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]
After this, the digesta is moved to the true stomach, the abomasum. This is the gastric compartment of the ruminant stomach. The abomasum is the direct equivalent of the monogastric stomach, and digesta is digested here in much the same way. This compartment releases acids and enzymes that further digest the material passing through.
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 ...

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 sperm whale brain is the largest known of any modern or extinct animal, weighing on average about 7.8 kilograms (17 lb) [61] [62] (with the smallest known weighing 6.4 kilograms (14 lb) and the largest known weighing 9.2 kilograms (20 lb)), [44] [45] more than five times heavier than a human brain, and has a volume of about 8,000 cm 3.
