A slow slaughter beneath the waves is surprisingly social: one species of sea slug attacks its anemone prey in teams. The finding highlights how predatory collaboration isn’t limited to more complex carnivores like wolves and lions.
“[The study is] a nice demonstration that the same forms of cooperative behaviour have evolved as a way of solving the challenges of life in vastly different organisms and ecological circumstances,” says Michael Cant at the University of Exeter, UK, who wasn’t involved with the research.
