Definition
A 'sirenian mammal' is any member of the order Sirenia, including manatees and dugongs. These are aquatic, herbivorous mammals inhabiting warm, shallow waters. They are characterized by their slow-moving nature and reliance on seagrass for food. Sirenian mammals are distantly related to elephants. They face threats from habitat loss, boat strikes, and entanglement in fishing gear. They play an important role in maintaining seagrass ecosystems.
