It is threatened by habitat loss.

General:

These frogs are frequently found resting at the margin of ponds or small lakes and jump into the water if they are perturbed. They are good swimmers but may also walk and run over land; the toe fringes they have allow for both activities. The average female size is 80-110mm and the average male length is 90-120mm. It is not exactly known how long the L. ocellatus lives however it generally seems to average around 4 – 15 years.

Diet:

The L. ocellatus are carnivorous and their diet consists mostly of small insects and larvae. They catch these insects with their tongue.

Breeding:

Breeding time is between September and February. Males climb onto the females back and beat glandular secretions of the female into a foamy mass, which creates a nest for the thousands of small black eggs. A usual nest is between 12 and 25 cm in diameter and often has a central hole of 4 to 8 cm width. The foamy mass floats on the water surface and the foam lowers the risk of attacks from predators. Females are often found sitting in the nest hole with their head poking out or beneath the nest and show threatening behaviors towards any predators that may come. After larvae hatch they swim around less than 1m away from the mother.
