The first otters born at Perth Zoo, in Western Australia, in 18 years made their public debut on Sept. 17, 2012, during a health checkup by the zoo's veterinary staff.
The otter pups were born on June 19, 2012. Shown here, an 8-week old pup at Perth Zoo.
The pups are starting to become more active and adventurous, exploring their enclosure at the zoo.
The otters are native to freshwater streams, rivers, creeks and coastal regions in Indonesia, southern China, southern India, the Philippines and Southeast Asia.
At thirteen weeks old, the otters received a health checkup and vaccination.
Asian small-clawed otters are the smallest of the world's 13 otter species, typically weighing just under eight pounds (3.5 kilograms) when fully grown.
The species, which faces habitat loss in the wild, is listed as vulnerable on the IUCN Red List of Threatened Species.
