Fig. 7. Lift force on the body of a crab as a function of angle of attack. Values are means ± 1 S.D. of three replicate measurements at a velocity of 0.98ms-1 for one individual crab in the aquatic and the terrestrial posture. The actual values varied: the absolute value of the magnitude of the lift at angles of attack of +4° or -4° were greater for the aquatic posture than for the terrestrial posture, and lift acted upwards at angle of attack +4° but downwards at angle of attack -4°.
