Life Cycle
Adult lampreys spawn in rivers and then die. The young larvae, also called "ammocoetes", spend several years in the rivers, where they live burrowed in fine sediment, filter feeding on detritus and microorganisms. Then, ammocoetes undergo a metamorphosis that lasts several months. Some species do not feed after metamorphosis, while others migrate to the sea or lakes, where they feed on different species of fish and even on marine mammals. Species whose adults migrate to the sea begin preying on other fish soon after metamorphosis, even as they begin swimming downstream.
