The Eurasian Otter (Lutra lutra): A Scientific, Ecological, and Conservation Overview The Eurasian Otter is a semi-aquatic mammal widely distributed across Europe, Asia, and parts of North Africa.  As an apex or mesopredator in freshwater and coastal ecosystems, it plays a crucial role in maintaining ecological balance.  This article synthesizes current scientific knowledge on its taxonomy, morphology, distribution, habitat use, behavior, diet, reproduction, population dynamics, and conservation status.  Emphasis is placed on ecological function, environmental indicators, and recovery efforts following historical population declines. 1.
