Original –Moon jellyfish disturbing the top water layer of Gullmarn fjord at Sämstad, Lysekil Municipality, Sweden. The photo was taken on a calm, sunny morning after a rain, so it's likely that the layer is warmer water with some freshwater added. In this case that would make a thermocline coincide with a halocline and resulting in a very thin but visible pycnocline. This difference in density and the altered refractive index is what makes the water look "oily". —image description on Commons

Reason: it is a high quality pic and one of the only ones that shows the subject as it appears in real life (rather than a diagram)

Support – a natural depiction of a density gradient phenomenon caused by salinity and temperature variations. Bammesk (talk) 03:46, 18 July 2020 (UTC)[reply]
Oppose Illustrates phenomenon well, but jellies are not in focus. Charlesjsharp (talk) 06:59, 18 July 2020 (UTC)[reply]
Weak support for the EV alone regarding a high difficulty subject. It's a blurry mess at full res. MER-C 16:01, 19 July 2020 (UTC)[reply]
