The animal with the longest genitals is a certain species of cetacean - the sperm whale (Physeter macrocephalus). The length of the male sperm whale's genitals can reach 2.4-3.0 meters, which is longer than the length of the animal's body. The interior of their genitals contains a complex series of folds and embedded structures that may help control water flow and sperm transport during reproduction.
It should be noted that the length of the genitals does not represent the size or strength of the animal's body, but is just a special organ that has evolved in certain species.
