Heart of the Ocean Screensaver

Despite their plant-like appearance sea anemones are actually animals and believe it or not, they have a 'foot'. Not a foot like yours or mine but a sticky 'pedal disc', allowing them to hang on tight, move location and even swim. Though, the colorful tentacles hide a deadly secret... neurotoxic venom, meant to paralyze and kill their living prey, luckily, it's not toxic to humans. Like an alien out of a sci-fi novel sea anemone tentacle can grow back and laughably, their mouth is in their anus. According to scientist's sea anemone can live longer than one hundred years.
