Photographer's Note

Jellyfish is plentiful around Lebanon coast line. Lebanese are very familiar with this creature, especially on the beach during summer. Almost every 5 minutes you'll see someone grabbing a Jellyfish out from the water to the sea shore. Some Jellyfish are big as almost one meter in diameter and some are medium in size as this one in the photo.

Some facts:

jellyfish is that they don’t have any brain, heart, or bones. Some jellyfish have ways of detecting obstacles that can be compared to sight but they don’t have real eyes. It is a mystery how they can process the information from their “sight” since they doesn’t have any brain. They react directly on food and danger stimuli via nerve impulses without having any brain to process the impulses. Another fact about jellyfish and their bodies is that the body consists of over 95% water.

Jellyfish use tentacles with stinger cells to catch their prey, typically plankton and small fish. (The exact prey depends mainly on the size of the jellyfish.) The tentacles transport the prey they killed with their stingers to the mouth and the jellyfish promptly devours the animal. It is the same stinger cells that stings humans that ventures to close.

Jellyfish go through several stages during their lifecycle and the form that you usually associate with jellyfish, medusas, is only one of them. There is for instance a phase called planula, where the jellyfish is in a type of larval stage. The planulae eventually attach themselves to surfaces where they become polyps which later turn into to medusas.
