Moon jellyfish (Aurelia aurita) disturbing the top water layer of Gullmarn fjord at Sämstad, Lysekil Municipality, Sweden.
Summary
[edit]
| Description |
English: Moon jellyfish (Aurelia aurita) 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". It's a quite small and young jelly, about 5–6 cm (2.0–2.4 in) in diameter. |
