25. In sea lions, which swim with their forelimbs, the longest finger is 1.7
times as long as the first part of the limb (the humerus). In seals, which swim
with their hind limb, the longest toe/femur ratio is 2.4. In Ambulocetus, this
ratio is 1.1, and in the protocetids Rodhocetus and Maiacetus it is 0.95 and
0.79, respectively. The small foot of the protocetids suggests that it is less
involved in propulsion than that of ambulocetids.
