Replying to: The world's largest amphibian is the giant salamander. It can grow up to 5 ft. in length.

Actually, the largest amphibian can grow up to six feet. It is the Chinese giant salamander.

Another fact on amphibians: One of the smallest frogs in the world has the largest tadpole, it grows backwards!

Astatine is probably the rarest naturally occuring element with the whole Earth containing only about one ounce or 25g of this element!

Fluorine is the most electrogegative element known with an electronegativity of 4 and will forn compounds with just about every element including some of the noble gases!

Nitroglycerin (glyceryl trinitrate) is used to treat angina pains!

Flea's can jump 130 times higher than their own height. In human terms this is equal to a 6ft. person jumping 780 ft. into the air.

this is a false analogy.

Actually, not entirely, as it highlights one of the most important principles in biology, namely geometric scaling relations. If you shrink an animal to half it's normal length, all surface areas (muscle cross section, skin area, etc) will be 1/4 and all volumes (mass) with be 1/8th. This means, gram-for-gram, an half-sized animal has twice as much muscle power.

So technically, it's an accurate analogy, and merely illustrates the vast difference a bit of scaling can make in proportional capabilities.

Thats what I meant, Mokele. A flea grown to human sizes would not be able to jump that high.

That's roughly what is estimated for Francium.

The praying mantis is the only insect that can turn its head sidways like humans.

I thought it was man-made? Oh well :-)

Water is unusual in that its boilling and melting points are much higher than other simmilar Hydrogen based compounds.

Water is the only compound known to be less dense as a solid then a liquid.

The only mammals to shed saltwater tears are aquatic mammals and humans.

anti-matter is the most expensive substance on earth, costing (at low estimate) $25 billion / gram.

[RyanJ]

Water is one of only a few substances that expand when they freeze.

Hydrogen is the most abundant eleemnt sin the universe, constituting almost 90% os all the atoms in the universe!

Helium in its liquid state has a feature called superfluidity, that means it experiences no friction and is able to climb out of containers! It does this untill it meets its own "level".

Neon and Helium are the only two elements with no compounds what so ever although ionic compounds such as and have been formed!

In an airtight room, you will die from breathing in your own toxic carbon dioxide, not from lack of oxygen.

[rakuenso]

that's why I always bring a plant whenever I go into a room :D

Carbonic acid?

The most powerful explosive explosive known is as a Tritruim fussion bomb and is one of the most descricuve devices created by man!

A form of thermite can be used to extract pure Uranium! It is sometimes called the Ames process.

This is the African Paradoxical frog. It spends most of life cycle as a tadpole and only matures to reproduce.

During hibernation, a hedgehog's body temperature drops to about 5.5 degrees C. Its heart beats between 2 and 6 times a minute and it only takes from 1-3 breaths per minute.

However the mammal with the lowest body temperature during hiberantion is the hamster with a body temperature of 3.5 degrees C.

More specifically, it is the methanogenic Archaea inside the termites that produce the methane.
