Cuban boa description

The Cuban boa (Epicrates angulifer) is the largest species in its genus ⁽⁴⁾, and the largest snake in the West Indies (excluding Trinidad) ⁽³⁾.

An attractive snake, the Cuban boa varies in appearance across its range. In western Cuba, it tends to have bold, dark brown or black markings on the top and sides of the body, whereas further east, it tends to be paler with less distinguished markings ⁽³⁾.

Also known as

Cuban tree boa.

French

Boa De Cuba.

Spanish

Maja De Sta. María.

Size

Length: 2.0 - 4.8 m ⁽³⁾

Cuban boa biology

The Cuban boa is largely nocturnal ⁽⁶⁾, and its diet consists of birds, rodents, bats and lizards (Cyclura species) ⁽³⁾. It has been known to prey on small snakes, such as the woodsnake (Tropidophis melanurus). The juvenile tends to feed on small lizards in the Anolis genus that are found in trees. The Cuban boa is easily agitated and will habitually strike ⁽³⁾.

It is a skilful predator and prey, such as rodents, are ambushed on the ground. Remarkably, it is also able to snatch bats from the air, as they enter or exit roosting caves ^{(3) (5) (6)}. Heat-sensing pits in crevices on the mouth detect temperature changes as low as 0.10 degrees Celsius, enabling the Cuban boa to detect warm-blooded prey in the dark ⁽⁶⁾. Prey is initially seized by the Cuban boa with its teeth, and it then coils its body around the prey and squeezes, eventually causing suffocation of the prey ⁽⁷⁾.

Like other boas, the Cuban boa gives birth to live young, as opposed to laying eggs ^{(6) (7)}. The embryos remain in a soft membrane within the female, and the gestation period is approximately four months ⁽⁷⁾. Shortly before birth, the young break out of the membrane and the female Cuban boa then gives birth to between one and seven offspring ⁽³⁾. The young measure approximately 40 centimetres in length, and are independent of any parental care from birth ⁽⁷⁾.

Cuban boa range

The Cuban boa is endemic to Cuba, and is distributed throughout the island. It can also be found on Isla de la Juventud, a Cuban island off the southwest coast of Cuba ⁽³⁾.

Cuban boa habitat

The young Cuban boa is mainly arboreal, inhabiting trees in tropical forests. It becomes more terrestrial as it grows ⁽⁴⁾ and can be found in moist and dry woodland as well as rocky habitats ⁽³⁾. The Cuban boa has also been observed coiled around roots at the entrances to caves ⁽⁵⁾.

Cuban boa status

The Cuban boa is classified as Near Threatened (NT) on the IUCN Red List ⁽¹⁾ and listed on Appendix II of CITES ⁽²⁾.

Cuban boa threats

The Cuban boa is persecuted by local villagers, who believe the snake targets chickens and other poultry ⁽⁷⁾.

Since it lives on small islands, natural disasters such as forest fires or cyclones may potentially wipe out the Cuban boa population ⁽⁷⁾.

Cuban boa conservation

International trade in the Cuban boa is restricted by its listing on Appendix II of the Convention on International Trade in Endangered Species (CITES) ⁽²⁾. The Cuban boa is also included on the European Endangered species Programme (EEP), a breeding programme coordinated by Prague Zoo. Bristol Zoo Gardens has successfully bred the Cuban boa for 20 years ⁽⁷⁾.
