Body patterns and prominent skin componentsExample figuresProminent postural componentsPapillae patternsMode of locomotion
1. Ochre mottled (dorsal mantle white spots)2D, 4CMantle held horizontal to substrate away from body; arms sprawled around the body, coiled helically while walkingPrimary and supraocular papillae branched, flaplikeCrawling, walking, multiarmed walking
2. Dark mottled4E, FArms drawn near or under body, or curled at tips as while jettingPrimary unbranched or slightly branched, supraoctular unbranched, secondary small, posterior lobateCrawling, walking, multiarmed walking, curled-armed jetting*
3. Dark with pale medial stripe4A,B,G,I-KMantle typically held upright elongate, sometimes falls behind head; arms typically dragged straight below body, or sometimes tightly coiledPosterior lobateCrawling, walking, swimming*, jetting*
