However, periodic variability in food level can also significantly affect
pluteus arm length.
Failed cloning was documented in this study with the production and rapid disintegration of an embryo-like bud on the aboral surface of an experimental
pluteus (Fig.
The time required for developmental stages (prism, 2-and 4-arm
pluteus) to be completed, was also estimated by the duration taken for at least 50% larva to achieve the particular stage (Fujisawa, 1993; Rahman et al., 2002).
For biochemical analyses, we used the material from 22 ripe females at the following stages: unfertilized eggs; embryos at 2-4 blastomeres (2 hr postfertilization), 16 blastomeres (3 hr), early blastula 1 (4.5 hr), and mid-blastula 2 (9.5 hr); and larvae at late blastula 1 (12 hr), prism 2 (25.7 hr), early
pluteus 2 (34.3 hr), and mid-pluteus 1 (47.5 hr).

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).
At hatching, these embryos separated from one another and swam apart as distinct individuals that proceeded to form normal
pluteus larvae.
