Facts about Manatees
- 09
Flippers on these aquatic mammals each end in three to four vestigial nails, remnants of toes inherited from a land-dwelling ancestor shared with elephants roughly 60 million years ago.
- 08
Christopher Columbus's crew may have been among the first Europeans to encounter manatees in 1493, with sailors possibly mistaking them for mermaids due to their aquatic nature and rounded heads.
- 07
Manatees possess around 40 teeth distributed across their jaws, with molars constantly migrating forward as older teeth wear down and shed throughout their 60-year lifespan.
- 06
Scars on manatee bodies create unique identification patterns that researchers use to track individual animals, with photo-identification studies documenting the same manatees over decades.
- 05
Each manatee consumes approximately 10-15 percent of its body weight daily in aquatic vegetation, requiring 7-8 hours of grazing per day to meet its nutritional needs.
- 04
Manatees require water temperatures above 68 degrees Fahrenheit to survive, causing thousands to congregate at Florida's warm-water power plants during winter months.
- 03
Holding their breath for up to 20 minutes, manatees can dive to depths of 36 feet while foraging for seagrass on the ocean floor.
- 02
A manatee's teeth continuously replace themselves throughout its lifetime, with new molars moving forward in the jaw to replace worn ones, similar to a conveyor belt system.
- 01
Between 6,000 and 8,000 manatees inhabit Florida waters today, down from an estimated 200,000 before human settlement.
