FIVE giant fresh water sting rays were delivered to the Singapore Zoo today, for an upcoming attraction called, The River Safari to open in 2012.

While the sting rays received today were only about 10 kilos in weight and 40 centimeters across, they do grow to astonishing sizes, weighing up to 500 kg and 5 meters in length.

The 5 sting rays, each about 2 years old, originate from the Chao Praya river in Thailand.

Sting rays are generally gentle creatures. However, they shot to infamy when TV personality Steve Irwin died in a freak accident after being pierced in the chest by a sting ray barb.
