The Etruscan shrew has a very fast heart beating rate, up to 1511 beats/min (25 beats/s) and a relatively large heart muscle mass, 1.2% of body weight. [3] The fur color on the back and sides is pale brown, but is light gray on the stomach. The fur becomes denser and thicker from fall through the winter. [8]
Like other ruminants, bovids have four-chambered stomachs, which allow them to digest plant material, such as grass, that cannot be used by many other animals. Ruminants (and some others like kangaroos , rabbits , and termites ) are able to use micro-organisms living in their guts to break down cellulose by fermentation .
The horns also make the animals a prized game trophy, which has led to the near-extinction of the two northern species. As an introduced species Between 1969 and 1977, the New Mexico Department of Game and Fish in the US intentionally released 95 gemsbok into its state's White Sands Missile Range [ 14 ] and that population is now estimated ...
The list of organisms by chromosome count describes ploidy or numbers of chromosomes in the cells of various plants, animals, protists, and other living organisms.This number, along with the visual appearance of the chromosome, is known as the karyotype, [1] [2] [3] and can be found by looking at the chromosomes through a microscope.
Colugos are shy, nocturnal, solitary animals found in the tropical forests of Southeast Asia. Consequently, very little is known about their behavior. They are herbivorous and eat leaves, shoots, flowers, sap, and fruit. They have well-developed stomachs and long intestines capable of extracting nutrients from leaves and other fibrous material.
(from Wiedersheim's Comparative Anatomy) Food digestion in the simple stomach of nonruminant animals versus ruminants [21] The primary difference between ruminants and nonruminants is that ruminants' stomachs have four compartments: rumen—primary site of microbial fermentation; reticulum; omasum—receives chewed cud, and absorbs volatile ...

The rumen, also known as a paunch, is the largest stomach compartment in ruminants. [1] The rumen and the reticulum make up the reticulorumen in ruminant animals. [2]The diverse microbial communities in the rumen allows it to serve as the primary site for microbial fermentation of ingested feed, which is often fiber-rich roughage typically indigestible by mammalian digestive systems.
