The video shows a crab partially buried in sand. The crab is using its claws to dig and push sand, creating a small mound around it. As the crab continues to dig, more of its body becomes submerged in the sand, with only its head and part of its claws remaining visible above the surface. The background consists of fine, light-colored sand.
A crab is seen on a sandy beach, positioned near a small mound of sand. The crab begins to move towards the hole in the sand, gradually making its way closer. As it continues to move, it lowers its body into the hole, with its claws and legs still visible above the sand. The crab's body continues to descend into the hole, with only its eyes and part of its back still visible. Finally, the crab is almost completely inside the hole, with just a small part of its body still exposed.
