The animal often referred to as a "sea cow" is the manatee. Manatees are large, gentle marine mammals known for their slow and graceful movements. They inhabit warm coastal waters, rivers, and estuaries, primarily feeding on seagrass and aquatic vegetation. These herbivorous creatures play a crucial role in maintaining healthy ecosystems by grazing on plants, promoting growth and nutrient cycling. Manatees are often threatened by habitat loss, boat strikes, and entanglement in fishing gear. Conservation efforts aim to protect their habitats and raise awareness about these peaceful creatures, as they are an important part of marine biodiversity.
