Fig. 5. Transverse scan of one P. cornutum female, showing five shelled
eggs. Notice the asymmetry of the eggs caused by egg overlap and compression.
Virtual calipers (dotted white lines) show the width of egg 4. Scan is focused
on one side of the animal because the animal's width exceeded that of the
transducer, as was the case in all individuals of P. cornutum.
