Ephebopus murinus, commonly known as the Skeleton Tarantula, is native to the tropical rainforests of northern South America. This species is known for its distinctive skeletal-like markings on its legs. It exhibits burrowing behavior, constructing deep burrows to reside in. Unlike many tarantulas, it possesses urticating hairs on its pedipalps, used for defense.

Ephebopus murinus, commonly known as the Skeleton Tarantula or Skeleton Leg Tarantula, is native to the tropical rainforests of northern South America. Its primary geographical distribution includes parts of Brazil, French Guiana, Guyana, and Suriname.

The species resides in humid and dense rainforest ecosystems characterized by high humidity levels, consistent temperatures ranging from 24°C to 28°C (75°F to 82°F), and abundant rainfall throughout the year. These conditions support a rich biodiversity and dense vegetation.

Ephebopus murinus typically inhabits the forest floor, where it constructs burrows in the soft, moist soil. It is a fossorial species, meaning it digs and lives in burrows underground. This behavior provides protection from predators and harsh environmental conditions. The tarantula's niche involves preying on small invertebrates, contributing to the ecosystem's balance by controlling insect populations.
