Extract
There are few records in the literature of the relative proportions of the sexes in natural populations of echinoderms, and the samples studied have mostly been small. Selenka (1867) has stated that in Holothurians in general males are rarer than females, and Becher (1907) found that males were very rare in Rhabdomolgus ruber. Koehler (1907) noted that in the ophiuroidOphiacantha vivipara there were more females than males.
