ABSTRACT
Stages from oviposition to veliger hatching are described for Strombus pugilis under laboratory conditions. Two egg masses from Playa Seyba, México, (20 degrees 45' N, 91 degrees 45' W) were used (three sub-samples per mass). Each sub-sample was immersed in a 11 container at 29 +/- 1 degrees C. This description is based on stages known from Strombus gigas, which include number of: fertilized eggs, morulae, gastrulae, trochophore larvae with slow movements, larvae with primordium foot, larvae with eyes, larvae with statocyst and veliger larvae. Eggs with first division appeared five hours after oviposition in the three replicates of each mass, although in greatest number in one of the egg masses. Trochophore larvae with slow movements appear after 50-54 hours and veligers hatch after 90 hours.
