Like the Cayman Racer, the Cayman Ground Boa is completely harmless; however, it too is often mistaken for a dangerous snake. Cayman Ground Boas are variable in body colour, from pale (pictured above) through to light or very dark brown., Juveniles show a bold black and white patterning along the back, which gradually changes to the adult colour as they mature. This is a nocturnal snake often found around rotting wood and in other natural ground debris. This snake is well known for its initial release of a vile odour when stressed by handling., This species is endemic to the Cayman Islands, where it occurs on the western half of Grand Cayman (Seidel and Franz 1994, Echternacht et al. 2011). Elevation ranges from 3 to 18 m asl. Total adult population size and trend is unknown., Tropidophis caymanensis, or the Cayman Islands dwarf boa, is a species of snake in the Tropidophiidae family. It is endemic to the Cayman Islands. (Source: Wikipedia, 'Tropidophis caymanensis', https://en.wikipedia.org/wiki/Tropidophis_caymanensis, CC BY-SA 3.0 .

Despite being related to the giant boa constrictor of South America, Cayman Dwarf boas scarcely grow longer than a ruler and are harmless to people and pets., The Cayman Islands Dwarf Boa, scientifically known as Tropidophis caymanensis, is a small snake species found exclusively on the islands of Grand Cayman, Little Cayman, and Cayman Brac in the Caribbean Sea..
