they are 5 to 7 mm in length, but highly vascular and filled with air. They are very sensitive to desiccation and warm temperatures. More than 83 °F (28 °C) can be fatal, and they can only tolerate a water loss of 19.4 percent of initial body weight at most (compared to 29.0 to 32.9 percent

Courtship is terrestrial. The male will deposit a spermatophore on the ground, which is then picked up by the female. The eggs have a pale yellow-white ova, and are deposited separately and haphazardly in slow-flowing water. Sometimes communal oviposition occurs. They are attached neither to each

Maximum adult snout-vent length is 6 cm. They have complete metamorphosis, but a few neotenic traits have been found, like the presence of conical teeth and reduced or absent nasal bones. Nasal bones have never been seen in
