Contrasting modes of reproduction in two Antarctic asteroids of the genus Porania, with a description of unusual feeding and non-feeding larval types

This paper describes differences in reproduction and development between Porania antarctica and Porania sp. that substantiate Clark's (1962) recommendation of distinct species rankings for the two forms. The findings of this study are compared to general patterns of reproduction in other echino...

Description
Summary:This paper describes differences in reproduction and development between Porania antarctica and Porania sp. that substantiate Clark's (1962) recommendation of distinct species rankings for the two forms. The findings of this study are compared to general patterns of reproduction in other echinoderms and discussed in the context of life-history evolution.
