The zygote then undergoes radial, holoblastic cleavage and forms a hollow coeloblastula.
Holoblastic cleavage is practiced in each of the approximately 31 phyla.
Although microtubules have been correlated with cytoplasmic movements that follow fertilization in amphibians (4), ascidians (5), and annelids (6), these embryos do not form blastodisc caps and, unlike the squid, they undergo complete or holoblastic cleavage. Interestingly, ooplasmic segregation, blastodisc cap formation, and meroblastic cleavage all take place in the zebrafish embryo, but here microfilaments and not microtubules have been shown to direct the segregation of ooplasm from the yolk (7).
