A "sea devil" lurks off the Japanese coast ... a terror to small fish that meander by. Using a wiggling "lure" atop its head, the yellow goosefish relies on stealth and speed to snatch unsuspecting prey near the seabed. These monsters of the deep come to shallow waters to spawn, oftentimes producing huge transparent floating masses of eggs that in turn attract other predators including the pufferfish. Humans also seek out the goosefish for "anko" hotpot, an umami-rich winter delicacy in Japan.
