Final answer:
Birds do not have a large intestine; instead, they have a cloaca, which is a shared exit area for digestive, reproductive, and urinary tracts, reflecting a different digestive process than that of mammals.
Step-by-step explanation:
The animal that does not have a large intestine is the bird.
Birds possess a unique digestive system that differs significantly from mammals. Unlike mammals that have distinct large intestines, birds have a specialized structure known as the cloaca which serves as the common exit area for the intestinal, reproductive, and urinary tracts. Birds do have a small intestine, but the part that could be compared to a mammalian large intestine is extremely short or functionally different, and it is not referred to as a large intestine. Usually, the undigested food passes through a bird's digestive tract relatively quickly when compared to that in a mammal, which utilizes a large intestine for water absorption and the formation of feces.
