Description and life cycle

The Argentine conger is a marine eel with small, fan-shaped pectoral fins. It reaches up to in length. Female specimens gathered from Brazilian waters displayed likely early stages of semelparity, or death after a single instance of reproduction, as the ovaries occupied the specimens' entire abdominal cavities and the bodies had begun to degrade.
