Landlocked Walrus
The Landlocked Walrus is a creature from Lumberjack Folklore in Maine. It has the “scientific name” Odobenus rosmarus var. chesuncookia. It’s described as smaller than the oceanic walrus and lives in freshwater in the region of Chesuncook Lake. It’s thought they became trapped in this area during the ice age. They are typically thought to be more dangerous than the typical walrus due to having less marine territory. They have been known to attack people and capsize boats with their tusks, or break through the ice to attack those walking on it. They are rare and not often seen, with them being seen as likely extinct now.
