Jellyfish

Just look at this! Isn’t it an Alien’s spacecraft? May be not, but it is definitely something extraterrestrial, and that is true because giant jellyfish lives in the dark blue depth. As for me it seems like liquid space… fascinated, magnificent and mysterious.
Ok,here are some science now: Jellyfish inhabit in every major water area and has a different sizes, shapes and colors depending on species.

Instead of brain Jellyfish uses elementary nervous net which could react on light, odor etc. Most of them are transparent or semi-transparent because 95% of their body consist of water.
Most of them are harmless, but some are really dangerous even for human life, although all of them eat only zooplankton or, if occasionally other jelly fishes (but mashroom jellyfish is considered as a delicacy by humans).
So, enjoy other pics and send me your comments or links with nice pics of jellyfishes.
