New species of wood-munching (and phallic-looking) clams found at the bottom of the ocean

When a tree falls in a forest, regardless of whether anyone hears it, it sometimes becomes clam food. Wood that finds its way from rivers into the ocean can eventually become waterlogged and sink to the sea floor, sometimes to great depths. There, tiny clams bore into the wood, eating the wood shavings and living the rest of their lives head down in the holes they made.
