I harvest siren venom. Siren venom has some medical uses, but it’s very tedious to get. To collect siren venom, one has to massage a siren’s hand to stimulate venom glands, then squeeze it out of the siren’s claws. Sirens can’t talk. Siren songs have no words, and are just nonsensical lullabies. It’s also possible to get venom from the siren’s teeth, but it’s dangerous as sirens become aggressive when touched on the face. You are a siren.
