Fig. 2.17 Types of ooecium formation in: ( A , B ) Callopora craticula ;
( C ) Corbulella maderensis ; ( D ) Callopora dumerilii . ( A ) Ooecia
formed by ‘interzooidal’ avicularia at the periphery of the colony (basal
view). ( B ) Ooecium formed by distal kenozooid (basolateral view).
( C ) Fractured ooecium (at right ) with roof missing, formed by a distal
kenozooid with prominent frontal part. ( D ) Ooecium and two adventitious avicularia formed by a distal kenozooid (adjacent ooecium formed
by a distal autozooid can be seen above it in same photo) (( A–C ) –
