Finding Nemo??

Even I failed..
yes, its a Sea anemone but there is No Nemo(Clown fish)

Sea anemones are Corals (soft corals to be specific)

Anemones have a cylindrical body, with an oral disc mouth and tentacles surrounding it, and an adhesive ’foot’ for holding onto rocks and coral. It is hence, a normal polyp shape. The tentacles have a unique cell on the end of each called cnidocytes. Cnidocytes have cnidae that have nematocysts which are the ‘stingers’ that hold the poison that defends and feed the anemone. These poisons or ‘toxins’ are named actinoporins, and are actually a sensitive hair that releases the poison cells at the moment of contact. These toxins contain neurotoxins, which are the paralytic addition to the poison these actinoporins excrete.
Anemones also contain a simple gastrovascular system. This gastrovascular system includes one stomach. The sea anemones anus acts as its mouth as well. The anemone is unique in that, for all its complexities, it's quite simple.
