This article analyzes the treatment of the phylum Cnidaria in high school biology textbooks, discussing the results in light of the environmental history of the Brazilian northeast coast and the coloniality of knowledge in the production of school knowledge. This is a qualitative and documentary study, whose corpus consists of six textbooks approved by the National Textbook Program (PNLD), analyzed according to criteria related to theoretical content, historical contextualization, and the valorization of Brazilian biodiversity. The results indicate the predominance of descriptive and fragmented approaches, with a strong emphasis on foreign examples, especially Australia's Great Barrier Reef, to the detriment of Brazilian reefs. There is also a lack of discussion about the biomineral exploitation of corals during the colonial period. In light of the paradigm of complexity and decoloniality, it is argued that this omission contributes to the erasure of the biological, historical, and environmental dimensions of corals in biology education.
