Northern Moon Snail - Moon Snail Predation

Moon Snail Predation

Evidence of northern moon snail predation is usually much easier to find than the snails themselves:

The powerful foot enables this gastropod to plow under the sand in search of other mollusks. Upon finding one, it "drills" a hole into the shell with its radula, releases digestive enzymes, and sucks out the somewhat predigested contents.

When empty shells of clams and snails, including other moon snails, are seen to have a neat "countersunk" hole drilled in them, this is evidence of predation by a moon snail.

Famous quotes containing the words moon and/or snail:

    The skreak and skritter of evening gone
    And grackles gone and sorrows of the sun,
    The sorrows of sun, too, gone . . . the moon and moon,
    The yellow moon of words about the nightingale
    In measureless measures, not a bird for me....
    Wallace Stevens (1879–1955)

    The snail in his museum
    wears his mother all day,
    he hides his mysterious bottom
    as if it were rotten fruit.
    Anne Sexton (1928–1974)
