From: Life cycle of the cold-water coral Caryophyllia huinayensis
Haematoxylin-eosin-stained longitudinal (a, b) and transverse (c) histological sections of two larvae inside a polyp of Caryophyllia huinayensis. (a) Planula showing the epidermis (ep), the pseudo-stratified epidermis (pse), a thin layer of mesoglea (m), and the endodermis (en). Note that the mesenterial filaments (me) are attached to the pharynx (ph), which in turn is connected to the blastopore/oral pore (*), shown in detain in (b). (b) Detail from (a) showing a ciliated (ci) oral pore connected to the pharynx. (c) The gastrovascular cavity opening (gco) and the uniform ciliated epidermis are visible.
