I photographed these bats during a nighttime wildlife expedition in Costa Rica. Seeing their delicate wing structure and all those tiny details up close was absolutely fascinating.

An extraordinary scene unfolded in False Bay when a whale began giving birth in the open water, attracting nearby sharks.Then hundreds of dolphins appeared and
they surrounded the mother whale and her newborn calf, swimming in tight circles and keeping the sharks at a distance. The pod stayed with them throughout the vulnerable birth, forming what appeared to be a protective barrier around the pair.
Once the mother and her calf were safely on their way, the dolphins remained alongside them, seemingly escorting them toward safer waters.
A remarkable display of what looked like protection, cooperation, and one of the most extraordinary encounters ever witnessed in False Bay.
