2 Min Read JOHANNESBURG (Reuters) - Being tall is the giraffe’s competitive advantage, giving it the pick of leaves from the tallest trees, so scientists were stunned to find two giraffe dwarves on different sides of Africa. “It’s fascinating what our researchers out in the field found,” Julian Fennessy, co-founder of the Giraffe Conservation Foundation, told Reuters in a videocall on Friday. “We were very surprised.” Most giraffes grow to 15 - 20 feet (4.5 - 6 metres), but in 2018, scientists working with the foundation discovered an 8 1/2-foot (2.6 metre) giraffe in Namibia. Three years earlier, they had also found a 9-foot 3-inch (2.8 metre) giraffe in a Ugandan wildlife park.
