http://www.biolbull.org/cgi/reprint/210/... The asterinid sea
star Parvulastra exigua (Lamarck) is a common member of
temperate intertidal marine communities from geographically
widespread sites around the southern hemisphere. Individuals
from Australian populations lay benthic egg masses (through
orally directed gonopores) from which nonplanktonic offspring
hatch and metamorphose without a dispersing planktonic larval
phase. Scattered reports in the taxonomic literature refer to a
similar for
