China's Olympic beaches, choked by a plague of green algae. Sez David Suzuki: This is not an unusual occurrence, but it is a symptom of an underlying problem with potential repercussions far more serious than hampering Olympic events.

Invasion of the Jellyfish The box jellyfish [AKA Sea Wasp] is so packed with venom that the briefest of touches can bring agonising death within 180 seconds. And if comes under sustained attack it responds by sending its compatriots into a super-breeding frenzy in which millions of replacements are created. The really bad news is that the box jellyfish and another equally poisonous species, Irukandji, are on the move. Scientists are warning that their populations are exploding and will pose a monumental problem unless they are stopped. First aid for stings.

While the dream of immortality might be as old as mankind, the jellyfish Turritopsis nutricula (image) seems to be living it:

The hydrozoan Turritopsis nutricula has evolved a remarkable variation on this theme, and in so doing appears to have achieved immortality. The solitary medusa of this species can revert to its polyp stage after becoming sexually mature (Bavestrello et al., 1992; Piraino et al., 1996). In the laboratory, 100% of these medusae regularly undergo this change. Thus, it is possible that organismic death does not occur in this species!

An in-depth research paper.

Billions of jellyfish destroy a coastal fishery in Ireland. Next they will be attacking your children. Feel free to flee in terror...if you can.

Darling it's better down where it's wetter. For $2.5 million, this beautiful home can be yours: Jelly-fish 45, designed by Giancarlo Zema is a floating dwelling unit for up to six persons. It's spacious dimensions are 10 metres high with a diameter of over 15 metres. The Jelly-fish 45 would be ideally situated in sea parks, atolls, bays and seas rich in flora and fauna. The Jelly-fish 45 allows the sea dwelling owners to live either above or below sea level in perfect harmony with the ocean environment.

An "order of magnitude older than the dinosaurs," even older than clams, bugs, vertebrates, are jellyfish. At almost 600 million years old, jellyfish are some of the oldest animals on the earth that have survived the test of time. Dr. Lisa-ann Gershwin, (yes, of that Gershwin family) is a scientist studying jellyfish in Queensland, Australia and was recently interviewed by the ABC. I was particularly disturbed by her gripping description of the tiny Irukandji jellyfish and how the venom affects humans. This summer, swim at your own risk.

Australia is well known for having more than it's share of dangerous wildlife. However only a few examples are well known outside of the continent. The funnelweb spider might be Australia's most infamous horror. But the redback (a relative of the American black widow) and mouse spider both deserve your respect as well. Long hyped as causing severe ulceration, the reputation of the white-tailed spider might not be as deserved but is still a spider of concern. (more inside...)
