A monogastric organism has a simple single-chambered stomach (one stomach). Examples of monogastric omnivores include humans, pigs, hamsters and rats. Furthermore, there are monogastric carnivores such as cats. [1] A monogastric organism is contrasted with ruminant organisms (which have four-chambered complex stomachs), such as cattle, goats ...
(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 Etruscan shrew has a very fast heart beating rate, up to 1,511 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]
The largest animal currently alive is the blue whale. The maximum recorded weight was 190 tonnes (209 US tons) for a specimen measuring 27.6 metres (91 ft), whereas longer ones, up to 33 metres (108 ft), have been recorded but not weighed. [1] [2] [3] It is estimated that this individual could have a mass of 250 tonnes or more.
More than 99 percent of all species, amounting to over five billion species, [7] that ever lived on Earth are estimated to be extinct. [8] [9] Estimates on the number of Earth's current species range from 10 million to 14 million, [10] of which about 1.2 million have been documented and over 86 percent have not yet been described.

The earliest bovids, whose presence in Africa and Eurasia in the latter part of early Miocene (20 Mya) has been ascertained, were small animals, somewhat similar to modern gazelles, and probably lived in woodland environments. [16] Eotragus, the earliest known bovid, weighed 18 kg (40 lb) and was nearly the same in size as the Thomson's gazelle ...

It is a generalist animal—it can adapt to a variety of habitats. [2] Though sedentary and less dependent on water, nilgai may desert their territories if all water sources in and around it dry up. [43] Territories in Texas are 0.6 to 8.1 square kilometres (0.23 to 3.13 sq mi) large. [2] The Indian population was estimated at one million in ...
