Remember our weird story about fish pedicures? Well it seems that the ocean has even more to offer from a beauty perspective.

British scientists have produced a nail hardening product using the shells of crabs. Apparently the crab uses a substance called Chitosan to build and repair its shell.

A thin film of the Nail it! laquer helps strengthen and stabilise nail structure and protect against damage caused by physical or chemical agents.

If you want to try some of this 'crabulous' nail varnish, head to this site - it costs £14.95!

Here are five more fantastic fingernail facts too:

  • Your fingernails grow at a rate of about half a millimetre a week and sometimes more. If you lived to be 77 years old and never cut your nails, they would be at least two metres in length!
  • Fingernails grow faster than toenails, a new fingernail will take up to six months to re-grow completely, a toenail up to a year
  • How do you spot a guitarist in the crowd? They will usually have longer nails on one hand than the other to help pluck the strings.
  • Fingernails grow faster in the daytime than at night time
  • Fingernails are much more porous than the skin. This is why your nails go soft when you’ve had a bath
