Yaş
The nilgai, also known as antilope albipes or blue bull, can live from 15 to 20 years, with a maximum lifespan of 21 years and 9 months, and a theoretical lifespan ranging from 10 years and 10 months to 21 years and 9 months. The species reaches sexual maturity between 2 and 4 years of age, and the young are born with their eyes open and begin walking immediately. During the embryonic stage, the fetus develops inside the mother, receiving nourishment via the placenta and not eating independently. The young then enters the infant stage, where it feeds on its mother’s milk for the first few months and hides in grass, rapidly growing and learning to run, with this stage lasting from 1 day to 6 months. The adult stage begins when the animal is capable of reproduction, lasting from 2 years to 20 years, during which males defend their territory and participate in mating contests.
Fenotip
The nilgau possesses a distinctive appearance that changes with age. A calf is covered in soft fur of light brown color with white spots on the sides, which serves for camouflage. The adult form has short fur of gray-blue color; however, in old males the coloration becomes darker and can also be reddish-brown or orange. An adult nilgau has straight conical horns with rings at the base, intended for protection and fights. Long, strong legs allow the species to run quickly and jump over obstacles. Also, an adult male has a short tail with a tuft at the end, which is used to scare away insects.
