Sexual dimorphism is quite subtle in Pharlans. Males and Females are similar in size and strength with males being slightly shorter and stockier with emales being taller and thinner. Sexual maturity is reached around 250 years of age while approximate full size is reached around thirty. Pharlans pair off at around 300 to 400 years of age. The young are hatched from relatively small eggs that are expandable and grow in size by absorbing solar radiation and energy from the parents. When a pharlan first hatches it is dependent on energy alone to sustain it. Within 24-36 hours it will be able to digest food and obtain energy from it but until that time the parents must consume large quantities of food to convert into energy for the hatchling.
