Sharks are some of the oldest and, from an evolutionary perspective, some of the most successful marine vertebrates ever to have lived. They have spent their entire evolutionary history in the aquatic environment, and the body design in many species has been honed over hundreds of millions of years to increase swimming performance. Learn how body form, fins and even the skin, work in concert, enabling sharks to slice through water and execute complex maneuvers with startling speed and precision.

Ponds are one of many beautiful features of the Arnold Arboretum’s ecosystem and landscape. The Bradley Rosaceous Collection garden is the setting for three eco-rich ponds—Dawson, Faxon, and Rehder—named for former Arboretum staff. Photographer Bruce Wilson brings his now practiced eye to the discovery of shadows, reflections, visitor interaction, and flora in those ponds, as well as in an urban pond in Newton. His pond images complement the trees, emphasize the subtle or saturated colors of water, and capture interactions between visitors and the scenes of rich pondlife.
