Surai singa: Perbedaan antara revisi

Sementara Ubur-ubur Surai Singa umumnya menggunakan tentakel mereka untuk menangkap mangsa, [[anemon laut]] dapat menangkap tentakel mereka, yang kemudian menjadi kusut, terkoyak dan dikonsumsi.https://en.wikipedia.org/wiki/Lion's_mane_jellyfish#cite_note-3<br />

 

Although capable of attaining a bell diameter of over {{convert|2|m|ftin}}, these jellyfish can vary greatly in size; those found in lower latitudes are much smaller than their far northern counterparts with bell about {{convert|50|cm|in}} in diameter. The [[tentacle]]s of larger specimens may trail as long as {{convert|30|m|ft|abbr=on|sigfig=1}} or more. These extremely sticky tentacles are grouped into eight clusters, each cluster containing over 100 tentacles,<ref>{{cite web|url=http://www.scubatravel.co.uk/lionsmane2.html |title=Lion's Mane Jellyfish |publisher=Scubatravel.co.uk |date= |accessdate=2010-09-03}}</ref> arranged in a series of rows.

 

 

== Behavior and reproduction ==

Lion's mane jellyfish remain mostly very near the surface at no more than 20&nbsp;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 (biology)|medusa]] stage and [[asexual reproduction]] in the [[polyp]] stage.<ref name="typesofjellyfish1"/> 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.<ref name="typesofjellyfish1"/> 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 [[polyp]]s. The polyps begin to reproduce asexually, creating stacks of small creatures called ephyraes.<ref>{{cite web|url=http://www.dnr.sc.gov/marine/pub/seascience/jellyfi.html |title=SCDNR - Jelly fish |publisher=Dnr.sc.gov |date= |accessdate=2010-09-03}}</ref> The individual ephyraes break off the stacks, where they eventually grow into the medusa stage and become full grown jellyfish.<ref>{{cite web|url=http://www.teara.govt.nz/en/open-ocean/2/2 |title=Open ocean - Jellyfish life cycle - Te Ara Encyclopedia of New Zealand |publisher=Teara.govt.nz |date=2009-03-02 |accessdate=2010-09-03}}</ref>

On July 21, 2010, around 150 people are thought to have been stung by the remains of a lion's mane jellyfish that had broken up into countless pieces in [[Rye, New Hampshire|Rye]], [[New Hampshire]], in the United States. Considering the size of the species, it is possible that this mass incident was caused by a single specimen.<ref>{{cite web |url=http://www.wmur.com/news/24341753/detail.html |title=150 Stung By Jellyfish At Rye Beach - New Hampshire News Story - WMUR Manchester |publisher=Wmur.com |date=2010-07-21 |accessdate=2010-09-03}}</ref>

 

The lion's mane jellyfish appears in the [[Sherlock Holmes]] short story "[[The Adventure of the Lion's Mane]]" published in ''[[The Case-Book of Sherlock Holmes]]''. Holmes discovers at the end of the story that the true killer of a school professor who died shortly after going swimming (shouting "the lion's mane" before he succumbed) was actually this jellyfish. Suspicion was originally laid upon the professor's rival in love, until the latter was similarly attacked (he survived, although badly stung). In the context of the story, it is only because the school professor has a weak heart that he succumbs, as is confirmed by the survival of the second victim.

 

On the popular television program ''[[QI#Mistakes and corrections|QI]]'' the show claimed that the longest animal in the world was the lion's mane jellyfish, but this was later corrected - as the longest in the world is actually the [[Lineus longissimus|bootlace worm]].
