Lionfish

Invasive lionfish have established a dense population on U-352, sheltering inside the wreck's compartments and along the hull ledges. Their venomous spines make them effectively predator-free in Atlantic waters, and they reproduce rapidly, posing a significant threat to juvenile reef fish populations. Research teams from NOAA regularly survey this wreck to monitor the lionfish invasion's impact on the broader wreck ecosystem.
