Palm Tree and Anchor Hold Calypso Fast off Sao Tome To explore the specimen-rich S waters near this Portuguese is land in the Gulf of Guinea, the ship moored off the beach and ran a stern line ashore. Calypso, flying the Tricolor of L France, rides beside slopes thatched with coconut palms. Divers worked from a ladder at the stern. Naturalist Maurice Denizot probes for specimens among corals dredged from the bot tom. Bushlike formations are gorgonians, relatives of reef coral. Red-orange Tubastrea corals lose brilliance out of water when pigments oxidize. Brilliant wrasses and snap pers (opposite, lower) form a carousel around a gorgonian 80 feet below the surface. Another wormlike gorgonian lies in foreground. Red ani mals on the bottom are spiny oysters, Spondylus. School of surmullets browses above banks of coral and sponge 65 feet down.
