The breathing tube at the front which appears to connect into the suit again becomes the upper fin at the front.
Meanwhile the man's eye seems to become the alien creature's eye whole his nose becomes its mouth.

b.ii) Head of boy becomes space between the upper limbs of the right swimming creature. Man's head becomes the face of the creature on the lower half of the body.

b.iv) The original magazine page
