The numerous MD 50 specimens (Fig. 13A–B) measure up to 11.8 mm dd and have the thin ovalto-trapezoid perforated unfragmented DAPs that cover the vertebrae that are diagnostic for the O. vivipara - O. serpentaria Lyman, 1883 complex of species (see Mortensen 1933c, fig. 1–2). Analysis of COI sequences (O’Hara et al. 2014), showed that O. serpentaria specimens from the North Atlantic form a distinct clade to O. vivipara , as do populations from subtropical SW Australia and NE New Zealand, but O. vivipara sequences from the Falkland Islands, Tristan da Cunha, South Africa, Coral Seamount on the SW Indian Ridge, SE Australia, New Zealand and the Macquarie Ridge were not distinguishable. However, there are inter-population differences in life history. Specimens from off South America brood juveniles in their bursal sacs but specimens in other regions do not (Mortensen 1933c, 1936; O’Hara et al. 2013). Mortensen (1936) suggested that the number of segments at the base of the arm that only have one arm spine was a way of distinguishing South American (one segment) from South African specimens (5–6 segments). However, in our experience this result is not consistent across all specimens from these regions. The current specimens have one arm spine only for the first segment, however, despite having mature gonads they show no sign of bursal viviparity.
