Volcano rabbit

The volcano rabbit (Romerolagus diazi) is a small species of rabbit that lives in pine and alder forests on several volcanic slopes in Mexico. It is the sole member of the genus Romerolagus and considered the most primitive species among the rabbits and hares. One of the smallest rabbits in the world, it has an adult weight ranging from 390 to 600 g (14 to 21 oz) and a total body length of 23 to 31 cm (9.1 to 12.2 in). Dense, short, yellowish brown fur covers its body, helping it to blend in with volcanic soil. It has short, rounded ears, and its short tail becomes hidden in adulthood. The volcano rabbit has a highly restricted habitat, being found only on the slopes of four volcanoes to the southeast of Mexico City. Human activities, including urban and agricultural expansion, have caused its habitat to become more fragmented, and hunting, livestock grazing, and fires threaten rabbit populations even inside protected areas.

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
