Almost immediately, however, the pair discovered something that was wholly unexpected: a mushroom body—a key neural structure most famously associated with visual and olfactory learning and memory in insects. “It was a huge surprise,” says Wolff, noting that the two lineages are separated by hundreds of millions of years of evolution. “We were really excited because we’d never seen a mushroom body so much like an insect’s mushroom body anywhere outside of insects, especially not in crustaceans.”
