Biology

Studies conducted in 2010 at the University of Derby by Karim Vahed, Darren Parker and James Gilbert found that the tuberous bushcricket (Platycleis affinis) has the largest testicles in proportion to body mass of any animal recorded. They account for 14% of the insect's body mass and are thought to enable a fast re-mating rate.[3][4][5]
