This species is known for its distinctive, sad-looking expression, which has earned it its common name. The Black Rain Frog has dark, mottled brown skin that helps it blend into its natural habitat, making it difficult for predators to spot. It is a small species, reaching a maximum length of about 4.5cm. Despite its small size, it is a robust amphibian well adapted to life in its native habitat.
Humans do not commonly see the Black Rain Frog as it is primarily a nocturnal species. During the day, it burrows underground to avoid the hot South African sun and only emerges to hunt for food at night. Its diet consists of various insects, spiders, and other small invertebrates. This species is also known for its unique vocalizations, which attract mates and deter predators. The calls of the Black Rain Frog have been described as sounding like a soft, monotonous raindrop-like plop, giving it its common name. Despite its unusual appearance and interesting behavior, the Black Rain Frog remains a relatively unknown species, and much about its life and behavior remains to be discovered.
The Black Rain Frog is known for its unique behavior when it feels disturbed or threatened. When this occurs, the frog will puff up and enlarge its body, adopting a more aggressive posture. This defensive reaction allows the frog to protect itself from potential danger.
However, the Black Rain Frog displays a different behavior during mating season. The female frog will secrete a sticky substance on its back to keep the male from falling off during mating. This behavior is known as “adhesive amplexus.” The female frog will not let go of its partner during this time, showing that the Black Rain Frog is not necessarily averse to company. Instead, it is just adapting to different situations and behaviors to ensure its survival and success.
