Welcome to Litsy!

The seas of our planet cover more than 70 per cent of the Earth, yet we know less about the ocean depths than the surface of the moon. Join marine biologist and fish-fanatic Tom "The Blowfish" Hird as he lifts the lid on a treasure chest of fascinating facts, to reveal just what we do know about what lurks beneath the waves. You'll discover how the unassuming jellyfish can cause an ocean-wide apocalypse, why walruses turn bright pink after a sunbathe, how a shoal of herring breaks wind to escape the jaws of predators, and why an archer fish spits missiles at its prey. From the invisible world of meiofauna living in the sands of our beaches to a cephalopod called the 'Vampire Squid from Hell," Blowfish takes us on an incredible journey as he follows the currents from shoreline to the bone-crushing pressure of the deep sea.
