The deepest sea
"Sunlight reaches only about 200 metres below the surface of the sea. Below that, the light fades until there is total darkness. Despite the darkness, here we find the homes of some extraordinary creatures, including fish that create their own light and seabed animals that look like feathery plants."--Back cover.
