Manatees are fed elephant vitamins in captivity, look at this.
'One of the changes for a manatee in captivity is their diet. Instead of feeding off of huge amounts of plant life, they are given a diet of mainly lettuce along with a few green plants. They are also given elephant vitamins. This is because in the wild a manatee will consume up to 9% of its body weight in food each day. They do so because there isn’t a high amount of nutrients in the foods they consume. In captivity these elephant pills help them to get full on less food. It also helps them to get all of the nutrients that they need without the same volume of food.' - Manatees in Captivity - Manatee Facts and Information
