Two fish are speaking with one another underwater. One of the fish is just bones.
The fish on the left should be dead since it's only bones.
Why is he only skeleton?
It’s mostly water weight.

"Water weight" is often a reason people cite for being overweight.   But here, the fish skeleton is extremely skinny, so it's a weird but topically fitting thing to say about its weight because they are underwater.
