There are technically two distinct species, the short- and long-finned pilot whale; however, it is nearly impossible to tell the two species apart while at sea. Typically, the short-finned are found in tropical and sub-tropical waters while the long-finned inhabit the colder regions, particularly the Southern Ocean. Wherever you may encounter these dark colored, large dolphins, you will be sure to leave with a million memories. Diving with these whale species is a rare yet exhilarating experience. If you are lucky enough to come across these beautiful mammals it is sure to be one of the most exciting encounters you could ever have since they live in very large pods of up to 100 individuals.
