The male is completely different. Hes very small and looks like a black jellybean with fins. He has no lure, has big eyes, huge nostrils and a fairly small mouth with curved hooked teeth. His body is made of strong red muscle for swimming long distances. Why the difference? Shes looking for food, hes looking for her. She releases anglerfish-type perfumes into the water and he spends all his time swimming around looking and smelling for her. When he eventually finds her (in the dark), he latches on to her side (with his hooked teeth) and drinks her food-rich blood in return for producing the sperm she needs when it comes time to release her eggs.
