 A group of mud dog whelks grazing in the mud on a sunny day in May.  When the picture was taken, there were probably a million whelks grazing together - and making a loud slurping noise in unison.

Tidepool Tim says,  “This is the smallest whelk species we supply.  They are not native to our cold-water bays here in eastern Maine.  I collect them at my in-laws' place in Freeport.  They are complete scavengers that like to feed in the muddy bottom or sandy mud area and are omnivorous.  We sell a lot of these snails to aquarium enthusiasts cause they help keep their tanks clean sweeping up uneaten food, algae, other dead or dying organisms. They also make a good disposable food source for smaller sea-stars, hermit crabs, and fish.”
