Which modern animal's niche is suggested as being similar to Arsinoitherium's specialized ecological role?

Answer

Modern Javan rhinoceros

The analysis ultimately leans toward classifying Arsinoitherium not as strictly semi-aquatic, but closer to a marsh-dweller or swamp-specialist. This niche is compared to that of the modern Javan rhinoceros. This comparison is apt because the Javan rhino is also a solitary browser found almost exclusively in dense, wet forests and swamps. While these animals may engage in wallowing in mud holes for cooling and protection from threats or heat, they are generally not classified as truly aquatic in their primary habits or physiology, mirroring the hypothesized state of Arsinoitherium.
