Had a nice talk with the curator and the guy who manage and design exhibits today.
The giant otter just gave birth a day or two ago to at least 3 pups but none survived. The female seems to have problems raising her kids in the past. Still not much is known about these guys and maybe we'll get to see mini giant otters in the future.
Also, further renovations on this exhibit in works. Soon, the otters will have a bigger pool to swim around.
