I believe they do not have such a stomach like cows do. Since the majority of whales are carnivorous, not herbivorous, they only require one stomach with one chamber, not one with four chambers like ruminants do.
Well ruminants are animals with four-chambered stomachs, like cows or goats. WE are a ruminant. We have only one stomach, and we don't need to re-digest food. Like dogs and cats.
In their stomachs like we do.
Kangaroos, like cows, have chambered stomachs and will regurgitate their food to aid in digestion. Kangaroos are primarily grazers and receive most of their moisture from their food.
They have the same four-chambered stomach that cows have and are capable of chewing cud just like cows do.
Bison have four stomachs like all other bovines in the bovidae family.
Deer have a four-chambered stomach.
Oh, what a happy little question! Not all grass-eating animals have four stomachs, my friend. Animals like cows, sheep, and deer have four-chambered stomachs to help them digest tough plant material, but others like horses and rabbits have simpler stomach structures. Each animal is unique in its own special way, just like each brushstroke on a canvas.
There is no such animal on Earth at this time, that we know of. The animal with the most number of stomachs is the cow, which has a total of four.
Whales looks like fishes. They can swim in water like them but they are not fish as they respire with lugs, have four chambered heart, diaphragm, mammary gland, hairs, etc. Whales are viviparous like any other mammal.
A cow is like a goat because they are both ruminants, so are sheep and deer. That means that they all have four-chambered stomachs and are able to chew cud.
No, Goat stomachs are chambered and perform a different way than a human stomach. Like cows. They also produce gasses deadly to humans. Stomach transplants are very uncommon though and are usually done along with intestine, pancreas, or liver. With the low demand of stomachs there should be plenty in stock for someone who needs this rare transplant
No, though cows and whales come from a common ancestor being the Pakicetus. Cows are "sisters" to hippos, and both of these species are "cousins" to whales. Cows, like all other ungulates, have their evolution much farther back on the evolutionary tree than whales do. Whales came from mammals that went from being terrestrial to oceanic in a matter of 8 million years. See the related link below for more info.
