    Echinoderms do not spend time caring for their young ones.

    They reproduce by sexual means, that is the combination of genetic materials from two separate individuals (male and female). The males provide the sperm and the females provide the eggs for reproduction. The sperms and eggs are propagated into water column, and fertilization takes place in the open water. Echinoderms commonly, leave their eggs and provide no parental care to the eggs. They don't take care of their young ones at all, however, some sea urchins incubates their eggs in special little pouches.
