Leah Prudhomme of Minnesota sustained 25 bites from an otter during her 1.5-mile training swim in Island Lake. Luckily, the swimmer was wearing a wet suit which protected her from more extensive injuries. After the incident, Prudhomme was given rabies, tetanus and antibiotic shots and still plans on competing in a triathlon later this month on the same lake. Otter attacks on humans are rare with only 40 reported attacks in 20 years in the U.S., most occurring in Florida.
