One of the interesting things about human structures built in the ocean is they can provide additional habitat for animals and plants. This can be an artificial reef made from a ship, an oil rig, or a pier or jetty. All provide extra surface area for invertebrates like anemones, corals, barnacles, and sea stars to make their home, in turn creating habitat for countless other little critters. I timed this dive at Argonaut Wharf for a good slack tide on a clear day at sunset. I love spending time in the shallows playing with the dappled light sparkling through the water, and the numerous colourful invertebrates around, including this colourful ochre star!
