 There are similarities in both the speed and duration of bouts of swimming, the style of movement and the posture adopted by the two.Typically, the plate fish swims for about 6 seconds (3-43s) and the octopus for 2 seconds (1–20s) and both then rest for 2 or 3 seconds (1–8s flounder, 1–13s octopus) before swimming again.Both keep close to the rippled sand contours of the seabed and the octopus keeps its eyes on the upper side of its body, which increases its resemblance to the lefteye flounder.
