How do jellyfish lurk?

jellyfish lurk water

yea

The jellyfish eats dead or living small fish, eggs, zooplankton, and other underwater invertebrates that get caught in their tentacles as they drift to the current. cool

jellyfish don't hunt they just float around in the ocean and i think they have some kind of sensors to find them and kill them with there stinging and sometimes posonous tentacles
