Shagreen ray, like all other rays and skate make excellent eating - a favourite in many people's eyes as they all have distinctive, meaty flavours. Hard to prepare, a fish that is much better left to the skills of your loocal fishmonger who will happily skin and trim your ray wings for you. If fish bones are a thing for you then ray wings are your go-to fish - being closely related to the shark family, the bones are cartilage ands easily removed or even eaten!
Shagreen ray are also one of those fish that have an interesting aspect to their place in the world of decorative fashionable items in that their skin has and in some places still is dried, cured and used as a material to adorn objects. The skin, like that of sharks has been used for centuries as a fine form of sandpaper to smooth and polish.
