What kind of food do crabs eat?
The sort of food a crab will need really depends on its species
and its habitat. Most crabs are aquatic and do not emerge onto land
very often, so most of their diet comes from what they can find
underwater. Most crabs are carnivorous, but some are omnivores. If
you are considering a crab as a pet, the pet shop will be able to
tell you what kind of food it needs. I have kept crabs caught from
the creek on mince and dog biscuits, but only for a few days.
