Matt Walker of the U.K.’s Independent Online reports a startling anthropomorphic behavior among brown trout: faked orgasms. “Female brown trout (Salmo trutta) fake orgasms to encourage males to ejaculate prematurely. By doing so, they dupe their partner into thinking it has successfully mated, before the female fish moves on to find a better male with which to do the real thing.”
