Flatworm Swimming

These shots were taken while on a safety stop at the end of a dive this morning off the coast near Fremantle. Flatworms are common in the ocean and they are soft bodied invertebrates with no body cavity. They absorb oxygen and nutrients through their skin and come in a variety of sizes and colours.  They are very attractive while they swim freely with an undulating movement.
