Mexican Four-eyed Octopus

Campeche Bank is located off of the Yucatán Peninsula in the Gulf of Mexico. It extends about 125 miles (201 km) into the Gulf where it suddenly drops off, ending at the Alacran Reef. There are very low levels of sediments along the Bank between the shore and the reef. The benthic environment in this region can be characterized by fine carbonate sand. The strong currents the flow westward along the bank year round likely contribute to the nature of the benthic sand and lack of sediments.

Octopus maya is known to feed primarily on benthic prey such as crustaceans, bivalves, fish, gastropods, other octopuses, and even birds. Two specific prey items that O. maya commonly feeds on are blue crab (Callinectes sapidus) and the crown conch snail (Melongena corona bispinosa). Neurotoxins in O. maya's saliva cause temporary paralysis in its prey, allowing for easier consumption. This paralytic also works on conspecifics, leading researchers to believe that it is used in territorial defense as well as intraspecific competition. Beyond the chemicals found in their saliva, not much is known about hunting techniques specific to O. maya. However, looking at sister taxa, including the closely related Common Octopus (Octopus vulgaris), can shed some light on likely mechanisms used by O. maya. O vulgaris has been observed using its strong suckers to restrain its prey, while carrying the victim toward its mouth. The octopus can then inject the organism with saliva, drilling holes into the bodies of shelled organisms such as crabs and bivalves using its beak as necessary, and consume its prey.
