Sea Emperor Egg Casing

Shell Composition: The shell casing is formed from thick layers of carbon-composite, suggesting an extensive gestation period. This leviathan species may give birth just once per century, perhaps just once in their lifetimes.

Shell Casing Incisions: Precise incisions suggest a laser-based tool was used to cut open the egg casing and forcibly remove the fetus inside, prior to full gestation.

Analysis: - Time-pressure to develop a bacterial vaccine may have driven the alien researchers to cut open this egg and remove the fetus for study - It is also possible that, removed from its parent and natural habitat, some vital condition for the infant to hatch naturally was not met
