These monster fish break all convention. They're all fish, but they're not normal. These are the freaks of the world's oceans.
Some, like the Monstermouth (Sarcastic Fringehead) are totally out of proportion. The biggest mouth in the Pacific Ocean.
It's a crazy sight, an innocent looking fish unleashing this X-men like power as its whole head dislocates and its jaw pops forward in a purple wall.
Anyone thinking of intruding on its territory thinks twice.
Others like the Frog Fish have lost almost all their swimming skill. Shuffling across the sea bed like a formless blob of play-dough as it uses its pectoral fins to walk.
The Wolf Eel has a crazy set of jaws and teeth, and must have the toughest face of all fish. It eats spiny sea urchins for breakfast – imagine biting down on a ball of needles every time you're hungry?
The Slime Fish (Hagfish) is possibly the least lovable fish in the ocean; they exude a bucket of noxious slime if they feel threatened.
The slime contains tens of thousands of very thin (100 times smaller than a human hair) protein threads, which are extremely strong.
This slime helps them escape from predators by clogging the gills of their attackers.
And beneath the waves lives the second-most poisonous vertebrate in the world, after the golden poison frog, The Balloon Fish (Pufferfish) contains deadly Tetrodotoxin in its skin and organs, and has many more defence mechanisms to boot.
They can move their eyes independently, change colour or the intensity of their patterns to match their environment.
And if all else fails, once threatened this freaky little fish fills its extremely elastic stomach with water until it nearly triples in size.
It's unbelievable that the Sunfish (Mola Mola) can swim at all. This swimming space ship is the world's heaviest bony fish.
It has more than 40 species of parasites living on their skin, so they spend their time basking on their sides at the surface being cleaned by wrasse, sea birds and reef fish.
This is a glimpse of nature like you've never seen her before. Enter the dusty house of horrors and discover a world of Incredible Fish.
The Cube 7
Welcome to The Cube - a format in which just seven simple physical and mental challenges stand between the contestant and £250,000.
The challenges appear to be easy, but games become fraught with extraordinary pressure and tension when played inside The Cube.
'The Body', the mysterious master of The Cube, shows each contestant that every challenge is possible - but it's not easy when you are in there, under the spotlight...
Tasks include Trajectory, Equilibrium, Shatter, Contact, Memorise - and none are simple once inside this high-pressure claustrophobic world.
The Cube offers two life-lines - one is to Simplify a challenge and the other is Trial Run, where the contestant gets to try the challenge before committing to gamble their winnings on completing it for real.
Do you have the skill, strength and nerve to keep mind and body focused and beat The Cube?
