The way hundreds of fish move together may help with the design of wind turbines. Schools of fish appear to move as one - turning, contracting, expanding, even parting and then coming back together again. This is a beautiful sight. Scientists have been studying them to try to make wind farms more efficient.

It blasts a toxic spray at predators. Now this beetle may help cars become more fuel efficient. The bombardier is the species of beetle that even sprayed acid in Charles Darwin’s mouth. The 'biological cannons' may help in the design of powerful fuel injection systems.

Imagine flapping your arms and flying. Could we do that based on how the bat does it? Leonardo Da Vinci was fascinated by the flight of bird and bats and used to sketch ideas in notebooks for a flying machine called the Ornithopter.

How can we prevent millions of birds from being killed by flying into windows? The solution could rest with spiders. Webs containing UV reflective threads deter birds from colliding with them. With Patrick Aryee.

The shape of flippers may help with the efficiency of wind turbines, thanks to humpback whales. Bumps on the edge of their flippers assist them, as they power through water. Biologist Frank Fish discovered this when he saw a sculpture.

How do geckos walk up walls and across ceilings? It is all down to the hair-like structure on their feet. A sticky material based on these clever lizards could help us grab debris in space!

Meet the spider-inspired robot that one day might just save your life. Based on how spiders move, it could get to places too difficult for a rescue team to access. Just like our eight-legged friends, it can squeeze around obstacles and through small spaces.

Millions of ridged scales make it difficult for bacteria to attach to the skin of a shark. Can we reduce infections and fight superbugs in a similar way? Have a look at our beautiful animation to see how the shark’s scales or ‘denticles’ work: www.bbcworldservice.com/30animals

Imagine a drone that can fly like the Wandering Albatross. The huge bird harnesses power from the wind and sun and glides over the sea. It is extraordinary. And an engineer has designed a robotic glider that can also ride the wind, while surfing the waves like a sailboat. With Patrick Aryee.

It performs headstands in a desert; now this beetle is teaching us how to collect water. The Stenocara beetle survives in one of the most arid places in the world – the Namib Desert in southern Africa. Scientists have been studying its wings and back.
