Description

Mantella Haraldmeyer was first discovered and described in 1981. The skin is smooth. The middle ear is distinctly expressed. The back is brown, with a dark "V" -shaped or triangular spot in the hind legs. The upper half of the iris is slightly pigmented. You can tell the sex of the mantell by the pale horseshoe-shaped pattern on the frog's throat. In males, the pattern extends to the back of the throat; in females, there is a white stripe instead of a horseshoe pattern.

Reproduction

Reproduction does not take place in water (eggs are not laid in water). After mating, the female looks for a suitable nesting place (it should be wet). This can be moss, sponge, crevices in logs, the back of stones or bark. One female mantella lays up to 65 yellowish eggs (2.2 mm in diameter). The rains wash the eggs out of the nests and transfer them to shallow stagnant bodies of water or puddles.

Season / period of breeding

Reproduction begins with the onset of the rainy season (November-March).

Courtship ritual

Courtship takes place secretly, under bark or logs.

Development

Tadpoles are herbivores - they feed on algae and detritus. Up to 10-11 mm in size. After metamorphosis, the mantella begin to hunt insects (small aphids). The color of adolescents is the same as that of adults.

Population / conservation status

Mantella Haraldmeyer is an endangered species.
