That looks like a juvenile grey nurse....Lots of fun on light gear !!

Not sure what a juvenile grey nurse is... is that what you call them over at the ditch? ? I guess you might get them in the cooler waters of Tasmania. No had a look - definitely not a grey nurse :-) Grey nurse looks more like what we'd call a bronze whaler and they would grow huge. Probably not edible either. This is a rig shark or alternatively called a smooth hound. A small sand shark that predominantly feeds off crustaceans. They don't get massive. Although this is definitely a smaller one. Mainly found in the cooler waters around the South Island. Bonus - they don't have teeth. One of the edible and actually very good tasting shark species. Over here they sell them in the fish and chips shops as Lemon fish. I actually prefer them over snapper as the meat is a bit firmer but not dry and very versatile to use in all sorts of fish dishes.
