These tiny 1/4 to 1/2 inch translucent long-armed shrimps, Cuapetes grandis are quite extraordinary when seen more closely. One particular shrimp is carrying eggs.
I used an Olympus TG6 with the Underwater Microscope setting with the flash at 1/13 power. At full flash, the details would be lost. The flash highlighted the reflective details of the shrimps that would not be visible under normal daylight.
