"This photo was taken in Amboseli, Kenya. A group of hyenas were the aggressors in attempting to take on two female lionesses who they had sensed to be old or injured. The standoff lasted about 30 minutes, but in the end the hyenas were no match for the two lionesses who were able to get away unscathed."
"School of Munk's devil ray, pygmy devil ray, (Mobula munkiana), feeding on plankton at night, photographed on a long exposure."

"The open and arid landscape of Etosha NP is truly stunning. The goal of my trip was to photograph zebras with their striking coats across this backdrop. A herd of zebras arrived at the waterhole to quench their thirst. Suddenly, there was chaos and thick dust clouds blinded our vision. Within moments, two male zebras emerged from the dust, landing blows at each other with their hooves and heads. The duel lasted only a few minutes but it gave me an opportunity to capture this heavily charged moment."
