Mantidactylus tornieri is a species of frog in the family Mantellidae, endemic to Madagascar. It was first described by George Albert Boulenger in 1882.
Taxonomy
- Kingdom: Animalia
- Phylum: Chordata
- Class: Amphibia
- Order: Anura
- Family: Mantellidae
- Genus: Mantidactylus
- Species: Mantidactylus tornieri
Distribution and Habitat
Mantidactylus tornieri is known only from Madagascar, where it inhabits humid forest environments, particularly along streams and in the leaf litter of lowland and montane rainforests. Records indicate its presence across the eastern side of the island, at elevations ranging from sea level to approximately 1,200 m above sea level.
Physical Description
The species is a small to medium-sized frog. Dorsal coloration is generally brown or gray, often with darker mottling, while the ventral surface is lighter. Detailed morphological characteristics, such as toe webbing and skin texture, correspond to typical traits of the genus Mantidactylus.
Ecology and Behavior
Mantidactylus tornieri is primarily a nocturnal, terrestrial species that breeds in or near small freshwater bodies. Males call from concealed positions within leaf litter or near the water's edge during the breeding season. The reproductive mode is oviparous, with eggs deposited in water; tadpoles develop in aquatic environments before metamorphosing into terrestrial juveniles.
Conservation Status
The International Union for Conservation of Nature (IUCN) lists Mantidactylus tornieri as Least Concern. This assessment reflects its relatively wide distribution, presumed large population, and tolerance of some habitat modification. Nonetheless, ongoing deforestation and habitat degradation in Madagascar could pose future threats.
