Lyell (remember him?) gave the following explanation for the presence of the hippototamus in Europe:
"The geologist may freely speculate on the time when herds of hippopotami issued from North African rivers, such as the Nile, and swam northward in summer along the coasts of the Mediteranean, or even occasionally visited islands near the shore. Here and there they may have landed to graze or browse, tarrying awhile, and afterwards continuing their course northward. Others may have swum in a few summer days from rivers in the south of Spain or France to the Somme, Thames, or Severn, making timely retreat to the south before snow and ice set in."

:’D Yeah, because hippos are known to prefer floating in open seas aboard slippery logs. Geez. :’D
