Combinations of body patterns, postural components, and papillae employed by locomoting Abdopus aculeatus

Body patterns and prominent skin componentsExample figuresProminent postural componentsPapillae patternsMode of locomotion
1. Ochre mottled (dorsal mantle white spots) 2D, 4C Mantle held horizontal to substrate away from body; arms sprawled around the body, coiled helically while walking Primary and supraocular papillae branched, flaplike Crawling, walking, multiarmed walking 
2. Dark mottled 4E, F Arms drawn near or under body, or curled at tips as while jetting Primary unbranched or slightly branched, supraoctular unbranched, secondary small, posterior lobate Crawling, walking, multiarmed walking, curled-armed jetting* 
3. Dark with pale medial stripe 4A,B,G,I-K Mantle typically held upright elongate, sometimes falls behind head; arms typically dragged straight below body, or sometimes tightly coiled Posterior lobate Crawling, walking,swimming*,jetting* 
4. Mantle gray, arms dark mottled 4D Arms curved backward, mantle conical Secondary Crawling with by using curved arms to push the body forward or to the side in jerky movements 
5. Uniformly dark 2C None consistent Secondary, none  
6. Uniformly pale 2A,B Elongate while jetting; head raised and dorsoventrally compressed while swimming None Crawling, swimming, jetting
