Rhinos are generally solitary, but can occur in small, matriarchal-organized herds.  Bulls are mostly loners and live territorial. The individual animals live in tightly defined areas that are marked with urine and feces.  Rhinos are more active during dusk and at night then they are during the daytime.  They are shy animals that avoid human contact, so reports of rhino aggressiveness are usually greatly exaggerated.  The Asian rhino species, which all have a front dentition, use their horns rarely in battle except with other rhinos; their real weapons are the dagger-like incisors of the lower jaw, with which they tear dangerous and deep wounds. The African rhino species will use their horns as a primary weapon for defense or themselves or territory against other animal species.

After a gestation period of 15 to 18 months, a calf is born, and stays with the mother for two and a half to three years. If a second calf is born during this time the older one is chased away by the mother.  The life expectancy is between 30 to a maximum of 50 years.  Age determination of fossil species has been made by a comparison to the white rhinoceros and is based on anatomical features such as tooth eruption, degree of use of individual teeth or adhesion stages of certain bone sutures. In general, mammalian life expectancy is closely related to adult body weight and extinct rhinos, which are similar in size to those of today, are likely to be in an equivalent range.
