Our world is full of big stuff.
We've had giant tortoises, 5m-tall ancient rhinos, huge newly discovered rodents, great white sharks and even long-lost giants from Earth's past.
Here at BBC Earth, we had a lot of fun with all these giant stories. So why don't you join in and send us your pictures and videos of really big things.
We want your shots of big wildlife, big nature, big waterfalls, big skies, big mountains and those big Earth moments that simply took your breath away.
Interpret the challenge however you wish. Show us your skills, experiences, and celebrate life on this planet. It's up to you.
We will share the best contributions on BBC Earth and on our Facebook, Instagram and Twitter accounts, where you can share and comment on each other's work, and use the hashtag #EarthCapture.
