Morphological and molecular description of a new record of Graneledone (Cephalopoda, Octopodidae) in the southeastern Pacific Ocean
Octopuses of the genus Graneledone inhabit in the deep-sea and are composed of 8 recognized species. Here we conduct phylogenetics analyses of 4 species of Graneledone using 2 molecular markers (16S and COI), and report a new record of Graneledone for the Pacific Ocean off south-central Chile. Four...

These octopuses are medium sized, have no ink sac and bear only one row of suckers in their arms, which are of similar length.
