Most jellyfish in Australia are harmless gelatinous creatures with umbrella like bodies and flowing tentacles. However, the box jellyfish, found in tropical Queensland, are extremely nasty. Called stingers they can inflict excruciating pain and even death from a single brush. In the wet season (November to April) they live off the coast and swimming is only advised in enclosed areas (most beaches have these).

Moon jellies are certainly the most common, but several others occasionally make landing. Portuguese man-of-war can often be blown in with a strong storm from the South. Sea Nettle, Mushroom Jellies, and cabbage Head Jellies are also known to be off the coast and can be blown into shore. Lions Mane Jelly Fish are among the rarest to wash up. They can be as large as 8 feet across and have tentacles 100 feet long. See similar questions...

Without special safety precautions, the laser can be dangerous. However, we ensure patient as well as health care worker safety by: 1. providing safety glasses for everyone in the room; 2. using the lowest effective settings possible; and 3. only allowing the doctor to perform the procedure as per the State Board of Medical Examiners. At the very low energy settings we use to treat spider veins, the danger is minimal. Treatment for vein problems have advanced dramatically over the past 5 years. See similar questions...

Based on the number of attacks on people, the most dangerous sharks are the Tiger shark, bull shark, Great white shark, the oceanic whitetip shark. If a Tyrannosaurus got into a fight with a Triceratops, which dinosaur would win? I think we have all wanted to know this for a long time. I would bet on T. rex. A T. rex coprolite (fossilized dung) was recently found and it contained crushed Triceratops frill bone, so we know that T. rex ate Triceratops. It's unknown whether the T. See similar questions...

Dr Perovic says: “Belgrade is very safe city like anywhere else in normal parts of the world, maybe even more so. The situation in Serbia is normal and the economy is similar to that of Czech Republic or Hungary or other similar European countries. It is not as developed as the USA or Western Europe, but it is quite a normal country. We grew up with American movies and music so our people are always sympathetic towards Americans. Americans are MUCH safer in Belgrade then in the USA. See similar questions...

On the whole, no! We do occasionally get some stingers in the water, but they generally only stay around for a week or two. A wet suit is your best bet against getting stung. See similar questions...

The Channel is too cold and dirty for sharks. On the other hand, the channel is replete with jellyfish. The stings are not fatal but are very painful. Usually this happens as I am taking a stroke and what feels like three or four electrified barbed wires are being dragged across my skin- jellyfish tentacles. The skin usually burns for five minutes and then goes numb. Impressive scars then surface the next day. No channel swimmer is complete without his or her own collection! See similar questions...

The laser is dangerous if you look at it directly. However full laser safety precautions are taken during the operation. Everyone in the operating theatre has to wear special glasses during the laser phase of the procedure to be sure that there is no risk. See similar questions...

This is less of a problem than it used to be, especially on the Camino Francés, where the local dogs are by now entirely used to seeing pilgrims pass. But in France generally, and on the other Spanish routes, where dogs are generally kept to protect farms and flocks, it is as well to be wary. See similar questions...
