Noah's ark shell
A species of ark clam (Arca noae). The Japanese name literally means 'Noah's ark shell', referring to the boat-like shape.
The Noah's ark shell is a bivalve that lives in the Mediterranean Sea.
All-katakana spelling, often used in biological contexts or for clarity.
From ノア (Noah) + の (possessive particle) + 方舟 (ark) + 貝 (shellfish). Named after the biblical Noah's Ark due to the shell's resemblance to a boat.
