The video features a single crayfish with a blue and white body and orange spots on its claws. It is seen walking on a gravel-covered floor of an aquarium, moving towards a rock structure. The crayfish has long antennae and its tail is visible as it moves. The rock structure appears to be a cave or shelter for the crayfish. The lighting in the aquarium casts a reflection on the glass, creating a shimmering effect.
