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.”
