Since March, two escaped North American river otters (Lontra canadensis) have been leading the staff at the New Zoo Adventure Park in northeastern Wisconsin near Green Bay on an otterly wild chase. During a snowstorm on March 20th, security cameras showed otters Louie and Ophelia leaving their enclosures. The zoo staff believe they escaped through a hole in a buried part of the fence that had clearly gone unnoticed. Early in the morning on Thursday, March 20th, North American river otters Louie and Ophelia left their habitat. North American river otters are native to our area and are very comfortable and capable of surviving in Wisconsin’s climate,” the zoo reassured readers.
