General introduction
some features of echinoderms, namely the "position, size and the method
of formation of the skeleton" and "the substitution of collagenous tissues
for muscles", in addition to their low metabolic rate may have given them
competitive advantages over other animals. Among echinoderms, sea
urchins are the more mineralized ones, and their competitive advantage in
some marine ecosystems could probably be summarized by "bone idle – a
recipe for success" as proposed by Emson.

Figure 6: Location of the sampled Paracentrotus lividus population.
Echinoids reared in the Luc-sur-mer facility originated from a single
population in Morgat, Brittany, France (Fig. 6, but see also Fig. 1). They
were collected at low tides from tidal pools. Individuals used in these
experiments were first or second generation sea urchins reared from the
egg.
