PARTHENOGENESIS IN CARCINONEMERTES SPP. (NEMERTEA: HOPLONEMERTEA)
The Biological Bulletin, 1986 When juveniles of Carcinonemertes spp. are removed from male crabs and raised in the laboratory, a 50:50 sex ratio is obtained. Isolated females produce egg strings typical of Carcinonemertes, except that the embryos are haploid, with about 13 chromosomes per cell. Larvae develop at least to hatching, and some do hatch. Nearly all of the 146 females so
