On 12-08-2012, a rare occurrence of Blue ring octopus (Hapalochlaena nierstraszi (Adam 1938)), with a length of 82-165 mm and weight of 5.5-18 g was recorded for the first time at Kasimedu Fisheries Harbour , Chennai. It was caught by Trawl net gear at a depth of 20-30 m in Bay of Bengal along the Chennai Coast. There are about at least ten species of tiny blue-ringed octopus, which, ironically for their size, are the most deadly of ail cephalopods,but only four have been formally named. All these are inhabitants of Asian-pacific waters. These are; Greater Blue-ringed Octopus (Hapalochlaena lunulata), Lesser Blue-ringed Octopus or Southern Blue-ringed Octopus (Hapalochlaena maculosa), Blue-lined Octopus (Hapalochlaena fasciata) and Hapalochlneno nierstraszi. The common names come from the bright blue rings that appear when they are alarmed or attacked.
