Antrosagittifera corallina Hooge and Tyler, 2001

( Fig. 33 View FIGURE 33 )

Material. Living specimens in squeeze preparation; one set of serial sections of epoxy-embedded specimen stained with toluidine blue.

Locality. Islas Zapatillas (9°15’N, 82°03’W), from coarse-grained sand at 2 m water depth taken from the west side of the more westerly island.

Description. Mature specimens ~400 µm long and ~110 µm wide ( Fig. 33 View FIGURE 33 A). Anterior and posterior ends rounded. Greenish-brown color conferred by numerous zooxanthellae.

Paired strands of oocytes extend posteriorly from frontal glands to seminal bursa with bursal nozzle ( Fig. 33 View FIGURE 33 B).

Male gonopore subterminal at posterior end. Long male antrum opens to walled seminal vesicle.

Sagittocysts most easily visible at posterior end of body, behind seminal vesicle, where zooxanthellae are mostly absent ( Fig. 33 View FIGURE 33 B).

Remarks. Antrosagittifera corallina is the only member of the Sagittiferidae known to occur in the Caribbean. The type locality of this species is in Bermuda ( Hooge & Tyler 2001), but other specimens have been reported from Carrie Bow Cay, Belize (Hooge & Tyler 2006).
