Hairy lobsterThe long, deep harbour on Ambon Island is one of the top muck diving destinations in the world, a type of diving that puts the focus on bizarre marine animals – such as frog fish and other masters of disguise like snake eels and stargazers – that make their homes on the ocean floor. People travel to this island from around the world to dive the harbour’s nutrient-rich, if rubbish-littered, ocean floor. This hirsute, wild-looking purple creature is a hairy squat lobster; the bristles covering its body help it to better scurry across sponges. (Chris Jackson/swellimages.com)
