As a marine life artist, one of my favorite subjects is the gentle giant, the manatee. In my manatee art paintings, I try to capture an accurate depiction of this mammal. You can view my manatee art here at bluewaterart.org or see my posts on Facebook. Please like me on Facebook and share with your friends. There you will see other sea life art in progress including dolphin art paintings, shark paintings and other endangered sea life art paintings. Back to the gentle giant and a few fun facts – Manatees spend approximately 50% of the day sleeping submerged and surfacing for air regularly at intervals of less than 20 minutes. Manatees swim about 3.5 mph; they have been known to swim up to 20 mph in short bursts. Manatees are herbivores and eat over 60 different fresh and salt water plants and eat up to 10 to 15% of their body weight.
