Half the population has them, and they've been the object of fascination for centuries—whether that be the physical organ itself or the phallus. You know what the Washington Monument is, right? Former Congressman Anthony Weiner was famously caught sending photos of his bare chest and erect penis and resigned for doing so this month.
Symmetry is usually prized as a sign of health and good genes, so why do so many organisms have lopsided genitalia? In them float the pickled remains of thousands of daddy-long-legs spiders waiting to be returned to natural history museums around the world. It was this tiny Venezuelan species that first put Huber, a world expert on daddy-long-legs spiders - not to be confused with crane flies or harvestmen - on the untrodden trail of the evolution of asymmetric genitalia.
It is often stated that the most negative argument against camel breeding is their slow and uncertain reproductive rate Novoa, In some areas camel breeding is even considered to be too hazardous to be undertaken systematically Gast et al. The camels are sexually mature at 4 to 5 years of age Evans and Powys, ; Mares, ; Yasin and Wahid,although a 3-year old camel can be used for reproduction Leonard, ; Novoa, ; Williamson and Payne,

Not only does it have fang-like canines, but the corner incisors and first premolars in the upper jaw along with the first premolars in the lower jaws have also been sculpted into fangs, all of which are readily put to use in the rutting season when it competes with other males for the services of a female. To parry the attacks, the males grow bushy beards under their chins.
