Abstract
Two new species of the genus Octopus, discovered in the shallow water of the southern Caribbean, are described. Both octopuses are common in the local artisanal fishery. Octopus tayrona n. sp. is characterized by having 112 to 135 suckers on hectocotylized arm, a small ligula (LLi 0.42–1.62) with a calamus about one third to one half the length of the ligula, and ctenidia with 9–12 lamellae per demibranch. Octopus taganga n. sp. is characterized by having an ocellus between arm II and III, 80–85 suckers on the hectocotylized arm, and ctenidia with seven to ten lamellae per demibranch. A comparison with similar species is included.
