Larger-than-life personalities
Eva
DOB: 13 Apr 1991
Eva is the largest manatee in Amazon Flooded Forest. She weighs about 1,200kg! The mother of eight calves and grandmother of seven, she is the grande dame of the herd.
Pedro
DOB: 27 Jul 1979
Pedro is the oldest male in our collection. To tell him apart from the rest, look out for his long, lanky frame. He often nibbles the aquarists, as a way of asking for food.
Canola
DOB: 6 Aug 2014
Canola was hand-raised by our aquarists when she was not observed to suckle. Every three hours in her first three months, Canola was bottle-fed a special mixture of puppy formula and goat milk, infused with canola oil, hence her name.

The manatees
High-fi and low-cal diet
Manatees spend 6-8 hours a day feeding on submerged and floating aquatic vegetation, which contain large amounts of roughage. Our manatees chomp on similarly high-fibre and low-calorie Chinese cabbage, banana leaves and elephant grass. They are known as sea cows because they spend half of the day grazing on sea grass and aquatic plants. They eat about 10% of their weight, which is between 350 and 600kg.
(In)digestion
It's not blubber that fills those barrel-shaped bodies, but an immense digestive system that includes up to 45 metres of intestines. Dedicated to digesting plant matter, this lengthy passageway extends digestion time and helps them absorb as much nutrients as possible. A single meal takes about a week to be fully digested!

Can you tell us how you train the manatees?
High-fibre pellets are our manatees’ favourite snack. These are given as rewards during operant conditioning sessions to get our manatees used to routine checks and medical procedures. Canola started training when she was two. She now responds to coloured targets and presents her flipper voluntarily for blood draws. She also cooperates for mouth swabs by lifting her head out of water and flips belly-up for ultrasound scans to detect and monitor any future pregnancies.

Please share with us any interesting incidents with the manatees.
On my first dive, one of the manatees – her name is Abel – came up to me and started to chew on my hair! They want to chew on anything. We use a long hose to clean the tank. The younger ones are very playful. They will come and give you a bump or play with the hose.

Do you know all the manatees by sight?
Yes, each one of them is different. I look at their size first, then their body shape and skin tone. Eva is the biggest, she’s 1,200 kilograms and 3.5 metres long. Pedro, one of the old males, is the leanest. Their faces and eyes are different. And so is the way they open their mouths - Eva likes to open her mouth wide above water during feeding.
Together, we protect wildlife
Abandoned calves
Whenever a baby is born, our aquarists keep a close watch for 48 hours to ensure it is suckling well. Sadly, scientists are seeing more orphaned calves in the wild. Separated from their mothers by human disturbance, these calves have been found stranded on coasts and left to fend for themselves.
