8. Reproductive Organs
8.1 Male reproductive organs
Male rabbits, known as bucks, have a unique reproductive organ called the scrotum. The scrotum houses the testicles, which produce sperm. Unlike humans, rabbits have testicles that descend into the scrotum only during breeding season or when they are sexually active. The size and prominence of the scrotum vary depending on the individual and can be a distinguishing feature among rabbit breeds.
8.2 Female reproductive organs
Female rabbits, referred to as does, possess a reproductive system that includes ovaries, fallopian tubes, and a uterus. The ovaries produce eggs, which are released into the fallopian tubes during the breeding cycle. If fertilization occurs, the eggs travel to the uterus, where they develop into embryos. Female rabbits do not have a menstrual cycle like humans; instead, they experience an estrous cycle, with varying receptivity to mating based on hormonal changes.
8.3 Sexual dimorphism
Sexual dimorphism refers to the physical differences between males and females of the same species. In rabbits, the most noticeable sexual dimorphism occurs in the region around the genitalia. Male rabbits typically have larger and more prominent genitalia, including a visible scrotum, while females have a smaller and less pronounced genital area. These differences aid in reproductive identification and contribute to the overall diversity and characteristics of different rabbit breeds.
9. Facial Features
