The conejo mexicano, or Mexican volcano rabbit (Romeralagus diazi), is a small, charismatic lagomorph endemic to the high-altitude volcanoes of central Mexico. It stands as a living relic, being the second-smallest rabbit species in the world and the only extant member of its genus, Romeralagus. Its restricted range and specialized habitat make it a vulnerable species facing significant conservation challenges.

Visually, the Mexican volcano rabbit is quite distinct. Averaging between 27 and 32 centimeters in length and weighing between 400 and 600 grams, it is noticeably smaller than the more common cottontail rabbits. Its short, dense fur is typically a dark brownish-black color, providing excellent camouflage within the volcanic grasslands it calls home. Unlike many other rabbits, the volcano rabbit lacks a visible tail. Its small, rounded ears further contribute to its unique, almost rodent-like appearance. These adaptations help it conserve heat in the frigid mountain environments.

The volcano rabbit is exclusively found in the zacatonal grasslands that grow at elevations between 2,800 and 4,250 meters on the slopes of volcanoes like Popocatépetl, Iztaccíhuatl, and Pelado. These grasslands are dominated by bunchgrasses, providing the rabbit with both food and shelter. They are primarily nocturnal and crepuscular, being most active during dawn and dusk. They live in small groups, typically consisting of two to five individuals, and use a network of tunnels and runways through the dense grass for protection and movement. Unlike many rabbit species, they do not dig their own burrows, instead relying on natural formations and the existing grass structure.

The diet of the volcano rabbit consists primarily of the zacatonal grasses that dominate its habitat. They are selective feeders, choosing the most nutritious parts of the plants. They also consume other herbaceous plants and occasionally the bark of small trees. Their specialized diet further limits their range and makes them susceptible to habitat degradation.

The species faces a multitude of threats, primarily related to human activities. Habitat loss due to agricultural expansion, livestock grazing, and deforestation is a major concern. These activities fragment the already limited habitat, isolating populations and reducing genetic diversity. Furthermore, hunting, both intentional and accidental (through trapping intended for other species), has contributed to population decline. Climate change also poses a significant threat, potentially altering the composition and distribution of the zacatonal grasslands. Increased temperatures and changes in precipitation patterns could negatively impact the species’ food source and overall habitat suitability.

Conservation efforts are underway to protect the Mexican volcano rabbit. These include habitat restoration projects, creation of protected areas, and community outreach programs. Educational initiatives are aimed at raising awareness about the species and the importance of preserving its habitat. Enforcement of hunting regulations is also crucial. However, the long-term survival of the conejo mexicano depends on continued and intensified conservation efforts, focusing on protecting and restoring its unique volcanic grassland habitat and addressing the underlying human pressures that threaten its existence.
