A removal project aims to reduce numbers of the unwelcome arrival that has quickly become prevalent
Non-native lionfish have become increasingly common in parts of the Mediterranean in recent years, threatening local ecosystems and posing a hazard to humans through their venomous spines.
Marine biologist Prof Jason Hall-Spencer first saw a lionfish off the coast of Cyprus in 2016. It was just an individual, but the species – which produce about 2 million eggs each year and lack natural predators in their new environment – have quickly become prevalent. “In some places, I’ve seen 40 on one dive,” said Hall-Spencer, from the University of Plymouth.
