Squid labeled

What I found interesting about the squid is that they have an inner shell and we used it like a pen we put it into the ink sack amd wrote on paper.

The gills were also pretty neat to see when you put them in water you they were fanned out.

How do they fit in the world?
They serve  for biological research.

Some current investigation are based on the observation that snails and other mollsuk.
