What are the similarities and differences between the Giant Clam (Tridacna squamosa) and the Maxima Clam (Tridacna maxima)?
The Giant Clam and the Maxima Clam are both marine (saltwater), bivalve molluscs in the Cardiidae family. Bivalve means two valves (or two shells). They both prefer to live on the bottom of the ocean in shallow coral reefs.
The Giant Clam and the Maxima Clam both have a thick, ridged calcium carbonate shell, called a mantle. Their shells, which can open and close, have two equal-sized calcareous valves connected with a flexible adductor muscle.

The Maxima Clam (Tridacna maxima) is a marine (saltwater) bivalve mollusc in the Cardiidae family. It is also called the Small Giant Clam. It is related to the Cockle.
The Maxima Clam has a thick shell called a mantle. Its shell is actually two equal-sized calcareous valves connected with a flexible adductor muscle. The shell can open and close. Bi-valve means two valves (or two shells). The mantle is bright-blue, green, or brown with distinctive furrows. It has a mouth, a heart, kidneys, a stomach, and a nervous system.

The Round Mouthed Snail (Pomatias elegans) is a small, air-breathing, terrestrial (land) gastropod mollusc in the Pomatiidae family of operculate land snails. It is an invertebrate, because it does not have a backbone. Its shell is its exo-skeleton (outside skeleton).
The Round Mouthed Snail has a thick, whitish, conical shell and wide mouth with a chalky operculum (lid) at the rear of its body. The shell forms a whorl. The top of the spire points upward and the opening of its mouth is on the right – so it has a right-handed whorl, which is called a dextral shell. It can close its shell’s mouth with its lid. Its head extends to form a snout (proboscis). It has only one pair of tentacles on its head (instead of two pairs). Its eyes are at the tip of the tentacles.
