We collected individual toads from the campus of James Cook University in Townsville, Queensland, Australia (-19.3329°S 146.7575oE) over five years and additional toads from locations in the Northern Territory, and Western and Southern Queensland and New South Wales in 2010 and 2011. Toads were captured by visual encounter and hand collection at night, or in traps. They were euthanised by an overdose of buffered MS222, and preserved by freezing before dissection. During dissection, we used Vernier callipers to measure body size (snout-urostyle length) and the length and width of any obvious (>5.5 mm growth) spinal abnormality (which typically presented as bulbous growths around the vertebrae) to the nearest 0.1 mm. We determined sex by direct examination of the gonads. Research was approved by James Cook University’s animal ethics committee (A1617) and all methods were performed in accordance with relevant guidelines and regulations.
