Welcome to the adventure through the marine food chain!

Come and join Danny the Dolphin, and his friend Wade the Blue Whale as they explore how animals survive and grow in the food chain.

Find out why Wade, the largest animal in the world, eats krills, one of the tiniest group of animals in the sea!

Readers will also discover the effects of pollution on the food chain, and why so much of the food that Wade, Danny and other animals depend on is disappearing.

This educational journey details how we can all help to protect the sea, so humans and sea animals can have delicious, nutritious food and a clean sea to swim in.
