Anglerfish of the family Ceratiidae are sexually dimorphic. Females are the sex that most people would recognize as deep sea fish, with their glowing lures at the ends of long fishing rods extending from the forehead. Many species also have long teeth and a bulbous body. Males are small fish (usually about 2.5cm or smaller). Males don't have the big teeth or the glowing lures. They have a well developed sense of smell and they spend the first part of their lives searching for a female of their own species. If they find one, they swim up, bite her, and hold on. In fact, the male holds on so long that the skin of the female grows over the front of his face and he ultimately becomes connected to her circulatory system. At that point he is fused to her body and entirely reliant on her for food. When the time comes for reproduction, he provides sperm to her through the circulatory system. Females can sometimes be found with more than one male attached. | |
