The Sea Urchin Embryo Biochemistry and Morphogenesis
Sea urchin eggs are objects of wonder for the student who sees them for the first time under the microscope. The formation of the fertil ization membrane after insemination, the beauty of mitotic cleavage, the elegant swimming of embryos, remain an esthetic pleasure even for the eyes of seasoned in...
