It will be easier to respond to this question if we can get a little
more detail. For instance, what kind of sea urchin? The literature
includes sequences from Parechinus angulosus, Echinolampas crassa,
Strongylocentrotus purpuratus*, Lytechinus pictus*, Psammechinus
miliaris*, arbacia punctulata, Lytechinus variegatus*,
Strongylocentrotus franciscanus, and probably others, although
significant amounts of sequence information seems to be available only
for those followed by '*'s.
Are you interested in overall codon usage, or usage of highly expressed
genes? Are you interested in codon usage of genes expressed only
in early development (i.e. eggs), or at any time in the life cycle?
