What is the function of the colon in sharks?

How Is sharks digestive system different than humans?
Sharks have U-shaped stomachs that use very strong stomach acids and enzymes to dissolve most of what is eaten. The digestion in the stomach is also different from humans because of the differentiation in diet. Our system does not require as strong stomach acids and enzymes because we eat lighter foods than sharks.
Do sharks have tongues?
Yes, sharks have a tongue, and it is referred to as a “basihyal” rather than a tongue. A shark’s tongue cannot move in the same way that a human tongue can since it is not a muscle.
