How does the mouth of a dungeness crab work?
The mouth of the crab is made up of hard pairs of mouth parts which have different uses. One pair of jaws holds the food; other mouth parts break the food into small bits and put them into the crab’s mouth. A flap on one pair of these mouth parts pumps water over the crab’s gills, so the crab can breathe while eating.
Why do hermit crabs squabble at the food dish?
Hermit crabs have small stomachs and are rarely gluttonous. Some hermit crabs may hoard food, though. This is a sign of dominance. This means that squabbles can break out at the feeding dish. Prevent hermit crabs from storing food in their shell, favored hiding places, or under the substrate. They will likely forget about their treasure.
