Each day, manatees eat around 120 pounds of food or about 10% of their body weight. Manatees’ favorite foods are different types of vegetation like seagrasses and mangrove leaves. They might ingest small fish or invertebrates occasionally, but mostly manatees stick to a vegetarian diet.
Manatees surface for air every three to five minutes and can stay submerged for up to 20 minutes while resting. Because they hang out in canals and shallow coastal areas, manatees often come in contact with boats. Colliding with motorboats is their biggest threat, along with other human-induced threats including fishhook ingestion and loss of habitat. You can help manatees by obeying local waterway rules and picking up your trash.
