• Adult Heliocidaris erythrogramma (He) (50g wet body weight) and H. tuberculata (Ht) (200g wet body weight) are compared. The relative sizes of the test and spines are the same for both species, but that of the Aristotle's lantern is 2-fold larger in He. The gonad index shows no sexual differences and is similar for both species (He : 10, Ht : 12). The proximate composition of the gut, Aristotle's lantern, test, and spines of both species are similar. The percent organic material in the ovaries of He is greater than in the testes and in the ovaries and testes of Ht. Lipid is 50% of the dry weight of the ovaries of He, twice that in the ovaries and testes of Ht. DNA is 6% of the dry weight of the testes of He, half that in the testes of Ht. The direct development in He and indirect development in Ht is correlated with differences in body size and proximate composition of the gonads.
