1/23/2024 0 Comments Breeding of javan rhinocerosThe neck folds are less massive than in the greater one-horned rhino, but two folds continue over the back of the neck, forming a characteristic “saddle” on the neck-shoulder. As for the other Asian rhinos, there are two folds in the skin circling the body behind the front legs and before the hind legs, and horizontal folds at the base of the legs. Such prehensile lips are found in all browsing rhino species: the African black rhino, and the greater one-horned and Sumatran rhinos. Distinctive characteristics: Javan rhinos have long pointed upper lip, which assists in grasping their food.Senses: Javan rhinos have a good sense of smelling and hear very well, but are rather short-sighted.Over the years the teeth wear down by several centimetres to become shallow and dish-like, and making it difficult for older rhinos to break down their food The ridges of enamel on these teeth are used to cut up the woody parts of their food into characteristic 1-2 cm long pieces. Javan rhinos also have two rows of 6 strong, broad and low-crowned molars on each side. These are used in fighting and can inflict deep wounds. Teeth: like all Asian rhinos, Javan rhinos have long, sharp, dagger-shaped lower incisor teeth.It is not used for fighting, but for scraping mud from the sides of wallows, pulling down food plants, and for protection of the head and nose when breaking through dense vegetation Rhino horn has the same horn structure as the hooves of horses and re-grows if broken off. The longest horn ever recorded is only about 27 cm long and is now in the British Museum in London. Males have larger horns and many females, especially in Ujung Kulon, have no horn or just have a small knob on the nose. The horn: Javan rhinos have a single horn, grey or brownish in colour, usually less than 20 cm long.Skin colour: Javan rhinos have grey or grey-brown skin, almost black when wet, with pink colouring in the folds.Lifespan: Javan rhinos are estimated to live an average of 35 to 40 years in the wild.They typically range between 900 and 2,300 kg Weight: Javan rhinos are comparable in size to the African black rhino, though only a few animals have actually been weighed.There is not much difference in size between the males and females, and from information gathered in Ujung Kulon and from museum skeletons, there is a possibility that females are slightly bigger It stands at 1.4 to 1.7 metres tall at the shoulder.
