...Min Tan; Jeremiah Y. O. Chan; Long Yu; Eunice J. Tan; Daiqin Li ABSTRACT Motion and camouflage were previously considered to be mutually exclusive, as sudden movements can be easily detected. Background matching, for instance, is a well-known, effective camouflage strategy where the colour...

... movements were of lower magnitude for all degrees of freedom examined (jaw protraction, yaw and pitch), and were bilaterally symmetrical with virtually no yaw. The magnitude of tongue protraction–retraction (Tx t ), relative to a mandibular coordinate system, was greater during mastication than during...

This thermally robust performance appears exceptional in light of the well-documented effects of temperature on muscle...

...Rebecca Wheatley; Christofer J. Clemente; Amanda C. Niehaus; Diana O. Fisher; Robbie S. Wilson ABSTRACT Movement speed can underpin an animal's probability of success in ecological tasks. Prey often use agility to outmanoeuvre predators; however, faster speeds increase inertia and reduce agility...

... efficiency of finding foothold by avoiding searching-movements in trailing legs. In stick insects, a ‘targeting mechanism’ has been described that guides foot-placement of hind- and middle legs according to the position of their leading ipsilateral leg. So far, this mechanism has been shown for standing...

To evaluate the potential anti-attachment effect of algal mats on sea urchins, a laboratory tank experiment was performed on the movement of Strongylocentrotus nudus sea urchins and their grazing on juvenile kelp plants at the center of 30×30 cm flat test...

In our experiment, an orienting response led to a sudden, rapid spin of the ball in the direction opposite to that of the stimulus. Because of their speed and discrete nature, orientation movements are easily...
