These see-through sea cucumbers snuffle across the seafloor to find tasty morsels in the mud. Sea pigs (Scotoplanes sp.) are one of the most commonly sighted animals on the deep seafloor off Monterey Bay—but plentiful hardly means boring. Unlike most sea cucumbers, which have stumpy tube feet tucked beneath their bodies, sea pigs use their long, stilt-like tube feet to suspend their bodies above the soft mud.
