Summary

Description
English: A lion's mane jellyfish ephyrae form between two medusas. The ephyrae is between a small lion's mane jellyfish (Cyanea capillata) and a moon jellyfish (Aurelia aurita). The moon jelly has just been captured by one of the lion's mane's tentacles. The jelly medusas are still quite small, about 5–6 cm (2.0–2.4 in) in diameter. In Gullmarn fjord at Sämstad, Lysekil Municipality, Sweden.
The jellies are disturbing the top water layer of the fjord. 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".
