Description:
This video shows the life cycle of the sea biscuit Clypeaster subdepressus and is part of my master's thesis project at the Biosciences Institute of University of São Paulo.nnWe collected adults from sand beds of São Sebastião Channel (São Sebastião, SP, Brazil) and induced gamete release (eggs and sperm). We did the fertilization in vitro and followed the embryonic development in the laboratory, under light microscopy. Embryos become swimming larvae, approximately 0.2 mm wide, which we fed
