Noah's Ark

The ark in the site's name invites the obvious comparison — a vessel that carries a diverse collection of living things through difficult waters. Noah's Ark near Simonstown may take its name from a rock formation whose shape recalled the famous vessel to whoever first christened it, or from the specific diversity of marine life that the site harbors, or simply from the playful naming tradition of a diving community that enjoys giving its places memorable and slightly grandiose names. Whatever the origin, the name suggests abundance and variety, and in the productive waters of Cape False Bay, the implication is not misplaced. An advanced site near Simonstown, Noah's Ark occupies a position in the more challenging diving environment of the Cape Peninsula's southern coast. The advanced rating reflects the combination of cold water, potential surge, and the environmental variability that characterizes diving in this area — conditions that reward experience and appropriate preparation. For divers comfortable with Cape conditions, however, the site provides the marine life richness that the ark metaphor implies. The diversity of marine life at a Cape reef site like this one reflects the extraordinary species richness of the Cape bioregion's temperate waters. Sponge diversity alone — the Cape is internationally recognized for having some of the world's highest sponge species richness — provides the foundation for a food web of considerable complexity. The nudibranchs that feed on Cape sponges are themselves among the most diverse groups, with species that range from tiny, cryptic forms to the large, colorful animals that Cape macro photographers seek systematically. Feather stars and crinoids add to the echinoderms that complement the sponge community on Cape reefs. Fish diversity at Noah's Ark reflects the Cape's mix of temperate and subtropical species in the False Bay environment. The seven-gill cow shark — the bay's signature predator — may be present, resting in caves or cruising the reef. Spotted gully sharks inhabit the reef crevices. Pyjama catsharks and leopard catsharks add to the elasmobranch count. Roman, hottentot, Cape knifejaws, and galjoen represent the reef fish community. The Cape octopus — master of the reef's terrain — hunts with the intelligence that makes this species the cognitive standout of any Cape reef dive. The name Noah's Ark, with its promise of variety and refuge, captures something authentic about what Cape reef diving offers when conditions allow its marine life to be properly observed. The specific combination of sponge diversity, elasmobranch richness, and the endemic fish community of the Cape bioregion makes a well-planned, properly equipped dive at Noah's Ark a comprehensive encounter with what makes this particular corner of the underwater world so exceptional.
