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] The shrew usually has 30 teeth, but the 4th upper intermediate tooth is very small (rudimentary), and is absent in some individuals. [6]
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 2n=6 chromosome number is conserved in the entire family Culicidae, except in Chagasia bathana, which has 2n=8. [9] [9] 6 Indian muntjac (Muntiacus muntjak) 6/7: 2n = 6 for females and 7 for males. The lowest diploid chromosomal number in mammals. [10] [11] 7 Hieracium: 8: 8 Fruit fly (Drosophila melanogaster) 8: 6 autosomal and 2 allosomic ...
[6] The word "boodie" comes from its name boodi or burdi in Noongar, [7] [8] an Aboriginal language spoken in southwestern Australia. The animal was first collected on an 1817 French expedition of the west coast, and was named Bettongia lesueur after Charles Lesueur, an artist and naturalist who accompanied a previous French expedition.

Wildebeest have developed additional sophisticated cooperative behaviours, such as animals taking turns sleeping while others stand guard against a night attack by invading predators. Wildebeest migrations are closely followed by vultures , as wildebeest carcasses are an important source of food for these scavengers.
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.
