Description
TABLE 1. Description of measurements (in mm) and counts. Definitions largely follow Roper and Voss (1983). Indices (abbreviations shown in square brackets below) are calculated by expressing each measure as a percentage of mantle length.
| AL | Arm Length. Arm measured from first basal (proximal-most) sucker to distal tip of arm. |
|---|---|
| AL1 | Length of Arm 1. Same abbreviation for arms 2, 3 and 4. [AL1I—AL 4I] |
| Dorsal arm | Alternate term for arm 1. |
| Dorso-lateral arm | Alternate term for arm 2. |
| AL4l | Arm Length left hectocotylus in males. [AL4lI] |
| AL4r | Arm Length right hectocotylus. Length of right hectocotylised arm in males. [AL4rI] |
| ASC | Arm Sucker Count. Total number of suckers on each designated arm (e.g. ASC 2). |
| ASC 4l | Arm Sucker Count hectocotylus. Number of suckers on proximal end of hectocotylised left ventral arm. |
| ASC 4r | Arm Sucker Count hectocotylus. Number of suckers on proximal end of hectocotylised right ventral arm. |
| AS | Arm Sucker diameter. Diameter of largest normal sucker on each designated (i.e. 1, 2 etc.) arm. [ASIn]. |
| ClL | Club Length. Length of tentacular club measured from proximal-most basal suckers to distal tip of club. [ClLI] |
| ClRC | Club Row Count. Number of suckers in transverse rows on tentacular club. |
| ClS | Club Sucker diameter. Diameter of largest sucker on tentacular club. [ClSI] |
| EgD | Egg Diameter. Diameter of largest egg present in the ovary or oviduct. [EgDI] |
| ED | Eye Diameter. Diameter of eye. [EDI] |
| FIa | Fin Insertion anterior. Anterior origin of fin measured from mantle margin to anterior-most junction of fin and mantle. [FIaI] |
| FL | Fin Length. Maximum length of single fin. [FLI] |
| FW | Fin Width. Greatest width of single fin. [FWI] |
| FFu | Free Funnel length. Length of the funnel from the anterior funnel opening to the point of its dorsal attachment to the head. [FFuI] |
| FuL | Funnel Length. Length of the funnel from the anterior funnel opening to the posterior margin measured along the ventral midline. [FuLI] |
| GiLC | Gill Lamellae Count. Number of lamellae on one side of each demibranch (excluding the terminal lamella). |
| GilL | Gill Length. Length of the gill measured from terminal lamella to origin of gill. [GilLI] |
| HL | Head Length. Dorsal length of head measured from point of fusion of dorsal arms to posterior end of head. [HLI] |
| HW | Head Width. Greatest width of head at level of eyes. [HWI] |
| ML | Mantle Length. Dorsal mantle length. Measured from anterior-most point of mantle to posterior apex of mantle. |
| MW | Mantle Width. Greatest width of mantle. [MWI] |
| VML | Ventral Mantle Length. Length of ventral mantle measured along ventral midline. [VMLI] |
