Clams feed from safety using siphons

Clams burrow deep into sandy or muddy ocean floors for protection, but how do they eat? They extend specialized tube-like siphons to the surface, acting like snorkels. One siphon draws in nutrient-rich water, which the clam filters for plankton and organic matter. The other expels waste and clean water. This clever adaptation allows clams, like the common soft-shell clam, to stay hidden from predators and harsh currents while efficiently feeding. They can burrow several inches deep, thriving in dynamic intertidal zones and playing a vital role in marine ecosystems.
