Hi Seano.  I forwarded your enquiry to the Australian ray authority, Dr Peter Last.  He kindly replied that it is very hard to be sure but the 187 mm Black Stingray stinging spine in the image would probably have come from a fish of disc width 1.0 to 1.5 m.  The spine is not particularly large compared with that of the Smooth Stingray.

Hi Seano.  That is an interesting question, but not one that is easy for me to answer.  I'll have to ask a stingray expert and get back to you.  Watch this space.

how big would this black ray be with a 187mm stinging spine ? because I know someone with 2 stinging spines twice as big.
