Porcupines No, it's not the prickly issue of spines getting in the way, more the porcupine penchant for golden showers that makes their mating ritual a little odd. Firstly, the male begins by following his selected partner around, carefully sniffing every spot in which she urinates. Then, once the pair are comfortable, and the female has obligingly reared up belly-to-belly with her mate, he then proceeds to urinate all over her. If she accepts, they then go on to mate until the male is worn out. If she doesn't accept, the male is forced to try again meaning the weird urine-based courtship can go on for up to six months. Red-sided garter snakes The small and highly poisonous snakes are big fans of group sex and, it seems, not necessarily that fussed if their partner is even alive. Up to 25,000 snakes slither into a large den, with some females having up to 100 males attempting to mate with her at a time. They then form 2ft 'nesting balls', which has the unfortunate consequence of crushing some of the poor females to death. The males however do not take this as a sign to stop and, overtaken by lust, continue to mate with her cold dead corpse. Now that is weird. Bed Bugs The bed bug mating ritual is a bit like a dodgy B-movie horror script. The male engages in a process called 'traumatic insemination', which is just as gruesome as it sounds. Rather than go through the process of wooing a mate and a long-winded relationship, the male bed bug simply stabs a hole in the female's abdomen before inseminating her, hence the moniker 'traumatic'. Lynx Spiders The way to a Lynx Spider's heart is through their stomach. The male spins a web, which captures his beauty, before spinning silk around her. The web is actually a wonderful aphrodisiac for the female Lynx Spider, who happily tucks into her silken bonds. Meanwhile, the male spider gets into position and then mates with his partner while she is distracted with her slap-up dinner. The male Uganda kob When mating season arrives for the male Uganda kob, one lucky male is in for a very tiring time. After each male has set up a mating territory, or lek, all of the females select a single male, and proceed to mate with him. Eventually the male is too weak to continue (usually due to lack of food and a distinct lack of recovery time) and the females move on to another mate.
