'Fish'
This drawing is actually a physical impossibility! There are six fish or parts
of fish in the water
They could not actually live in the same water - two
of them are based on fish which live in extreme depths of water and in total darkness
and therefore would explode if they were in shallow water
or in reverse the
four other fish would implode if they were so far down!!
The fish approximately
in the four corners of the drawing are the shallow water fish
