Manatee Facts
for Kids

Yes — manatees and elephants share a common ancestor and are classified together in the superorder Afrotheria. Their relationship is visible in details like nails on their flippers (similar to elephant toenails) and similar tooth replacement patterns. Manatees are not related to whales, dolphins, or walruses, despite their aquatic lifestyle.

The West Indian manatee (Trichechus manatus) is classified as Vulnerable on the IUCN Red List. Numbers declined severely in the 20th century due to hunting and habitat loss, partially recovering under legal protection. Red tide algal blooms — worsened by agricultural water pollution — have caused large mortality events in recent years, reversing some of that recovery.

Manatees are strict herbivores, eating seagrasses, algae, and freshwater aquatic plants depending on their habitat. A large adult can consume up to 50–60 kg (110–130 lb) of vegetation per day — roughly 10% of its body weight. They graze slowly along the bottom in shallow water, using their prehensile upper lip to grasp and pull plant material.

Manatees typically cruise at 3–5 km/h (2–3 mph), though they can sprint briefly at up to 25 km/h (15 mph). Their slow pace reflects low metabolic rates and a body shape built for efficient grazing, not speed. Their need to surface every 3–5 minutes to breathe, combined with slow movement in the same shallow coastal areas used by recreational boats, makes them extremely vulnerable to strikes.

Boat strikes are the leading cause of non-natural manatee death. Because manatees surface frequently to breathe and move slowly through shallow coastal waterways, collisions are common. Nearly every adult wild manatee in Florida carries propeller scars. Additional threats include red tide poisoning, cold stress syndrome in winter, habitat loss from coastal development, and entanglement in fishing gear.
