Abstract
At the end of gastrulation the outer layer of the embryo and yolksac consists of ectoderm1. In teleosts it is often referred to as ‘epiblast’ (to contrast it with the inner layer, the ‘hypoblast’). The ectoderm covering the embryonic shield is greatly thickened compared with the extraembryonic area and it undergoes neurulation as described in Chapter 12. Eventually the whole embryo and the yolksac become covered by the one-layered epidermis topped by a flattened layer, the EVL or periderm (Chapter 11).
‘Discovery consists of seeing what everybody has seen and thinking what nobody has thought.’
