• Resumen

  • Female lampreys mate hundreds of times but secretly withhold their eggs until they are sure their suitor is worthy. During the mating season, male and female Siberian brook lampreys (Lethenteron kessleri) meet for orgies in specially built nests in the streams where they live. Individual female fish appear to mate up to 200 times, with 10 or more different males.
