Guess what this is?

Personally I would never have guessed correctly. Lets see if this image is just as surprising to you as it was to me.

Hint: 10x objective used.

i'm taking a shot in the dark here... mgso4 in polarized light? If not is it a crystal of some type?

Polarized light - yes. MgSO4 - no. Tip: It is not what you would think it is.

Is it from a living organism?

Jesus? I'm sure I can make out his face. At 10x magnification, this would indeed be a surprise.

A piece of plastic wrapping?

Yes it is from a living organism. No, it is not Jesus.

Is it from a plant, an invertebrate or a simple vertebrate?

pwnell · Post by **pwnell** » Fri Jul 19, 2013 10:39 am

Vertebrate.

Is it a fish scale?

Nope. But you are getting warmer.

Is it skin? Maybe a thin scab under crossed polars

Even closer, but no. It is the muscle tissue of Sockeye Salmon under polarized illumination. I did not think it would look like that.

Ah you shouldn't have told me

I could see something which might be bundles of muscle fibres. Btw if you look up closely into the structure of the muscle fibre you would see I- and A-bands stemming from isotropic and anisotropic which I suspect is a property in conditions of polarized lights (possibly due to the highly ordered crystaline like array or proteins).
