The life-span of members of the Octopodidae varies between about 6 months in small tropical species to four years in cold water species such as Bathypolypus arcticus (O'Dor and Macalaster, in Boyle, 1983).
(Cephalopoda: Octopodidae), a new shallow-water octopus from tropical Australian waters.
Ocellate octopuses (Cephalopoda: Octopodidae) of the Great Barrier Reef, Australia: description of two new species and redescription of Octopus polyzenia Gray, 1849.
The "Par-" may suggest a close relationship and I know that according to morphological data they constitute the subfamily Eledoninae (Sweeney and Roper, 2001), but has their relationship ever been verified by genetic studies?
Evolutionary relationships of Southern Ocean Octopodidae (Cephalopoda: Octopoda) and a new diagnosis of Pareledone.
Janet Voight put out a very interesting paper a decade-or-so ago (could be longer; could have been near 2 decades - maybe 1988 in Malacologia; I'm getting older and time flies) on arm sucker number (and row - 1 row or 2) in octopodids (Octopodidae).

An important finding is the failure of the molecular data to support the monophyly of the Octopodidae.
This family contains over 90% of the species in the Suborder Incirrata, and has always been difficult to define.
Statistical tests constraining Octopodidae monophyly using parsimony and maximum likelihood techniques suggest that all Incirrates may be derived from octopodids.
