Image from this article to appear as POTD soon
Hello! This is a note to let the editors of this article know that File:Cross section Olindias formosa en.svg will be appearing as picture of the day on 2018-10-24. You can view and edit the POTD blurb at Template:POTD/2018-10-24. If this article needs any attention or maintenance, it would be preferable if that could be done before its appearance on the Main Page. Thanks &mdash; Amakuru (talk) 22:52, 21 October 2018 (UTC)

sentence tweak
I think I see what you are getting at, please help me to rewrite the sentence.


 * The box jellyfish is largely similar in structure. It has a squarish, box-like bell from each of the four lower corners of which hangs a short pedalium or stalk which bears one or more long, slender tentacles. The rim of …

Maybe some recasting of the sentences, break them down in some way to clarify the unfamiliar structure? cygnis insignis 11:28, 5 January 2019 (UTC)


 * Done, I've split it up to simplify it - the fewer each-of-whichs with grammar too difficult for some large fraction of readers the better. (Feel free to parse that with an old-fashioned grammar primer.) All the best, Chiswick Chap (talk) 12:46, 5 January 2019 (UTC)


 * That was fast! Here's what I came up with:


 * The box jellyfish is largely similar in structure, with one or more long, slender tentacles borne by a short pedalium, or stalk, hanging from each of the four corners of its squarish, box-like bell.


 * This grammar seems to be appropriate. Thoughts? Tgroch (talk) 13:01, 5 January 2019 (UTC)


 * Perhaps, but the new structure with split sentences is simpler. Chiswick Chap (talk) 13:31, 5 January 2019 (UTC)


 * , I prefer your casting of the sentence. Note there is a licensed use of the term box jellyfish as both singular and plural (ie. fish), the singular 'is' bothers me and 'are' would avoid the idea it is similar to some other unnamed thing. Or reorder to "The structure of box bellyfish is similar"? A nice little diversion, cheers, it always helps to bring fresh eyes to these things. cygnis insignis 13:42, 5 January 2019 (UTC)


 * I don't think so, but if you two like that version, go with it. Chiswick Chap (talk) 13:44, 5 January 2019 (UTC)


 * Over the course of editing this paragraph, the meaning has changed. "A short pedalium or stalk hangs from each of the four lower corners, as well as one or more long, slender tentacles." implies that a tentacle (or tentacles) and a pedalium are both attached to each of the four lower corners. The wording we're toying with implies that from each corner hangs a pedalium, and it is to the pedalium that one or more tentacles are attached.
 * If the tentacles are attached to the pedalium, here's the plural jellyfish version:
 * Box jellyfishes are largely similar in structure, with one or more long, slender tentacles borne by a short pedalium, or stalk, hanging from each of the four corners of their squarish, box-like bells.
 * I'm no expert, so I'd rather not fiddle with the meaning without confirmation from someone in the field. Tgroch (talk) 00:32, 6 January 2019 (UTC)
 * , being an expert may help, but it possible for us to resolve this anyway. What is improved here also needs to be improved at box jellyfish, which it appears to duplicate. I could be mistaken, but content was added to that article by . This message will notify the user, we can compare the source with what we have in both articles, and see what hangs where. cygnis insignis 01:19, 6 January 2019 (UTC)
 * I didn't get a ping to this discussion, just saw it on my watchlist. As you say, I added this information to Box jellyfish in 2015. It attempts to describe the animal's anatomy in a straightforward manner, and looking at it now, I see no reason to revise it. Cwmhiraeth (talk) 11:34, 6 January 2019 (UTC)
 * , I messed up the template, which has a bug or feature, apologies for that. I guess if the near duplicate is fine with the that is the end of it, I thought there may have been something lost when it was copied over. Have a good one. cygnis insignis 11:51, 6 January 2019 (UTC)

Sigh. The tentacles are attached to the pedalium. Wording tweaked, Ref added. Chiswick Chap (talk) 09:39, 6 January 2019 (UTC)


 * , u ok? don't forget to update the duplicate text, if you haven't done so already. Are you planning to take this to FAR? cygnis insignis 11:10, 6 January 2019 (UTC)
 * Eh? The text at box jellyfish isn't a duplicate and appears to be correct. I'm not taking anything to FA. Chiswick Chap (talk) 11:59, 6 January 2019 (UTC)

 * Mechanical issues


 * Jellyfish in large quantities can fill and split fishing nets and crush captured fish.[133] They can clog cooling equipment, disabling power stations in several countries; jellyfish caused a cascading blackout in the Philippines in 1999,[123] as well as damaging the Diablo Canyon Power Plant in California in 2008.[134] They can stop desalination plants and ships' engines.[133][135]

 * Mechanical issues


 * Jellyfish in large quantities can fill and split fishing nets, crushing and stinging the fish inside. Often the crushed or stung fish are discolored or not fresh enough to sell when they arrive at the market, reducing or negating their market value entirely. Jellyfish also contribute to overfishing practices by eliminating populations of fish and reducing the amount of available product, encouraging further fishing in order to replace damaged product. A massive amount of jellyfish in nets can also occasionally serve as a sort of anchor, rendering the fishing boat immobile until the nets are cut or the jellyfish are removed.


 * Along with damage to the fishing industry, jellyfish often cause power outages and damage to desalination plants. In 2003 jellyfish blocked the pipes of a desalination plant in Oman, cutting off the water supply to the local population by 50%. Intermittent electrical outages in Sweden, Scotland, the Philippines, Tokyo, and California are caused when jellyfish are sucked into cooling intake pipes and cooling systems. This often causes further problems due to lack of air conditioning and refrigeration in warmer climate. Jellyfish congregation near cooling intake pipes may be due to ocean warming and an influx in phyto and zooplankton. Currently there are no preventative measures for jellyfish power outages or damage to desalination plants.}}

"Jellyfish have a complex life cycle: the medusa is normally the sexual phase, which produces planula larva that disperse widely and enter a sedentary polyp phase before reaching sexual maturity."

or something similar. The text as currently written is confusing (and arguably grammatically broken) and requires reading the 'life-cycle' section of the article to understand. 240D:0:514F:7300:A4EE:2EDE:659C:FB10 (talk) 02:56, 24 September 2020 (UTC)

Deepest Jellyfish Ever Recorded - Article Published
Just FYI -- Our science team just published a peer-reviewed article documenting the deepest species of jellyfish ever recorded, as part of our ongoing "Ring of Fire" expeditions undertaken by Caladan Oceanic in partnership with Dr. Alan Jamieson (Chief Scientist on the expeditions) from the University of Western Australia. The photo were taken by the submersible Limiting Factor or one of its three accompanying landers.

Change: "There are over 200 species of Scyphozoa, about 50 species of Staurozoa, about 20 species of Cubozoa, and the Hydrozoa includes about 1000–1500 species that produce medusae, but many more species that do not."

To: "There are over 200 species of Scyphozoa, about 50 species of Staurozoa, about 50 species of Cubozoa, and the Hydrozoa includes about 1000–1500 species that produce medusae, but many more species that do not."

Via this source listed on the Cubozoa page under Taxonomy, I believe the number of species in this article is outdated and should be updated to 50 instead of 20.
