'Touching Trust' by Thomas P Peschak, from Germany/South Africa. Highly Commended in the Wildlife Photojournalism category. This shot, which was Highly Commended, shows a curious young grey whale approaching a pair of hands reaching down from a tourist boat. In San Ignacio Lagoon, on the coast of Mexico’s Baja California, baby grey whales and their mothers actively seek contact with people for a head scratch or back rub.
