The Same Upside Down

A word of five letters,
Upside down is the same,
A shark does this,
But it’s not to blame.
What is the word?

ANS - SWIMS

If you turn the word upside down it’s the same word (the W and M flip to resemble themselves). A shark swims to attack, but it’s not bad. Sharks are just trying to eat. I’d still recommend you swim away if you see one swimming toward you.
