## Abstract The hyaline layer (HL) is an apically located extracellular matrix (ECM) which surrounds the sea urchin embryo from the time of fertilization until metamorphosis occurs. While gelatin‐cleavage activities were absent from freshly prepared hyaline layers, a dynamic pattern of activities d
