Molecular evolutionary relationships of the octopodid genus Thaumeledone (Cephalopoda: Octopodidae) from the Southern Ocean
Abstract Recent trawling in the Southern Ocean has yielded individuals of a number of species of the deep sea octopod genus Thaumeledone. This paper provides the first molecular study of the genus, employing molecular sequences from five mitochondrial (12S rDNA, 16S rDNA, COI, COIII, cytochrome oxid...
