How does the small intestine of a dogfish shark compare to the small intestine of a mammal?

The small intestine of a dogfish shark is relatively shorter and more simplistic compared to that of mammals, reflecting their different dietary needs and digestive processes. While dogfish sharks primarily consume a diet of fish and other marine organisms, requiring less extensive digestion, mammals often have a more complex small intestine with specialized regions for nutrient absorption due to their diverse diets. Additionally, the lining of a mammal's small intestine features more pronounced villi and microvilli, enhancing its surface area for absorption. Overall, these differences highlight the adaptations of each species to their specific feeding strategies and environments.
