NATURAL HISTORY MUSEUM - UNITED KINGDOM : ON SO MANY JELLYFISH : THEY ARE OLDER THAN THE DINOSAURS

NHM - UK : JELLY FISH 

I think jelly fish are so beautiful and - usually - graceful. This web site has some excellent photographs, illustrating the diversity of jelly fish beauty!

Excerpt: Jellyfish come in incredible shapes, colours and sizes. Most jellyfishes’ bell-shaped bodies are between two centimetres and 40 centimetres across. However, some species can grow to more than two metres in diameter, with thin trailing tentacles that are even longer than that.

Jellyfish have radial symmetry, meaning that if you sliced a jellyfish down the middle, the parts would be symmetrical, like the segments of an orange.

These cnidarians are famous for their stinging abilities. The intensity of the sting varies by species.

Some jellyfish can also generate their own light, called bioluminescence – further adding to their otherworldly beauty.
