Neptune’s mask.
Depending on interpretation, this view of the ctenophore Ocyropsis maculata looks like either an ancient Greek helmet or a clamshell bucket for earth-moving machines. This large (to 6”) predator uses its broad lobes to catch small crustaceans, rolling them up like a baseball glove catching a ball. It also uses them to swim rapidly away from trouble.
