Active at night (nocturnal).
Courtship involves male pursuing female, positioning himself so anterior portion facing female’s anterior region. While in front of female, he fans/slaps tail dispersing mating pheromones. After fanning completed, he walks in front of female. As he walks away, spermatophore (gelatinous sperm packet) deposited. He walks in front of spermatophore, positioning himself perpendicular to female. Female follow/chases male w/ snout touching male’s tail. Afterwards, female picks up male’s spermatophore in her cloaca.
After mating, females deposit 45-60 eggs.
After 9 days, eggs hatch as aquatic tadpoles staying in this stage for 3-4 months, maturing faster in warmer water. As they metamorphose, they lose gills & tail changes losing swimming membrane & parotid glands near head become noticeable. This is when eft stage entered, becoming terrestrial juveniles. They stay in this stage until 20 months-2 years old.
While increasing & now downlisted from critically endangered to threatened, it’s still at high risk due to water pollution, restricted range, pet trade, habitat loss, stream damming, drought, & predation of eggs/larvae by barbel fish.

Fun Fact(s):
