Briefly describe how these skulls are similar and different. ### Sexual Dimorphism in Gorilla SkullsGorillas exhibit significant **sexual dimorphism** in their skull features. This means that the skulls of male and female gorillas have distinct differences, which can be observed in certain anatomical features:- **Female Gorilla Skulls:** - **Smaller Size:** Female gorilla skulls are generally smaller compared to those of males. - **Sagittal Crest:** They have a very small sagittal crest, which is a ridge of bone running lengthwise along the midline of the top of the skull. - **Nuchal Crest:** The nuchal crest, located at the back of the skull, is small.- **Male Gorilla Skulls:** - **Larger Size:** Male gorilla skulls are larger than female skulls. - **Sagittal Crest:** Males possess a large sagittal crest, which is more pronounced than in females. - **Nuchal Crest:** The nuchal crest is also large, providing more area for the attachment of strong neck muscles.These variations in skull structure are essential for understanding the physical adaptations and behaviors of gorillas._Photo courtesy of SkullsUnlimited.com_

Gorillas are sexually dimorphic. They belong to the order primates. The average size of a male gorilla skull is 34cm long, 16cm high and 18cm wide. The male skull is more massive than the female skull. Female skull has a reduced nuchal crest and lacks a Sagittal crest. Sagittarius crest provide an extensive muscle attachment and is the bone ridge that is seen along the mid line on top of the skull. The canine teeth of female is smaller and ridge of the brow is pronounced less comparing to male skull. Male skull has prominent brow ridges.
