| Reproduction Preferences Additional Information | There is a great deal of variation within the genus for larval duration and egg size. Larger egg size corresponds with shorter larval period. There is also variation in the developmental mechanism with Grant & Tyler (1986) describing planktotrophic binnaria larvae for Astropecten irregularis and McEdward & Janies (1993) describing lecithotrophic larvae. | ||||||||||||||
