• Aldabra — One of the largest coral atolls in the world, located in the Indian Ocean, belonging to the Republic of Seychelles and designated as a UNESCO World Heritage site. The area is globally renowned for its pristine ecosystem, untouched by heavy human activity, hosting the world's largest population of giant tortoises (Aldabrachelys gigantea).
• Andros — The northernmost island of the Cyclades archipelago in the Aegean Sea, belonging to Greece, historically renowned for its mountainous landscape, abundant natural springs, and long-standing maritime tradition. This structural toponym also identifies the largest island in the Bahamas (Andros Island), famous for its barrier reef and blue holes.
• Sea anemone — A solitary marine polyp of the Anthozoa class, Actiniaria order, characterized by a cylindrical, soft, and muscular body attached to the substrate by a pedal disc, and a crown of stinging tentacles around the mouth opening. These predatory organisms use nematocyst cells to paralyze small prey and often live in symbiotic relationships with various species of fish or crabs.
• Anthozoa — A class of marine invertebrates within the phylum Cnidaria that includes stone corals, sea anemones, soft corals, and sea fans, characterized by the complete absence of a medusa stage in their life cycle, existing exclusively as polyps.
• Reef variant — A rare archaic, regional, or literary variant historically used to denote a reef, a rocky shelf, or a coral submarine structure located near the water surface. The term represents a transitional linguistic form borrowed directly from Mediterranean sources (such as Spanish 'arrecife' or Portuguese 'recife') in maritime travelogues and old maps from the 18th and 19th centuries.
• Atoll — A ring-shaped or horseshoe-shaped coral island, reef, or chain of islands surrounding a lagoon, specific to warm tropical seas. Atolls are formed over thousands of years by the accumulation of coral skeletons on the rims of extinct volcanic cones that slowly subsided into the sea.
• Refrigerated truck — A self-propelled transport vehicle (van, truck, or box truck) equipped with an airtight isothermal body and its own mechanical refrigeration plant (cooling unit). It is used in cold chain logistics for the road transport of perishable goods, such as frozen or fresh food, flowers, and pharmaceuticals, maintaining a constant controlled temperature.
• Bafflestone texture — A type of autochthonous carbonate sedimentary rock (limestone), according to the revised Dunham classification (Embry and Klovan), where the original organic components (such as fan-shaped corals or calcareous algae) grew together during deposition, acting as baffles that slowed down water flow and trapped fine sediment.
