Final answer:
It is better to use a scalpel when cutting open a shark because of the precise and clean cuts it provides.
Step-by-step explanation:
When cutting open a shark, it is better to use a scalpel rather than scissors. Sharks have powerful jaws with multiple rows of sharp, saw-like teeth that are designed to tear through flesh. The scalpel, with its thin and sharp blade, allows for precise and clean cuts, ensuring minimal damage to the shark's body and organs.
