Most echinoderms have a feeding larval form, the pluteus larva, but some develop directly into an adult urchin.
When they reached the pluteus four-arms stage, larvae were fed twice a day ad libitum with a mixture of Pavlova lutheri, Chaetoceros calcitrans, and Isochrysis galbana.
For RNA-Seq, samples of larvae fed ad libitum were flash-frozen at 2 days post-fertilization (dpf) (gastrula), 6 dpf (pre-feeding pluteus), 13 dpf (6-arm pluteus), 22 dpf (8-armed pluteus with rudiment), and 27 dpf (8-arm pluteus competent for metamorphosis); samples of diet-restricted larvae were flash-frozen at 2 dpf (gastrula), 7 dpf (pre-feeding pluteus), and 38 dpf (6-armed pluteus).

In additional studies, we found that these antagonists protected the late larvae (prism and pluteus stages) from chlorpyrifos-induced lethality.
Many marine invertebrate groups with different adult forms have similar larvae (such as the trochophore larva of mollusks and annelids, or the pluteus larva of sea urchins and brittle stars), and these similar larval forms are usually considered to be examples of either convergent evolution by natural selection or functional constraints on the evolution of early stages in development (Jagersten 1972; Strathmann 1988; Raff and Kaufman 1991; Wray 1992, 1995).
