The red octopus Octopus maya Voss et Solís-Ramírez, 1966 is an endemic species and one of the most important fishery resources of the Yucatán Peninsula, Mexico. Due to its economic importance and the fact that in recent years interest in farming this species has increased, several initiatives have been implemented to study its biology and requirements for cultivation. Parasites represent an important component of the biology of the red octopus, as they can have an impact on both wild and cultivated populations. A total of 44 O. maya specimens were sampled from the fishing ports of Ría Lagartos and Dzilam de Bravo, Yucatán; specimens were measured and subsequently subjected to histological analysis of the buccal masses where cestode larvae (Prochristianella sp.) were found in the anterior salivary glands. Results of a chi-squared test showed that specimen size class and infestation levels (parasite abundance) were significantly correlated, with parasite damage levels more pronounced in larger animals. The damage caused to the anterior salivary glands by this parasite could have serious implications for feeding and reproductive success of O. maya.
