The Javan rhinoceros, commonly known as the lesser-one-horned rhino, presents quite the ecological conundrum. Historically native to Southeast Asia, their modern populace is resigned to the confines of Java's Ujung Kulon Nature Reserve.

Critically endangered, the rhino population is at an estimated 683, with only a third considered reproductive. This decline links directly to the rising demand for their horn for traditional medicine.

Another contributing factor is habitat loss, led by human encroachment. Equally damaging is the proliferation of the local langkap palm, stifling the growth of the rhino's food plants.

Javan rhino sports the smallest horn of its genus, a mere 10-inch protrusion in males, while females do not have them at all. Its distinct grey hide is characterized by sectional creases stemming from rigid folds.

Primarily a herbivore, Javan Rhinos do not eat grass but prefer softer vegetation, preferring figs and guest-tree plants.
