A review of echinoderm oogenesis
Journal of Electron Microscopy Technique, 1990AbstractThis review of the anatomical, histological, biochemical, and molecular biological literature on echinoderm oogenesis includes the entire developmental history of oocytes; from their inception to the time they become ova. This is done from a comparative perspective, with reference to members of the five extant echinoderm classes; crinoids ...

Pentamerism and the ancestral echinoderm

Nichols1 has proposed a hypothetical ancestral echinoderm derived from a lophophorate ancestor. Sipunculoids have a recurved gut and a hydraulically operated tentacular system using a special compartment of the coelom.
