metoreissa

Metoreissa is a genus of small to medium-sized, terrestrial salamanders native to the Philippines. The genus was first described by American herpetologist Robert F. Inger in 1960, and it is characterized by its distinctive, elongated body shape, which is adapted for burrowing. Metoreissa species are typically found in forested habitats, where they inhabit burrows and leaf litter.

The genus includes three recognized species: Metoreissa mediatlanticola, Metoreissa platycephala, and Metoreissa rhacophorina. These salamanders are generally small, with snout-to-vent lengths ranging from 3 to 5 centimeters. They have smooth, moist skin and a long, slender tail. Their diet primarily consists of small invertebrates, such as insects and worms.

Metoreissa species are known for their unique reproductive behavior. They are oviparous, meaning they lay eggs, which are typically deposited in moist soil or leaf litter. The eggs are encased in a gelatinous matrix, which helps to protect them from desiccation and predators. The hatchlings are relatively small and independent from birth, requiring little parental care.

Despite their small size and relatively simple biology, Metoreissa salamanders play an important role in their ecosystems. They contribute to nutrient cycling by consuming decaying organic matter and by serving as prey for larger animals. However, they are also threatened by habitat loss and degradation, which has led to their inclusion on the IUCN Red List of Threatened Species. Conservation efforts are underway to protect their habitats and ensure the survival of this unique genus of salamanders.
