The last month has seen a bumper crop of new images on our site. Some of the many highlights include whales, dolphins and porpoises from British waters and Baja California, rare images of platypus, shark courtship and nurseries, Galapagos seabirds, Spring migrant birds and wildflowers, Cuban crocodiles and Tsavo's amazing tuskers, not to mention some dramatic coverage of catfish hunting pigeons and some very appealing emperor penguins!
