Cassiopea
Cassiopea (also: mangrove jellyfish ) is a genus of umbrella jellyfish. These jellyfish are found worldwide and are often found in shallow, vegetated by mangrove seas. There they hold primarily on sandy or overgrown by seagrass areas. Most often you meet them there in larger groups.
Special
The mangrove jellyfish is in English also Upsidedown Jellyfish (about: standing on the head jellyfish ), because it is not like other jellyfish, tossed about by the sea currents, but is permanently set on the seabed. The tentacles are facing upward toward the sunlight, the jellyfish is upside down. In addition, this species lives in symbiosis with algae, which are in the tentacle tissues and operated through photosynthesis. Although mangrove jellyfish have stinging cells, but these are primarily the defense and can cause mild itching and skin irritation in humans.
