"Very good Serena and Francis, the Firefly Squid uses it's photophores as a type of hypnotic ability to create a state of confusion to both its prey and to escape from predators. This is a very unique creature because it is one of the few underwater creatures that can be domesticated, much like a dog or cat. Now, if I'm not mistaken, when a Mereperson decides to domesticate a Firefly Squid, they are supposed to remove several of the photophores along it's body and tenticles. This greatly reduces it's hypnotic effect. Merepeople have been know to adhere them around their necks like jewelry. Though I would caution anyone addressing a Mereperson wearing a Firefly Squid. Beacuse it's hard to tell if any of the photophores have been removed, until it's too late, Merepeople who wear them are often....how can I say this...of lesser social standing?....Well, they should not be trusted. They tend to manipulate others into doing what they want."

Pausing for a moment, the Headmaster says, "Now are there any other questions before I assign homework?"
