Overview
- A caretaker at Wroclaw Zoo filmed a standoff between Mundzak, a Chinese muntjac deer, and Maruska, a black rhinoceros, in their shared outdoor enclosure.
- The Instagram post from the zoo drew millions of views as the unusual encounter circulated widely on social media.
- Zookeepers said the behavior stemmed from excess testosterone because the deer's mate was in heat, characterizing the episode as a brief territorial display.
- The roughly 50-pound deer repeatedly charged the roughly 3,750-pound rhino, and the larger animal eventually retreated in the clip.
- A follow-up video shows the animals calmly eating hay together, and the zoo says the species have cohabited there for years with separate indoor areas.
