  • Ophidiaster granifer Lütken is a small cryptic coral reef asteroid found in the Indo-West Pacific. Its mode of reproduction, shown by aquarium observations and gonad histology, is parthenogenetic. This is the first confirmation of natural parthenogenesis in the phylum Echinodermata, despite many studies showing artificial parthenogenesis in echinoderms. Populations of O. granifer from Micronesia, New Guinea and the Great Barrier Reef consisted only of females: no testes or spermatogenesis were… CONTINUE READING
