These flower-like animals, up to 2.5 cm (1") across, feed on invertebrates which they have paralysed with nematocysts and caught with their 100 ball-tipped tentacles. They favour fast-flowing water, so look for them where strong currents occur from shore level down to around 50 m. The reason for the large patches of jewel anemones is their capacity for asexual reproduction. The adult anemone splits itself longitudinally into two which when repeated forms large colonies. Water pressure inside the body maintains the anemone's shape and provides a base for muscle action Different species of jewel anemones are found in temperate waters around the world. Corynactis viridis occurs around the British Isles, South West Europe and in the Mediteranean. C. californica (also known as the strawberry anemone) is found from San Diego to British Columbia. C. autralis lives around South East Australia. Photo credits: Tim Nicholson. More of Tim's photos are on the SCUBA Travel website.

For breaking news see our Twitter page or RSS feed Fish eat bits of plastic because they think they smell good Hungry fish are gulping down mouthfuls of plastic, perhaps because it smells like their favourite food Weird creatures are spreading polluting plastic through the sea Plastic particles sink to the seabed after being eaten and excreted by animals called larvaceans, which could be why we see less floating plastic than expected. Sea Snakes are turning black in response to industrial pollution Pollution from mining activities may be encouraging some sea snakes to evolve black skins - the first evidence of "industrial melanism" in a marine species. Whales turn tail at ocean mining noise Study measures the effect of loud sounds on migrating humpback whales as concern grows as oceans become noisier. Warmer waters from climate change will shrink fish Fish are expected to shrink in size by 20 to 30 per cent if ocean temperatures continue to climb due to climate change. Fish exposed to oil make risky choices emphasises the risks of increasing industrial activity in areas like the Great Barrier Reef. Some Tuna can carry up to 36 times the toxic chemicals of others A new study may prompt hand wringing among tuna lovers. When it comes to pollutant levels, researchers now say where your tuna was caught matters. A tiny fraction of oceans could satisfy the world's fish demand Covering 70 percent of Earth's surface, the world's oceans are vast and deep. So vast, in fact, that nearly every coastal country has the potential to meet its own domestic seafood needs through aquaculture. In fact, each country could do so using a tiny fraction of its ocean territory. SCUBA News is licensed under a Creative Commons Attribution 4.0 Unported License.
