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

Body patterns and prominent skin components	Example figures	Prominent postural components	Papillae patterns	Mode 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
