The coelacanth does indeed move its four limb-like fins in an
alternating fashion just as landlubber tetrapods do, with the
right front fin working in synchrony with the left rear fin
and the left front with the right rear. (Picture a dog
walking.) But instead of walking along the seabed, the fish
glides through the water like a slow bird, and can swim
forward, backward, and belly up. Coelacanths have even been
seen periodically performing headstands for up to two minutes
at a time.
