4-70.5mm) and its features are specialized for aquatic life. The head is broad and triangular-shaped. The snout is bluntly pointed (with a 70mm posterior vent) and the eyes are small. Remarkably, the nostrils are external but closed due to flap-like structures. The adductor and depressor muscles of the jaw are slightly enlarged and very strong. The mouth holds few but large maxillary teeth. The tail is long, slender, and marked by a constriction at its base. Similarly, the limbs are very long. There are four unwebbed and well-formed digits, plus a prominent but short fifth toe (Wake and Campbell 2001).
Dorsal coloring is reddish brown with distinct mottling that is heavily dark brown. Upper eyelids are lighter in color and sparsely spotted. Slight color intensity variations exist. Females are darkly colored compared to males (Wake and Campbell 2001).
Among the Bolitoglossini, Pseudoeurycea aquatica is the only aquatic species. It shares similar morphology with Pseudoeurycea smithi (Wake and Campbell 2001).
