Biology

C. godmani sensu lato has a wide range, but has now been split into new species in the southern part of its former range (C. sasai and C. wilsoni).

Varying head scales, some of them enlarged. Appearance similar to small montane rattlesnakes, but lacking the rattle. Also similar to Bothrops spp. in appearance, but on average smaller (<1 m). C. tzotzilorum barely reaches 50 cm. Basic colouring in shades of brown, grey and yellow. Smaller to large, dark, triangular or trapezoidal blotches both sides of the spine.

Habitat: lower montane wet forest, cloud forest, lower montane dry forest and high montane forest and meadows, 1,400–3,491 m (C. godmani); pine-oak forest, 2,100–2,300 m (C. petlalcalensis); humid pine-oak forest, 2,050–2,500 m (C. tzotzilorum).

Risk

Only a few cases reported, none of them fatal. Venom of C. godmani might have a haemotoxic, locally cytotoxic and myotoxic action (Campell and Lamar 2004).
