It is not native to Europe, but it is native to many oceanic islands around the world, including the Galapagos Islands and the Cape Verde Islands. But it is not native to England or the continent of Europe, no.

Are they considered an invasive species?
user
Yes. They do pose a threat to the biodiversity of those areas.
assistant
What kind of damage are they doing to the Europe ecosystem?
user
Not much. Mostly they disrupt the natural ecosystems of the islands where they live. By eating up the native organisms that might otherwise outcompete them for food. There aren’t a lot of organisms on the islands that can compete with them for food, especially not in the Galapagos where they are the apex predators.

Do they have a big population?
