In Fairbanks, Alaska residents are venturing outside with caution as live lampreys are falling from the sky according to the Alaska Department of Fish and Game.
Lampreys are a parasitic species of fish with a funnel of teeth for a mouth. They attach to their host and suck its blood.
Lampreys spawn in the Chena River which runs through Fairbanks.
It is theorized that sea gulls have been catching them in the river and are accidentally dropping them on land.
