Oral (lower) surface of the arm of a crown-of-thorns starfish (Acanthaster solaris) showing variation in the size (length and diameter) of tube feet along the length of the arm.

Fig 2.
Relationships for (a) average size of tube feet (mm), and (b) average number of tube feet per arm, with the total diameter of crown-of-thorns starfish (n = 42). Solid lines indicate the line of best fit and dashed lines indicate 95% confidence intervals.
Fig 3.
Relationships for a) mean velocity and b) maximum velocity with the total diameter of crown-of-thorns starfish (n = 42). Movement rates were quantified for three different substrate-types: paver (black circles), rubble (grey circles) and sand (white circles). Lines indicate the line of best fit for each different substrate type (paver: black line, rubble: grey line, sand: dashed line).
