Dominica Boa

Boa nebulosa

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

The Dominica boa is a boa endemic to that Caribbean island, separated as a species of its own from the mainland boa constrictor in 2016. It is the largest snake on Dominica and a key predator of introduced rodents. Hurricane Maria, which devastated the island in 2017, seriously affected its habitat and its only known population.

Fun facts

  • It was recognised as a species of its own in 2016, when it was split from the mainland boa constrictor along with the Saint Lucia boa: until then they were regarded as island populations of a single widespread species.
  • Hurricane Maria in 2017 destroyed much of Dominica's forest and seriously affected the species' only population, whose subsequent monitoring is still under way.
  • It is the island's largest land predator and controls the introduced rat populations, though direct persecution by local people remains a problem.
