Animal that blinds its prey
|
view preview
The Dana octopus squid ( Taningia danae) of the Pacific blinds its prey with flashes of light from its arms! It is believed that this highly maneuverable squid uses the bright flashes to disorientate potential prey. These flashes may also serve to illuminate the prey to make for easier capture as well as a courtship and territorial display.

Spitting fish
|
view preview
Why do these fish look like they’re spouting puffs of magic dust out of their mouths? The tiny crustaceans (1 millimetre-long crustacean called an ostracod) that these transparent fish try to eat light them up, causing the fish to be at risk of predation themselves, so they spit them out! ...

Oldest freshwater lake on Earth
|
view preview
Lake Baikal in eastern Siberia is the oldest freshwater lake on Earth, and one of the largest and deepest, containing around one-fifth of the world's freshwater. In winter, it freezes over, and these beautiful transparent, turquoise masses of broken ice appear momentarily in March, caused by the unequal structure, temperature and pressure in the main body of the packed ice.

A fish that doubles as a camera stand
|
view preview
Found all around the world, including off the coast of Australia, the tripod fish can live in depths of up to 6 km below the surface. The purpose of those super-long fins is to elevate the tripod fish to about a metre above the seabed, where the ocean's current is strong. This means that small prawns and crabs are ushered right into the tripod fish's gaping mouth, and all it has to do is stand there.

Metal-coated animal
|
view preview
This little guy on the left is the iron sulphide secreting scaly-foot gastropod. It's the only animal known to plate itself with metal and lives in a thermal vent deep in the ocean. But last year scientists found a pale, genetically identical version of the species (on the right) that doesn't secrete metal, leading scientists to question what the purpose of the armour really is.
