Do you have a swim bladder?

Answer 1

No, I don't have a swim bladder.

Answer 2

I am a bottom dweller and don't need a swim bladder to  maintain buoyancy, unlike the Danio hiding underneath me.

Answer 3

Organisms from class ostreichthyes (bony fish) have a swim bladder while organisms from chondricthyes (ratfish, sharks, and rays) do not have a swim bladder. Instead they have oils in their liver that helps them maintain buoyancy.

Answer 4

No. But, I do have an enlarged prostate. I wee wee many times a night.
