The rhinoceros are animals with a singular aspect, which you will not easily confuse, large in size and with a thick gray skin covering them. There are five species of rhinos at this time, and three of them are at high risk of extinction. Their numbers continue to fall, because humans continue to destroy their environment and continue to hunt them down their horns.
A fully developed adult rhinoceros can weigh more than 1 ton. Their offspring weigh about 88 to 140 pounds at birth, rather large compared to the offspring of other animals.
