How the venomous lionfish invaded the Atlantic Ocean: here.
Researchers have little information about how grown lionfish might invade or move to new waters because tracking small marine organisms poses difficulties. One way to investigate their movements, though, is to study stable isotopes in their ear-bones: here.
An invasive species first identified in the Mediterranean Sea just eight years ago is likely to become a permanent feature of the region, a new study suggests. First seen off the coast of Cyprus in 2012, lionfish (Pterois miles) are now thriving and well-established in the area and across southern Europe: here.
