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.

Famous quotes containing the words life and/or cycle:
“Two such as you with such a master speed
Cannot be parted nor be swept away
From one another once you are agreed
That life is only life forevermore
Together wing to wing and oar to oar.”

“Oh, life is a glorious cycle of song,
A medley of extemporanea;
And love is a thing that can never go wrong;
And I am Marie of Roumania.”
