The truly amazing Javan Rhino quite easily ranks as the fourth rarest creature on earth. There are none currently in captivity and only 40 known left in the wild. Unfortunately, it is 1 of only 5 species of rhino left surviving and is likely to be extinct soon.
They also grow to an amazing average of 10.5 feet (3.2 m) in length and 5.8 feet (1.7 m) in height at the shoulder and can weigh as much as 5000 pounds (2300 kg). Further, only the adult males possess the horns, while females lack them entirely. This represents a significant degree of the principle of sexual dimorphism.
The Javan Rhino is the rarest of all large mammals on earth. In fact, all known survivors of the species currently reside in Ujong Kulon National Park on the island of Java, located in Indonesia.
Javan Rhino Behavior
Historically, this remarkable animal’s habitat mostly included wet grasslands, rainforest, and large floodplains. Now, unfortunately, they currently reside only within one small area.
The Javan Rhino live as primarily solitary creatures, except for the breeding and rearing of the young. Within their entire endemic range, they have no natural predators.
The large mammal is entirely herbivorous. They generally feed by using their long powerful bodies to dislodge twigs, leaves, and fruit from small trees, sometimes felling the trees entirely. They then use their ultra-capable of grasping upper lip to grab the food. An adult of this impressive species consumes an amazing average of 110 pounds (50 kg) of food per day!
The animal is also under protection, but the IUCN still lists it as “Critically Endangered”. Their numbers are now far too few to prevent eventual extinction from genetic instabilities incurred through inbreeding.
