Speaking of large things in Seychelles, the coco de mer is the largest nut in the world and can grow up to weigh 30 kg. The trees have been recorded to grow to a height of 30 m in height. Due to an exploitation of the coconut, these nuts are almost extinct and require the need of a special license in order to be removed from the island. This rare type of palm tree is endemic to Seychelles and usually takes centre stage for various urban legends. One particularly interesting story stems from the fact that the fruits of the coco de mere; i.e. the nuts, resemble the buttocks of a female person while the male trees have a long catkin taking the shape of a phallus. As the pollination of the fruit is not clearly understood, legend has it that the male trees would approach the female trees and "make love" and that if anyone were to see this act, the individual would go blind or die.
