This is an X-ray projection of a brown long-eared bat. Generally hunted and killed by domestic cats, these bats have relatively large ears and are common in the UK and across Europe. They are nocturnal, sleeping during the day in roosts, and hibernate from October/November to March/April.
Created by Chris Thorn, this X-ray of a bat was one of the 18 winning images in the Wellcome Image Awards 2014. Celebrating the best in science imaging talent and techniques, the Wellcome Image Awards are now in its 13th year.
The X-ray image was made using minimal kV exposure (low-energy X-rays) with a micro-focus system (to produce a high-resolution image). Exposure parameters were deliberately controlled to allow the complete natural form to be imaged, and to suppress invasive examination of the torso and cranial region. The choice of photo paper and processing chemistry were selected to emphasise these characteristics.
