In the oceans of our planet lurk creatures weirder than our wildest dreams or our scariest nightmares. Multi award-winning underwater cameramen John Boyle and renowned Red Sea specialist John McIntyre have collaborated to produce this wide ranging blue-chip television special, filmed over several years, portraying some of the strangest underwater creatures from every corner of the planet. Among the creatures featured is one of the world's longest animals, a strange snake-like jellyfish which can grow to well over 40 metres and has deadly stinging cells all along its body - yet it doesn't even have a brain, the cannibalistic squid, shark that can only walk on the seabed and the supremely ugly frogfish, which strikes quicker than almost any other fish in the sea.
