Scorpion

🦂Scorpions are organisms which can hold their breath for up to even 6 days.

🦂Scorpions are called arachnids, which are members of the animal kingdom's arachnid class.

🦂Their modified lungs, which are known as book lungs, also allow them to hold their breath for long.

🦂The scorpion's book lungs also have the shape of folded pages of a book, which is why they're named such.

🦂The book lungs also allow them to trap the most quantity of air which is possible throughout the air exchange process.

🦂This large reservoir of air also allows scorpions to survive & hold their breath for up to 6 days while they are underwater.
