The last month has seen a dramatic influx of new material, with a particular emphasis on marine life, reptiles, birds and invertebrates. Additions of note include sharks from David Fleetham, Galapagos giant tortoises and marine iguanas from Tui de Roy, Alex Hyde's material from the remote Manu National Park in Peru, Bruno D'Amicis coverage on the ancient beechwoods of Abruzzo, David Tipling's bird behaviour images and more amazing marine creatures from Alex Mustard.
