SCUBAMART Mangga Dua Indonesia

The worlds largest known jellyfish can reach a diameter of 2.5 m / 8ft and its tentacles can grow to be half the length of a football field.

The lion's mane jellyfish (Cyanea capillata), also known as hair jelly, is the largest known species of jellyfish. Its range is confined to cold, boreal waters of the Arctic, northern Atlantic, and northern Pacific Oceans.

Similar jellyfish, which may be the same species, are known to inhabit seas near Australia and New Zealand. The largest recorded specimen found, while the lion's mane jellyfish generally use their stinging tentacles to prey, sea anemones can capture their tentacles, which then become tangled, torn apart and consumed

Lion's mane jellyfish remain mostly very near the surface at no more than 20 m depth, their slow pulsations weakly driving them forwards, they depend on ocean currents whereby they travel great distances.

The jellyfish are most often spotted during the late summer and autumn, when they have grown to a large size and the currents begin to sweep them closer to shore.
Like other jellyfish, Lions manes are capable of both sexual reproduction in the medusa stage and asexual reproduction in the polyp stage.

Lion's mane jellyfish have four different stages in their year-long life span: a larval stage, a polyp stage, an ephyrae stage, and the medusa stage. The female jellyfish carries its fertilized eggs in its tentacle where the eggs grow into larva. When the larva are old enough, the female deposits them on a hard surface where the larva soon grow into polyps.

The polyps begin to reproduce asexually, creating stacks of small creatures called ephyraes. The individual ephyraes break off the stacks, where they eventually grow into the medusa stage and become full grown jellyfish.

Most encounters cause temporary pain and localized redness. Lifeguards in Australia wear pantyhose as a simple protection against jellyfish stings. In normal circumstances, and in healthy individuals, their stings are not known to be fatal. Common remedies include: vinegar, isopropyl alcohol, and meat tenderizer.
