Moon clams are really, really weird. They live with their shell permanently open on their back like a snail, and move around on their foot. Their soft mantle extends over their shell, so they end up looking a lot like cowry snails. They are found in Western Australia, where they live symbiotically in the burrows built by shrimp. Many members of their superfamily, Galeommatoidea, are symbiotic with other creatures. Some others in the family can also use their foot for snail-like locomotion, but moon clams are unique in how much they're committed to the "nothing to see here, I'm a snail" bit. Just weird little guys! #clamFacts https://www.colorado.edu/today/2026/04/10/moon-clam-vies-mollusk-year-thanks-cu-researcher
