-
03Biologists age them by sectioning that quill-like fin ray and reading growth rings like a tiny tree.
-
04Serial hybridizer alert: they frequently cross with other carpsuckers, producing maddeningly in-between shapes.
-
05The mouth sits so forward they'll sip drifting insects like trout when the buffet floats by.
