The Shell Exchange

The Shell Exchange is the story of a hermit crab named Matty, who runs a shell exchange for hermit crabs needing larger shells. The story is set near the Ningaloo Reef in Western Australia. Matty is helped by Occy the blue-ringed octopus, who runs the banking part of the business.

There are encounters with many of the marine creatures living in this part of the world, including anemone, sea-slugs (some of which are very beautiful), snails (whose empty shells are used by hermit crabs), fish and soldier crabs, as well as with humans.
