As the editorial staff of the Cosmos Magazine wrote and I quote:
“For as long as artistic expression has existed, it has benefited from interplay with scientific principles – be it experimentation with new materials or the discovery of techniques to render different perspectives. Likewise, art has long contributed to the work and communication of science”
The 2nd mysis is characterized by a number of structural changes on the setal and spine development on the antennae, maxilla, maxilliped, and uropods including the disappearance of the exopod in the first maxilla.
But to distinguish this stage, hatchery technicians will look only for the appearance of the CURVED uniramous PLEOPODS in the form letter “J” on the first five abdominal segments.
Because in the 1st mysis the pleopods are just rudimentary buds appearing as bulging structures on the ventral surface of the first five abdominal segments.
Come to think about it, if you will analyze, If the rudimentary abdominal buds in Mysis -1 is destined to become the pleopods in Mysis - 2, the rudimentary abdominal buds in Zoea - 2 will become the rudimentary pereopods in Zoea - 3
For those who might be interested, here is the full manuscript of the pioneering work of HIROSHI KITANI on the larval development of Penaeus vannamei reared in the laboratory.

In honor of HIROSHI KITANI... that his name may be remembered, and not my name.
