In this photo by Wong Maye-E, aquarists feed West Indian manatees at the River Safari wildlife park in Singapore. The river-themed park recently opened and has chosen the manatee as its animal icon. It has 14 West Indian manatees, a species that is considered vulnerable. Through captive breeding of manatees, the River Safari hopes to contribute to the species' population. To date, more than 10 manatees have been born in Singapore.
