Some interesting takeaways::<p>- The cave is called &quot;Movile&quot;.<p>- 3 species of spider, a centipede, 4 species of isopod (the group that includes woodlice), a leech never seen anywhere else in the world, and an unusual-looking insect called a waterscorpion<p>- Movile&#x27;s only snail [probably the only snail <i>species</i>] suggested that it has been down there for just over 2 million years.<p>- Many animals are born without eyes, which would be useless in the dark. Almost all are translucent as they have lost pigment in their skin.<p>- The cave seems to have no contact with the surface; Chernobyl accident had released lots of radioactive metals, which had found their way into the soils and lakes surrounding Movile Cave. However, a 1996 study found no traces of them inside the cave.<p>- The ecosystem seems to be supported by <i>chemosynthesis</i>; bacteria oxidise methane, sulphide and ammonia, generating energy and organic matter.
