Lucernariidae [Lucernariidae]

Description

Lucernariidae is a family of stalked jellyfish characterized by their bell-shaped bodies supported on a stalk, which anchors them to seagrasses, algae, or other submerged objects. These jellyfish have a distinctive appearance, with four to eight arms radiating from the central body, each arm equipped with tentacles that are laden with stinging cells used for capturing prey. The members of this family are typically found in cooler, temperate waters and are known for their ability to contract their bodies and close their tentacles to protect themselves. Lucernariidae species play a role in marine ecosystems as predators of small marine organisms.
