The common Sydney octopus does not look like a happy chappy, but he always looks gloomy. It is just the way he is. Not doing so well in the sea around New South Wales he has moved down to the cooler waters off Tasmania. Because they increased in number from a few early arrivals their genetic diversity is less than those on the east coast. More are arriving from NSW and Victoria so things are improving. The exodus began in the mid-2000s. A joint project between James Cook University, the Centre for Marine Socioecology (CMS) at the University of Tasmania and the Institute for Marine and Antarctic Studies (IMAS) is researching the genetics of the species. Gloomy octopuses have been found as far south as the waters near Hobart. A new study, published in the journal Scientific Reports, suggests the species is thriving in Tasmanian waters with a healthy mix of genes from local and interstate populations. The species, also referred to as the common Sydney octopus, or octopus

Jellyfish are spineless little devils. I do mean that in a good way. They are the most efficient swimmers on Earth, pulling their way forward rather than pushing. The "immortal jellyfish" rises phoenix-like from the dead. When it dies the decomposing body puts out stolon stalks which become babies. They are rapidly increasing in the world's oceans due mainly to Man. Most variations breed under man-made marine structures such as piers. The killing off of predatory fish for human food allows the transparent creatures to vastly increase in number. Cyaneidae have caused many problems over the years. Those going for a swim regularly get stung. In 2006 the seemingly invulnerable USS Ronald Reagan was put out of action by masses of jellyfish clogging the cooling system. Power plants and desalination facilities have also been stalled. Two million workers became unemployed when the comb jelly native to North America invaded the Black Sea in 1980 and destroyed anchovy
