We have only collected two types of megalopae at this site, this one and a much smaller one which has been attributed to Bythograea microps (on the right). The size difference should be sufficient to distinguish the two species
Typical brachyuran megalopa, reddish in life, but generally tan to whitish in preservative. The zoea is similar to those collected from B. thermydron females and we believe it also belongs to this species.
