Dolphins also copulate throughout the year, largely to establish and maintain social bonds. In dolphins, the clitoris is positioned in the anterior aspect of the vaginal entrance, where physical contact and stimulation during copulation is likely. Clitoral stimulation seems to be important during female–female sexual interactions in common bottlenose dolphins (*Tursiops truncatus*), which rub each other’s clitorises using snouts, flippers, or flukes. Determining a sexual pleasure response in animals not amenable to neurobehavioral examination is difficult, but investigation of the clitoris may elucidate evidence of functionality. In this study, we assessed macro- and micromorphological features of the clitoris in common bottlenose dolphins to examine functional features, including erectile bodies with lacunae, extensible collagen and/or elastin fibers, and the presence and location of sensory nerves. Our observations suggest the clitoris of dolphins has well-developed erectile spaces, is highly sensitive to tactile stimulation, and is likely functional.
