The manatee (Trichechus manatus) is an endangered herbivorous aquatic mammal, which has coastal habits and is distributed from the southeastern United States to the northeastern coast of Brazil. Although the evaluation of their eating habits is consolidated, there are data available on the nutritional composition of foods consumed in wildlife. Considering this fact, the present study aimed at the nutritional composition of the antillene manatee diet, in situ, in conservation units of the Paraíba coast. A total of 31 food items and 20 faecal samples of manatee were collected from the Environmental Protection Area of the Barra of the River Mamanguape and Area of Relevant Ecological Interest Mangrooves of Foz of the River Mamanguape, during two periods of the year (rainy and dry). The food components were submitted to determination of dry matter, neutral detergent fiber, acid detergent fiber, crude protein and mineral matter. As fecal samples were submitted to the qualitative identification of taxonomic group and solid residues. Samples of algae (n = 4), marine angiosperm (n = 1), fragments of plastic bag (n = 6), nylon thread (n = 1), nylon rope, plastic twine (n = 1) and unidentified plant structures. A nutritional composition of food items for scientific literature, except dry matter and mineral matter. This work may support future studies on the nutritional requirements of non-Brazilian manatees and assist in the elaboration of maintenance diets for animals and management plans
