The animal with the most stomachs is the Bairds beaked whale, which can have more than 13 stomachs. The whale has two large stomach chambers, its main stomach and a pyloric stomach, and a series of connecting chambers between stomachs. Other animals with multiple stomachs include:

• Cows, which have four stomach compartments: the rumen, reticulum, omasum, and abomasum.
• Sheep and goats, which also have four stomach compartments.
• Deer, which have three stomachs.
• Giraffes, which have four stomach compartments.
• Kangaroos, which have four stomach compartments.
• Elk, which have four stomach compartments.
• Camels, which have three stomach compartments.

These animals have developed specialized digestive systems to efficiently break down and extract nutrients from their food. Each stomach compartment has a specific function in the digestion process, and the stomachs work together to break down food so that the animal can absorb the nutrients.
