The sea nettle is a marine jellyfish that feeds mainly on zooplankton and ctenophores, and other jellyfish. Its mouth is in the center of the body on the bottom end and this oral cavity opens to the gastrovascular cavity. Its mouth is surrounded by tentacles that help capture food. Each tentacle has thousands of nematocysts; on humans this causes a rash. The sea nettle reproduces both asexually and sexually.
