Description : Black-spotted Frog, is a small-sized species of frog . This frog is well adapted to live in fast-flowing streams, rocky cascades, and waterfalls in mountainous regions.
It has distinctive coloration. The dorsal surface of its body is brownish-green or olive-green, with distinct black stripes on the back and legs. The ventral surface of the body is whitish-yellow. The skin of this frog species is smooth and moist, which helps them to breathe through their skin. The skin also secretes a slimy mucus that provides protection against predators and parasites.
It is active at night when they come out of their hiding places to feed on insects and other small invertebrates. These frogs have excellent swimming abilities and use their webbed feet to navigate through strong currents. They are also skilled climbers, using their adhesive toe pads to cling to rocks and other surfaces.
Breeding takes place during the rainy season. Males call to attract females to their territory, and females lay their eggs on rocks or vegetation near the water's edge. The tadpoles hatch from the eggs and develop in the water, feeding on algae and other small organisms.
It is not currently considered threatened, habitat loss and degradation due to human activities such as deforestation, mining, and agriculture could pose a significant threat to their survival. This species, like many other amphibians, is also vulnerable to pollution, climate change, and disease outbreaks.
Conservation efforts are needed to ensure the survival of this species and the conservation of its habitat.
