Lionfish Pterois volitans and P. miles. Native range: Indo-Pacific and Red Sea. Invasive range: East Coast of the United States and Caribbean Sea. Impacts: Lionfish can reduce the abundance of small native fish by up to 95% on some coral reefs. Reducing lionfish numbers and restoring populations of native fish can be challenging, given the lionfish’s ability to inhabit diverse habitats. High recruitment pressure from lionfish can create permanent alterations to native reef fish communities.
