What other way would you want?

Challenged in September 2010 to come up with interesting facts every day by one of my work colleagues, I've since entertained him and those near his desk with bits of information dredged from my brain. Some of my audience went on holiday and still wanted the facts so I started posting here, every day I do one of them, usually Monday through Friday, and the occasional post on the weekend. I post these facts here almost every day and you will find two posts on some days to make any missing days.

Today’s interesting fact has to do with the Horseshoe Crab.

The Horseshoe crab is considered a living fossil. Fossils that looks almost exactly like the Horseshoe crab show that an animal with the same body and structure first appeared about 450 million years ago and has hardly changed in all that time, which is far longer than most species of plants or animals, including humans can ever hope to exist.

The Horshoe crabs blood is blue, because it is based around the copper atom instead of an iron atom.

Today’s interesting fact has to do with the Beaver and it's teeth.

Beavers teeth are strong and grow continuously throughout its life.

Otherwise they would be worn down from all the chewing of wood.

Their incisors are orange, because they have large amounts of iron in their enamel, to make them harder and less likely to wear down.
