Greater Guinea Pig
cavia magna
The Greater Guinea Pig (Cavia magna) is a surprisingly large wild relative of the common domestic guinea pig, native to the wet coastal regions of South America. Unlike its dry-land cousins, this robust rodent has adapted to a semi-aquatic lifestyle, making its home in marshes, swamps, and wet grasslands. It is highly social and active, navigating dense wetland vegetation with surprising agility.
生息地: Typically found in freshwater marshes, wet grasslands, and swampy areas with dense vegetative cover.
外見
The Greater Guinea Pig is a stout, tailless rodent, noticeably larger than other wild cavies, with a body length of up to 40 centimeters. It features a coarse, dense coat of dark agouti fur, blending brown and black tones that provide excellent camouflage in muddy marsh environments. It has a blunt snout, small ears, and strong, dark-clawed feet designed to traverse wet, slippery substrates.

おもしろい事実
Because they live in nutrient-dense wetland ecosystems, their diet consists of water-rich plants, meaning they rarely need to drink freestanding water.
Greater Guinea Pigs are highly skilled swimmers, a trait which sets them far apart from domestic guinea pigs that fear water.
To avoid being seen by aerial predators, they maintain very specific, covered runways underneath the dense marsh reeds.
