Unusual (possibly healed) damage to the left eye area. This was in the surf but didn't seem to be moving and I presume it was dead (countless other dead were high up the beach).

No sé porqué estan de color rosa, todas estan muertas y no son exuvias
La artemia suele agarrar colores rojos/rosas al consumir halobacterias (las mismas que le dan el color rosa a las coloradas)
Quizás estas larvas consumieron artemias con los pigmentos rosas?

Was wondering what the green X painted on him/her could be? I know they collect and return horseshoe crabs for drawing blood around here so I thought maybe it meant it already had blood drawn?
