Scientists have discovered a new mating position named the dorsal straddle that appears to only be used by the Bombay night frog, The Guardian reports. Previously, six mating positions had been observed in more than 6000 frog species. In the journal PeerJ, researchers describe observing males straddling females, but unlike other species the male never clasps the female and instead grasps leaves and vegetation around the pair. Additionally, unlike other frogs, the male releases his sperm before the female lays her eggs. The team has a video here.
