Known to have the strongest grip of all animals, these crabs can open up coconuts, eat just about anything – including their own moulted shell – and are a bit of a kleptomaniac. They will steal dishes from your house just for the heck of it!

If you thought grabbing that coconut crab was fraught with danger, try this… these crabs grow up to 3 feet in size!! They can scare the heck out of a dog!!
