"There are Cities Underwater" is a partnership between Cidades Debaixo de Água in Portugal and Oceanus Conservation as a guest author. Hippo, a seahorse explorer, wanders around the ocean and finds himself in the mangrove forests in the Philippines. Hippo takes us to see the different animals living in this habitat and the importance of mangroves to us and the environment. With science-based facts, children age 10+ above will surely learn something new.

Suggested age: 10 years old and above

The project, “There Are Cities Underwater,” began in 2020 through an invitation to build an educational program for the exhibition “The Sea is our Land” in cooperation with the Cultural Center of Lisbon. The team decided to put together 5 children’s books, each one dedicated to a different marine ecosystem namely the seagrass meadows, rocky reefs, kelp forests, coral reefs, and mangrove forests. The idea was to educate both children and their parents of each one's biodiversity and current threats.

The project is built on 3 principles - Education as a tool for conservation; Local action for a global project; and Ocean literacy valuation. It is our vision that our books can promote environmental education and ocean literacy not only in Portugal, but in all the corners of the world where a marine ecosystem exists. We want to make the ocean and its conservation a fundamental part of everybody’s daily life and knowledge.
