Rhino is a creature type.
There are basically two kinds of Rhinos in Magic. The basic earth-like rhino on the one hand and the Rhox-type rhino on the other.
Earth-like rhinos These guys are merciless bulldozers. Once one is charging at you you are basically already lost. Most of these have trample or some other ability that makes blocking hard. The message is clear. Stay out of their way.
Rhox-type rhinos These creatures are antropomorphic rhinos. They are close in flavor to Loxodon but with some small differences. The first of this category was Rhox from Nemesis. It was popular due to regeneration and it got a small following.
The Rhoxes share two qualities with the Loxodon. A love for battle and a love for spirituality. However, Rhoxes seem more aggressive in battle, acting akin to their animalistic counterparts. They are more in touch with their green side. However, the white Rhoxes are more serene in their stance. Lots of white Rhoxes still believe that might makes right but not all are killing machines. Most strive towards balance. But the thing that sets them apart the most from the Loxodon is that they never avoid confrontation but actively seek it.
