Maybe a stupid question but i was just wondering, are the small spikes on a rays tail as venomous as the stinger? Are the small spikes venomous at all? I know its the skin on the stinger that holds the venom. But the skin on those small spikes looks a bit different to me. Never heard or read something about it, so i thought let ask it you guys
