'Galumphing' is a method of locomation employed by
earless seals. Earless seals cannot turn their hind flippers downward, and as such they appear to be very clumsy on land, having to wriggle with their front flippers and abdominal muscles. The result is an almost comical method of movement, that is not intended to be used over long distances.
A smiliar mode of movement might have been employed by
Hesperornithes, namely the
genus ''
Hesperornis''. These were prehistoric
flightless birds specialized for swimming and diving. Their lower legs were flush with and probably even attached to the sides of the body, and the feet stretched away sideways. This made them excellent divers, but almost certainly completely unable to walk. Consequently, they either had to galumph, or to slide along on their bellies like
otters do. Other Hesperornithes, such as the smaller ''
Baptornis'' might have been able to manage short hops with their feet.
