Butterflies, birds and zebras: The magic of animal motion

The Royal Society of Biology has released the shortlist for its annual photography competition.

The competition has two categories for amateur photographers: four entries were shortlisted for young photographer of the year and six for the photographer of the year.

The shortlisted images showcase animals caught on camera around the globe, submitted according to this year's theme of Capturing Movement.

Image caption Sundhir Gaikward's entry in the photographer of the year category shows amphibious mudskippers engaged in territorial fighting. Mudskippers in particular are able to survive in air for several days. They breathe through the moist linings of their mouths and throats, so they prefer high humidity and are often found in muddy mangrove swamps.
