Checked: verified by a taxonomic editorTaxonomy Despite its charismatic appeal to both scientists and the general public, remarkably little is known about the giant squid Architeuthis, one of the largest of the invertebrates. Although specimens of Architeuthis are becoming more readily available owing to the advancement of deep-sea fishing techniques, considerable controversy exists with regard to topics as varied as their taxonomy, biology and even behaviour. In this study, we have characterized the mitochondrial genome (mitogenome) diversity of 43 Architeuthis samples collected from across the range of the species, in order to use genetic information to provide new and otherwise difficult to obtain insights into the life of this animal. The results show no detectable phylogenetic structure at the mitochondrial level and, furthermore, that the level of nucleotide diversity is exceptionally low. These observations are consistent with the hypotheses that there is only one global species of giant squid, Architeuthis dux (Steenstrup, 1857), and that it is highly vagile, possibly dispersing through both a drifting paralarval stage and migration of larger individuals. Demographic history analyses of the genetic data suggest that there has been a recent population expansion or selective sweep, which may explain the low level of genetic diversity.(Winkelmann et al. 2013) [details]

Unreviewed: has not been verified by a taxonomic editorDescription The family includes the largest of all cephalopods. Specimens occasionally are found moribund at the surface of the ocean, but most records are from strandings or whale stomachs. Apparently world-wide in distribution.

Many species have been named in the sole genus of the family, Architeuthis, but they are so inadequately described and poorly understood that the systematics of the group is thoroughly confused. Total lengths of nearly 20 m and mantle lengths of nearly 6 m (not a complete specimen) have been recorded.

Juveniles of species have been reported from both the Atlantic and Pacific Oceans.

The Architeuthidae is characterised by a tetraserial armature on the tentacular clubs with large suckers in the medial rows of the manus and small suckers in the marginal rows; a distinct cluster of numerous small suckers and knobs at the proximal end of the manus; two longitudinal rows of alternating suckers and pads on the tentacular stalks; a straight simple funnel locking-cartilage; buccal connectives that attach to the dorsal border of arms IV; absence of photophores. [details]
