Fourth year veterinary students from the University of Sydney's Faculty of Veterinary Science have produced a nude calendar in which they use a variety of strategically placed animals to protect their modesty.

The calendar, called Under the Overalls, features a variety of animals, including three lucky (depending on your point of view) llamas, a calf, three sheep and a rather unfortunate fish.

It's all in aid of charity. For more information, visit https://www.facebook.com/undertheoveralls, or you can buy the calendar for $20 at www.undertheoveralls.com.
