Scores for feeding mode, movement type, speed and duration during day for each species.

The activity quotient is derived as the fourth root of the product of the feeding and activity scores (based on [16]). In feeding mode:1 = passive ciliary, 2 = pumping, 3 = grazing, 4 = capture. In movement type:1 = sedentary, 2 = sedentary + muscular activity, 3 = crawling, 4 = burrowing, 5 = walking, 6 = swimming. In movement speed:1 = none, 2 = slow, 3 = medium, 4 = fast. In movement duration:1 = never, 2 = very rare, 3 = occasional, 4 = sometimes, 5 = often.
