The eggs of many penaeoidean shrimp undergo two dramatic morphological events when spawned into normal seawater (Lynn et al., 1991). Following the initial release of jelly precursor from crypts in the cortex of the egg, an extracellular envelope elev

When chitin hydrolytic enzymes (chitinase and N-acetylglucosaminidase) were used as treatment during formation of the hatching envelope (HE) of the penaeid shrimp Sicyonia ingentis, results indicated the presence of carbohydrate moieties in the envel

The embryo of the grass shrimp, Palaemonetes pugio, is surrounded during development by a protective extracellular coat designated as the embryonic coat (EC). At hatching, this EC is composed of four embryonic envelopes (EE), each of which is compose

Experiments were performed in which developing embryos of the grass shrimp, Palaemonetes pugio, were exposed to conidiospores of the insect pathogenic fungus, Metarhizium anisopliae. Responses were variable, with significant ( P ≤ 0.05) adverse eff

Toxicity test procedures using grass shrimp Palaemonetes pugio exposed to water soluble fraction (WSF) of Number 2 fuel oil were modified to improve test utility and efficiency. The original test procedure, a 12-day embryo exposure period in glass tu

When penaeoid shrimp spawn into seawater, the ova elevate a hatching envelope (HE) within 30-50 min. By 60 min after spawning, the bilayered HE is completely formed. In other animal systems, peroxidatic enzymes are responsible for the hardening of th

The hatching envelope elevated around the spawned eggs of penaeoidean eggs presents a formidable barrier for manipulation of the embryo. By spawning eggs into seawater containing 3-amino-1,2,4-triazole and subsequently passing the eggs through Nitex

The structuralization of the sea urchin fertilization envelope (FE), a model for extracellular macromolecular assembly, was found to require sodium ions, the predominant cation of seawater. Eggs from Strongylocentrotus purpuratus activated in sea wat
