Lion's Mane Jellyfish (Cyanea capillata)

Family: Cyaneid Jellyfish Family (Cyaneidae)

IUCN Conservation Status: Unassessed

Named for its frilly "mane" made up of over 1,200 long, stinging tentacles, the Lion's Mane Jellyfish is among the largest known jellyfish species; while this viral image showing a diver next to a Lion's Mane Jellyfish has been edited to make the jellyfish appear far larger than it actually is, members of this species still dwarf most of their relatives, with a bell ("main body") diameter of over 2.4 meters (7.89 feet) and a tentacle length of as much as 30 meters (98.4 feet), making it one the longest animals on earth. Typically found near the surface in the Arctic, northern Atlantic and northern Pacific Ocean regions, Lion's Mane Jellyfishes, like all jellyfishes, lack brains, eyes, hearts or respiratory organs (instead exchanging gasses directly between the water around them and their extremely thin tissues,) and rely heavily on waves and ocean tides to travel, but are able to slowly propel themselves in a given direction by expanding the 8 bag-like lobes of their bodies to take in water and then forcing it out again to push themselves along (although they can also to some extent detect and react to their orientation and surroundings owing to a series of frilly sensory structures located around their body's rim, know as rhopalia.) Like most jellyfishes the long, trailing tentacles of a Lion's Mane Jellyfish are lined with touch-sensitive, harpoon-like cells called cnidocytes that fire venomous barbs into any animal that touches them, and after a tentacle has stung and ensnared suitable prey (mainly fish, large plankton and smaller jellyfishes) it is pulled back towards the body where the prey is passed through a mouth-like opening on the jellyfish's underside and into a simple body cavity where it is digested, with any indigestible matter, such as shells or bones, later being ejected from the body through the same opening it entered through. The life cycle of the Lion's Mane Jellyfish, like that of most jellyfishes, takes place in 4 distinct stages and seems highly elaborate compared to that of most animals; the bag-like adults that we typically think of as jellyfishes, known as medusas, are either male or female and reproduce sexually by releasing gametes into the water around them, and should these gametes meet they fuse and develop into tiny larvae. The larvae then settle onto a solid surface and develop into polyps (a second, immobile life stage resembling a sea anemone,) and each polyp then asexually reproduces several times, with genetically identical, slow-swimming young splitting off of its body as buds. Each of these asexually-produced individuals will then develop into a medusa, continuing the cycle and meaning that each single instance of sexual reproduction in Lion's Mane Jellyfishes produces multiple asexually-produced offspring. Despite their massive size medusas of this species only live for around a year, although their polyps, which only reproduce under ideal environmental conditions, may remain dormant for longer than this.
