Whether in the crystal clear waters of the Caribbean or off the coast of Australia and Tasmania, some of the world's most beautiful oceans also contain the world's most nightmare-inducing creatures. Often dwelling at the bottom of the sea and rarely seen by humans, Distractify compiled a list of the creepiest underwater animals around.Behold the best of the bunch and good luck getting into the water after this.The goblin shark is a deep-sea dwelling animal with a whole lot of very sharp teeth. Thankfully, it poses no threat to humans as it mostly eats bottom-feeding fish.While very little is known about the elusive creature, it is believed to have a wide global distribution having been spotted everywhere from the Gulf of Mexico to Japan. The sarcastic fringehead may have a chuckle-inducing name, but this tiny, ferocious fish is no joke.Known for its large mouth and territorial behaviour, they are ambush feeders and aggressively attack their prey - usually crustaceans.They are native to Southern California and Baja, Mexico.   Good luck ever being able to close your eyes again after getting a glimpse of the world's toughest creature: the water bear (or tardigrade).The water-dwelling micro-animals are classified as extremophiles, which means that they can thrive in an environment that would be detrimental to most life on Earth.No wonder they can live for up to 200 years and survive trips to space.(dailymail.co.uk)Bakudaily.Az
