The Imaginarium has been inundated with requests for some of your favourite episodes! Let's dive in...
Up here on land, we breathe air into our lungs but how do fish breathe underwater? Is there air in the sea? Do fish have lungs like us? Let’s head to the beach with Dr Nij to meet marine biologist Tooni Mahto and find out how fish and other sea creatures live underwater.
