Talk:Movile Cave

Apparent contradiction

Life in the cave has been separated from the outside for the past 5.5 million years...

and

The most recent animal recorded is the cave's only species of snail, which has inhabited the cave for slightly more than 2 million years.

Which is it? – Anne drew 19:58, 15 January 2020 (UTC)

The answer is both. The article states 57 species currently live in the cave. They did not all arrive at the same time. Life first evolved there 5.5 million years ago. Two million years ago the most recent animal evolved or entered the cave. CougarTwoLegs (talk) 22:24, 30 May 2022 (UTC)

Hi CougarTwoLegs. Thanks for your explanation, but the contradiction is not solved: "separated from the outside for the past 5.5 million years" means: no access for new species after that, i.e. not possible for any animal, snail or not, to enter 2Mya. Nonsensical. So Anne drew Andrew and Drew's question still stands. Arminden (talk) 12:52, 23 March 2024 (UTC)

Confusing term, unsourced info

Description

Movile Cave is a network of paths in limestone that are approximately 200 metres (660 ft) long... <Ref: Kumaresan et al. ...>

1. Paths?! Fissures, vertical shafts, horizontal passages, rooms, galleries...?
2. Kumaresan does not mention any cave dimensions. None. So where do the 200 m come from?

Units

The article says:

The lake waters only contain as little as 1 mm of dissolved O₂, and up to 1 cm of dissolved O₂ at most.

A millimetre or centimetre of dissolves oxygen makes no sense at all, so I can only guess it's supposed to mean mmol(·L^-1) and cmol(·L^-1). If someone can confirm this, I'll change it. JTonic (talk) 12:22, 7 October 2025 (UTC)

I just saw this. Checked this source, https://pmc.ncbi.nlm.nih.gov/articles/PMC6697535/; it says 9–16 µM at the surface; <1 µM below 3–4 cm. It it cited by another source. I think it should be changed User:JTonic - User:Yeysus 17:10, 12 October 2025 (UTC)

Ok I am going to edit that now. User:Yeysus 11:39, 18 October 2025 (UTC)

Thank you! Lost track of this somehow. JTonic (talk) 21:14, 21 October 2025 (UTC)

Sealing

The article doesn't say anything about HOW the cave came to be sealed. This seems to be a pretty important piece of information considering that most of the cave's interesting features are a result of it being sealed for so long Science Is My Life (talk) 06:48, 17 December 2025 (UTC)

probably happened in the same way that caves naturally form, because of the sea ~2026-33245-63 (talk) 02:27, 5 June 2026 (UTC)

A "Caves with chemosynthetic ecosystems" is needed

Caves with chemosynthetic ecosystems: we need such an article. Repeatedly listing "similar caves" on the Movile Cave page and other pages is not economical.

Sorry, I started creating one, something happened and all my work got lost. No time to start again. Anyone?

I had used as a base part of the structure and material of this page, adding links like food chain, trophic level etc.

After a definition and short explanation, a bulleted list should follow. Once the topic evolves, sections on different types can be added.

Movile was the first one identified as such, with other caves - either already known but whose chemosynthetic ecosystems had not yet been identified, or freshly discovered ones - following in ever faster succession. F. Por's "Ophel biome" theory should be included here, as it offers an explanation for the obviously widespread phenomenon.

Cross-referencing is essential: links, hat tags, "See also", etc.

Good luck! Arminden (talk) 16:33, 13 June 2026 (UTC)
