(science fiction, short story) Because mermaids lay eggs, hundreds at a time, at least that kind did. And the natural-born ones, they didn’t have human minds guiding them. They were like sharks—they ate, they killed, they ate. Most of the original human mermaids had gotten out when they found out that the seas were full of chemicals, or that instead of whale songs down there, they heard submarine sonar and boat signals. When the last few found out that they were spawning whether they liked it or not, they got out too. Supposedly one or two stayed, and now they live in the sea with their children, twice as mean as any of them.
