The Dancing White Lady is a great, big spider from the Namib Desert in southern Africa.

They spend their days hidden in underground burrows and emerge at night to hunt for insects and lizards which they find by detecting the vibrations of footsteps.

These hunting expeditions occur within a short range of the burrow entrance, but males can travel over 100 metres in search of a mate.

He communicates with the female via the timeless medium of dance. Tapping the ground outside her burrow sends down vibrations that ask her to come out, but not eat him. She doesn’t always oblige…

Heaven has chubby, rosy-cheeked cherubs fluttering through blue, cloudless skies on improbably tiny wings.

Hell has Armoured Searobins crawling on mud and rock with their four, spindly fin spines.

These fish get their name from the bony scutes that cover their body. They live fairly deep in the sea, and find prey by scouring the ocean floor with their elaborate barbels.

Fishermen sometimes catch them, and then have absolutely no idea what on earth they’re looking at.

You can’t blame them. No-one really knows what a demon looks like.

Here’s a sweet little siphonophore bobbing around in the deep sea!

Siphonophores are members of the phylum Cnidaria, like jellyfish, sea anemones and corals.

They’re colonial animals. What you see here is not one, single individual, but an entire army of sea anemones and jellyfish all stuck together.

The sea anemones (or polyps) are at the bottom and use their stinging tentacles to catch food.

The jellyfish (or medusae) are at the top, where they pulse and beat away so that the whole gang can get around.

The Golden Horde is back! And this time they’re kinda cute.

Acorn Worms are a class of marine worms that were long thought to be members of the phylum Chordata, alongside all the vertebrates and such oddities as sea squirts and salps.

They’ve since been placed within a phylum of their own called Hemichordata, and the evidence now suggests they’re actually more closely related to echinoderms.

For the longest time all known Acorn Worms lived in burrows in shallow water, where they consumed detritus and went largely unnoticed.

That all changed when we acquired the technology to take a really good look at the bottom of deep sea environments. In turns there’s entire family of Acorn Worms down there! They’re much more colourful and conspicuous than their shallow-water kin, and spend their time crawling around eating the ooze beneath them.

They don’t burrow, but they do use a bubble of mucus to rise up from the seabed and drift on the currents to find new feeding grounds.

That’s why I love the deep sea. It’s a place where worms can fly!
