Arctic, northern European, North American Atlantic and Pacific, southern Australian, and waters (Lion's mane jellyfish- Cyanea capillata).
This type of jellyfish is a coldwater species, it cannot cope in warm water (Lion's mane jellyfish). The medusae prefer cool temperatures below 70 degrees.
"They possess a benthic polyp stage (larva) which reproduces asexually to give rise to ephyrae; these grow into dioecious, planktonic medusae (adults) that produce planulae (motile stereogastrulae), and the latter settle to the benthos to form polyps, completing the cycle "(Brewer).
Cyanea capillata can sexually reproduce during the medusa stage and can asexually reproduce during the polyp stage (Lion's mane jellyfish).
Feeds on zooplankton, small fish, ctenophores, and moon jellies (Lion's mane jellyfish). Their long tentacles capture large prey and bring them into their oral arms, where they are then enveloped and digested (Lion's mane jellyfish- Cyanea capillata).
