How much does a Spix’s yellow-toothed cavy weight?

It is hard to guess what a Spix’s yellow-toothed cavy weights. But we have the answer:

An adult Spix’s yellow-toothed cavy (Galea spixii) on average weights 361 grams (0.8 lbs).

The Spix’s yellow-toothed cavy is from the family Caviidae (genus: Galea). It is usually born with about 33 grams (0.07 lbs). They can live for up to 4.58 years. When reaching adult age, they grow up to 12 cm (0′ 5″). On average, Spix’s yellow-toothed cavys can have babies 6 times per year with a litter size of 2.

As a reference: An average human weights in at 62 kg (137 lbs) and reaches an average size of 1.65m (5′ 5″). Humans spend 280 days (40 weeks) in the womb of their mother and reach around 75 years of age.

Spix’s yellow-toothed cavy (Galea spixii) is a rodent, a cavy species from South America. It is found in Bolivia east of the Andes and much of south central to northeastern Brazil. The species is found in open savanna and semiarid habitats, such as the Cerrado and Caatinga of Brazil. Its karyotype is 2n = 64 and FN = 118.Galea spixii and G. musteloides are similar and may actually be the same species. G. spixii tolerates a wide range of environmental changes, though they need open habitats. It is the most stable species within the Galea group because it is extremely abundant throughout its range.Gestation is about fifty days. Litters size ranges from one to five, with an average of three. They have hair and open eyes at birth. Maturation of the two sexes takes differently long: female G. spixii have an open vagina when they are approximately eighty days old while the testicular descent is completed in male G. spixii at around one hundred thirty-five days old. Males and females in this species are aggressive to each other. Paternal care is rarely remarkable. When females go into estrus aggressiveness increases. On the other hand, when male approaches females in order to mate, it competes aggressively with other males. A study done in Brazil reported that nine male cavies were put to death to experiment their sperm recovery by soaking or injecting their sperm into a liquid that contained a chemical buffer. Unfortunately, there were no distinctive results between either soaking or injecting.
