Best Answer

The Spiral Valve is the lower part of a shark's intestines. It is internally twisted to allow a greater surface area for digestion and increased nutrient absorption.

The level of absorption is so great that the food leaves almost completely digested. Because the sharks absorb so much from their food they feed less frequently, which fits in perfectly with their oppotunist hunting style of preying on weakened fish.
