Within the different types of existing wetlands, there is also the so-called intertidal area of the ocean, that is, the portion of the beach that becomes covered with water the tide is high, and exposed when it is low. A very particular marine fauna inhabits this area which has adapted to the highly variable conditions of the environment, and that was collected and depicted in a didactic manner in the project entitled Entremareas: la cueca larga del litoral chileno (“Between Tides: the long cueca of the Chilean Coastline”).
It is a “stage-book“ that unfolds and stretches –like an accordion-, reaching almost two meter in length. It depicts the Chilean coast and the species of algae and animals that characterize it in colorful watercolor illustrations. The illustrations by María José Carmona are accompanied by poetry in the form of a long cueca, written by the Chilean poet Floridor Pérez. The book also shows, on its back, drawings of the species portrayed in the illustrations with their respective scientific information, inviting the reader to paint, observe and recognize them.
Entremareas: la cueca larga del litoral chileno is the third book from the Editorial Ciencia & Vida publishers, which belongs to the Fundación Ciencia & Vida, and was supported by the Fundación Cosmos. The collaboration of both foundations has allowed for the donation of 1,000 copies to schools, families and institutions throughout Chile. The book will also be available in the country’s main bookstores.
The project was supported by Juan Carlos Castilla, an ecologist who was awarded the National Award of Sciences, as the scientific editor; Daniela Correa, head of culture and communications of the National Library, as poetic editor; and Nikolás Botinelli, musician and vocalist of the group Los Pata e’ Cumbia, who composed the long cueca of the Chilean coastline, from the poetry of Floridor Pérez.
Entremareas also includes the creation of the digital platform www.entremareas.cl, which will provide information and complementary materials on the species, including an animated video of the illustrations, downloadable coloring sheets and links to related selves so that users can delve into the research on this ecosystem.
 The cueca is a traditional Chilean dance and musical style.
