Underwater photograph of Astichopits nntltifidits at the edge of a bed of the seagrass, Ifulnpliilii huilloiiix, in 15 m. of water at Crashboat Landing, Aguadilla (November 20, 1964). Tlic length of this animal, as it is crawling in the picture, was approximately 35 cm. Forward i> toward the right; visible are the cloacal aperture at the rear end of the animal to the left and a lateral fringe of papillae bordering the ventrum. Synaptidae, whose members possess calcareous spicules in the form of anchors and anchor plates and tentacles with slender digits. The observations reported in this study were made on animals living in Monterey Bay, California. Limited studies were carried out on Synaptitlu Jiydrijonnis (Le Sueur, 1823), a viviparous member of the Synaptidae. This is an abundant species of the West Indian fauna, usually living a-vsociaied with algae. All specimens were collected from the red alga, Lanronia /v//>;7/».w/. \\hich grows on a sandy bottom in the shade of red mangroves (Rhizophora nnintjlc'} on the reef flat at Cayo Majimo, La I'arguera, I 'uerto Rico. ;e different methods were employed in the various experiments per- formed, are discussed separately under the appropriate, sections to Please note that these images are extracted from scanned page images that may have been digitally enh
