(Mollusk)

A small, dark-colored crab with large, protruding eyes emerges from a yellow and white seashell, slowly extending its body and eyestalks outward before retracting back into the shell. The crab remains inside the shell for the duration of the loop, with its eyes and head moving slightly. The setting is a close-up view of the crab within the shell, against a plain, light-colored background.
