Glow squids drop photophores

There is a type of glowing squid known as the firefly squid, they use photophores to glow. So I thought that the glow squid should drop 1-3 photophores on death. The photophores can be used to make potions of glowing, and a special type of torch that can be placed underwater. They could also be used along with dye to make coloured sea lanterns.
