  OCTOPUS - LoveToKnow Article on OCTOPUS
The usual species of Octopoda on the British south coast is Eledone cirrosa, which has only one row of suckers on each arm, and is a smaller animal.
The octopus and many of the Octopoda move about by means of their arms on the sea bottom, and are not free-swimming, though like other Cephalopods they can propel themselves on occasion backwards through the water by means of the funnel.
Other Octopoda, however, are pelagic and free-swimming, and such habits are not confined to those forms which are provided with lateral fins.

 Octopus - Wikipedia, the free encyclopedia
The octopus is a cephalopod of the order Octopoda that inhabits many diverse regions of the ocean, especially coral reefs.
The Oxford English Dictionary lists octopuses, octopi, and octopodes (the order reflecting decreasing frequency of use), stating that the last form is rare.
The term octopod (either plural octopods and octopodes can be found) is taken from the taxonomic order octopoda but has no classical equivalent.

Two lineages are recognized within the Vampyropoda; the Vampyromorpha Grimpe, 1917 and the Octopoda Leach, 1817.
Stratigraphically younger forms from the Late Cretaceous of the Lebanon show a slight gradational differentiation of the arms; the dorsal arms are the longest and the ventral arms the shortest.
Proteroctopus ribeti Fischer and Riou is the most primitive octopod, or might fit within the stem-lineage of the Octopoda or be a fossil vampyromorph (Engeser 1988).

Naef (1923) felt that the origin of the Octopoda would "forever be obscure." But Naef was unaware of the significance of Vampyroteuthis which was believed to be a cirrate octopod at the time.
We now know that the Vampyromorpha is the sister group of the Octopoda and that Vampyroteuthis provides telling clues to the origin of the octopods.
(1999) argue, therefore, that the benthic habitat was the primitive one within the Octopoda and that pelagic species, which comprise nine of the eleven octopod families, are secondarily pelagic.

In this paper we examine the phylogenetic relationships of the Octopoda utilizing molecular sequence data from the cytochrome c oxidase subunit I (COI) gene and compare results from analyses of molecular data with classifications and phylogenies based on previous morphological studies.
Partial COI sequences (657bp, excluding primers) were obtained from 28 species representing most of the diversity in the Order Octopoda, along with a sequence from the established sister-taxon to the Octopoda, Vampyroteuthis infernalis.
Statistical tests constraining Octopodidae monophyly using parsimony and maximum likelihood techniques suggest that all Incirrates may be derived from octopodids.
