Nothing says "biological warfare" quite like a parasitic barnacle that chemically transitions male crabs. Sacculina injects itself into a crab, takes over its reproductive system, and basically says "you're a lady now." The crab starts developing female characteristics and behaviors—all so the parasite can reproduce better. Nature's version of identity theft comes with hormonal changes. Scientists study this while secretly wondering if the barnacles have a tiny evil laugh.
