Description.
Colonies encrusting, multilaminar (
Fig. 37
A), developing into mounds a few mm in size, pale pink when alive. Even young colonies that are still unilaminar are conspicuously raised above substratum because of their deep-bodied zooids. Zooids with irregularly polygonal borders and central orifice surrounded by 4–5 flattipped spiniform tubercles (
Fig. 37
D). Frontal shield granular, thickly calcified, with small pores scattered over surface. Orifice hoof-shaped, with evenly rounded anter and broad, shall poster demarcated by triangular condyles (
Fig. 37
E). Oval adventitious avicularia in two size classes, the smaller with serrated distal rostral margins, usually buried in peristome between or at ends of tubercles; the larger with enlarged, more-spatulate mandible and smooth rostrum. Ooecia immersed in calcification of spines and peristome, opening into peristome; with frontal grid of small pores. Embryos red.
Remarks.
Cigclisula turrita
-like forms have a long history in the Caribbean-western Atlantic, and have undergone considerable radiation. Almeida
et al.
(2014) revised the genera
Cigclisula
,
Trematooecia
and
Colatooecia
, placing them in the celleporid family
Colatooeciidae
.
Distribution.
Florida and Caribbean.
