English: Lion's mane jellyfish (Cyanea capillata) in Gullmarn fjord at Sämstad, Lysekil Municipality, Sweden. This specimen is about 10–12 cm (3.9–4.7 in) in diameter and the tentacles are about 60–80 cm (24–31 in) long. It is photographed from a jetty. The color of the background is made up from algae on the bottom (green), reflection of the sky on the surface (blue) and shadows from boats nearby and objects on the bottom (black). As the jellyfish moved in the water along the shoreline, the surroundings changed color.
