According to Pravda dolphins (or cetaceans is another term they use in the article but that may be a mistranslation?) have both a quick healing ability as well as the ability to sense electrical fields. For example, after being bitten by a shark, a chemical stored in a dolphin’s fat can heal it more quickly than land mammals similarly wounded. This is in part to the dolphin’s decreased risk of bacterial infection. The detection of electrical fields around fish help the dolphin find food and is accomplished through hairs found in small holes in its nose.
