From sex-changing fish to rodents that mate themselves to death, a look at some of the odder ways animals pass on their genes.

Including bees that carry out a stealthy hive coup, giraffes making use of their dense skulls, and the jaws of the fearsome Tasmanian devil.

Animal parallels with our behaviour include faithful pigeon husbands, dolphin gangsters, and bees in trouble for getting drunk on the job.
