Volcano Rabbit (Romerolagus diazi) lives in alpine meadows across Mexico mountains. It feeds on grasses and leaves. Its conservation status is Endangered.
Fascinating facts about the Volcano Rabbit
- Weighing just 386-602 g and measuring 23.4-31.1 cm long, the volcano rabbit is with ears under 4 cm that barely stick out. Such miniature dimensions make it one of the world's tiniest leporids. Yet only about 7,000 adults survive across its whole range.
- Grass isn't just cover, it's the rabbit's pantry. One study found Muhlenbergia macroura in 89 % of its pellets, making this tussock the staple of its diet. Because that single grass can't meet all protein needs, the rabbit supplements with flowers, seeds, roots and bulbs. Food limitation, therefore, is a key driver of how many rabbits a patch of volcano can sustain.
- The rabbit lives on a patch of land no bigger than a midsized city, just 386 km² of volcanic slopes, at elevations from 2,800 m up to 4,250 m. This razor-thin strip of alpine scrub is all the species has left.
- Unlike any other rabbit, the volcano rabbit lets out a sharp, high-pitched bark to warn its group of danger, a vocal habit it shares only with distant pikas. This alarm call lets members of a 2-to-5-animal family know when a predator is near.
- Predators keep the volcano rabbit on edge: in the Iztaccíhuatl-Popocatépetl National Park it accounts for 12.5 % of bobcat kills and 5.5 % of coyote kills.

About the Volcano Rabbit
In the shadow of Mexico's volcanic peaks, the volcano rabbit navigates a fragile landscape of twisted pines and rocky outcrops, its large brown eyes watchful for predators as it darts through the underbrush with an air of quiet urgency. With a soft, grey-brown coat that blends seamlessly into the surroundings, this elusive creature moves unseen, its gentle paws barely disturbing the forest floor as it searches for the tender shoots and leaves that sustain it. As one of the most endangered rabbits in the world, the volcano rabbit's very existence is a testament to the resilience of life in the most unforgiving of environments.
