Colony encrusting, uni- to multilaminar, the latter forming forming large mounds. Skeleton red. Zooids of initial layer subrectangular, those from frontally budded layers irregularly polygonal, longer than wide, limited by slightly raised lateral walls. Frontal shield heavily calcified, marginally punctured by 7–14 pseudopores. Primary orifice small relative to frontal shield, transversely D-shaped, wider than long, sunken, with arcuate anter and straight or weakly convex poster. No condyles. Secondary orifice surrounded by 4–6 (usually 4) whitish solid tubercles. Suboral elliptical avicularium laterally orientated. Interzooidal avicularium large, wider than long, rostrum obovate; calcified palate occupies more than half rostral length; foramen rounded. Ooecium subglobose, initially seen as horizontal on zooid surface before becoming partly immersed in secondary calcification, wider than long; ectooecium with frontal semicircular membranous area.

Scale bars = 1 cm. Remarks. According to Winston (2005) , Smitt (1873) did not differentiate T. aviculifera from Celleporaria albirostris . Osburn (1940) also misidentified T. aviculifera as Trematooecia turrita ( Smitt, 1873 ) (= Cigclisula turrita ; Fig. 11 ), and erected the genus Trematooecia for this species. Both T. aviculifera and C. turrita species have heavily calcified, encrusting colonies, often with a tubercular secondary orifice. They are distinguished, however, by the morphology of ooecia and avicularia (see above, under Remarks on Trematooecia ). Canu & Bassler (1923) described T. aviculifera based on a fossil specimen (USNM 68709; Fig. 19 ) from Panama Canal. They described small frontal avicularia, but none has been found in examined material. Trematooecia aviculifera is characterized by the transversely D-shaped orifice, suboral elliptical avicularium laterally directed and obovate interzooidal avicularium. TABLE 5.

1 USNM 68709, Pleistocene, Panama Canal. 2 USNM 603782, Panama. 3 USNM 376606, Belize. 4 USNM 603776, Curaçao. 5 USNM 603778, Belize Trematooecia aviculifera resembles Trematooecia osburni Marcus, 1955 , Trematooecia protecta Osburn, 1940 and Trematooecia ridleyi (Kirkpatrick, 1890) in having encrusting colonies, a marginally punctured frontal shield, globose ooecium and ectooecium with a frontal circular membranous area. Trematooecia aviculifera differs from T. osburni in the presence of tubercles around the secondary orifice and in having a suboral avicularium. Trematooecia aviculifera differs from T. protecta in the absence of condyles and frontal avicularia and in the position of the ooecium (inclined in T. protecta , horizontal in T. aviculifera ). Autozooids, suboral avicularia and ooecia are also shorter in T. protecta than in T. aviculifera ( Table 3 ). Trematooecia aviculifera differs from T. ridleyi in the size of the zooids and ooecium (all smaller in T. ridleyi ) and in the absence of frontal avicularia (conspicuous in T. ridleyi ). Trematooecia aviculifera has been reported by some authors ( Canu & Bassler 1928a ; Osburn 1914 , 1927 , 1940 ; Banta & Carson 1971; Winston 1984 , 2005 ) from the Gulf of Mexico, Florida, Puerto Rico , and Costa Rica . This species is probably one of the most abundant bryozoans on Caribbean coral reefs ( Winston 1984 , 1986, 2005). Colonies grow from a single lamina to form large mounds that remain red even when dead ( Fig. 24 ). Because of the colony color and presence of tubercles, the species is also called “bleeding teeth bryozoan” ( Charpin 2014 ). Owing to some physical property of the calcification, the species has a fluorescent green coloration at depths below 7m ( Winston 1984 ), one of the reasons why T. aviculifera is easily noticed by divers. Distribution. Pleistocene ( Panama ) to Recent (Atlantic: Florida to Venezuela ).
