Opisthobranchs are known to gastrulate by a variety of methods including epiboly and emboly, or some combinations thereof (Thompson, 1958; Gohar and Soliman, 1967a, b; Williams, 1971; Soliman, 1978; Verdonk and Biggelaar, 1983; Schaefer, 1997).
More importantly, Nusse and his colleagues determined that Wnt-responsive cells in the embryoid bodies also spontaneously form a primitive streak, though they never truly gastrulate.
The mode of gastrulation correlates with the amount of yolk: yolky embryos gastrulate by epiboly; non-yolky embryos by invagination (Okada, 1970).
palmata embryos appeared to gastrulate via invagination, as has been described for other Acropora spp.
