We’re cracking open the Squiz Kids vault this week to bring you back one of our most mind-bending episodes — the Shortcut to the Deep Sea.

It’s a place where sunlight never reaches, creatures glow in the dark, and survival means adapting to some of the toughest conditions on Earth. In this episode, we explore what lives deep beneath the ocean’s surface, how these animals survive, and why scientists are still uncovering new discoveries down there.

Strange, surprising, and still full of mystery — the deep sea is a world like no other.
