Figure 15 in Recognising variability in the shells of argonauts (Cephalopoda: Argonautidae): the key to resolving the taxonomy of the family
Figure 15. Argonauta nouryi shell displaying three changes in shell formation type: a–b, two perspectives of shell #41 (64.7 mm shell length, SBMNH 345766) displaying three changes in shell formation type from Type 1 (T1) to Type 2 (T2) shell formation, back to Type 1 and then to Type 2; a, left lateral view; b, oblique left lateral view. Note that the key to recognising the different shell formation types (challenging in this shell) is to look for reductions in the size of sequential keel tubercles (that would normally increase in size), a change in the relative distance between keel tubercles, a change in the ratio of lateral ribs to keel tubercles, and the appearance or disappearance of inter-keel tuberculation. Scale bar = 1 cm.

The shell added to the aperture edge in Type 1 shell formation produces a new ear separate from the axis of the shell. The new ear becomes the widest point on the aperture edge. Scale bars = 1 cm.

The shell added to the aperture edge in Type 2 shell formation does not expand the ear, instead subsuming it. The resulting aperture edge is not eared. Scale bars = 1 cm.

Figure 6 in The identity of juvenile Polynoidae (Annelida) in the Southern Ocean revealed by DNA taxonomy, with notes on the status of Herdmanella gracilis Ehlers sensu Augener
Figure 6. Haplotype network of 20 haplotypes based on Austrolaenilla antarctica and Herdmanella gracilis mtCO1 data: a, representing 91% connection limit; b, representing 95% limit. Small black circles represent unsampled haplotypes, large circles represent the sampled haplotypes with their size proportional to the frequency of the haplotype (n = 1, 2 and 7). Numbers in the shapes correspond to haplotype identification numbers (see table 2). Different geographical locations are coded—white circles are Amundsen Sea BIO4, 500-m depth; light grey circles are BIO4, 1500-m depth; dark grey circles are BIO3; cross-hatched circles are Weddell Sea; horizontal hatched circles are Elephant Island; and black circles are South Georgia.
