Declining

Overview

Coniophanes andresensis, the San Andres snake, is a species of snake in the family Colubridae. The species is native to San Andrés of Colombia.

Coniophanes andresensis faces severe threats from habitat destruction due to agricultural expansion and urban development on Isla San Andrés. The species' extremely limited range makes it particularly vulnerable to any environmental changes or human activities on the small Caribbean island. Introduced species and potential climate change impacts on the island's ecosystems pose additional risks to this endemic snake's survival.
