Sea turtle over a coral reef, underwater glide prompt

An underwater wildlife clip: a green sea turtle glides over a shallow reef while sunlight ripples over its shell and a few silver fish move out of its way. Turtles are a kind subject for AI video because they move slowly and evenly, so there are no sudden poses for the model to get wrong. Use it for ocean and travel reels, a diving school page, or calm b-roll behind narration about the sea.

Seedance 2.0

A green sea turtle swims slowly over a shallow coral reef in clear turquoise water. Motion: the turtle glides with slow strokes of its front flippers, small silver fish part around it, sunlight ripples across the coral. Camera: underwater, steady tracking shot from the side and slightly below the turtle, moving with it. Setting and light: bright sun from above, dancing caustic light patterns on the shell and the sand, blue water fading to deep blue in the distance. Style: wildlife documentary, clean natural colours, high detail on the shell and skin. Sound: muffled underwater ambience, soft bubbles. Duration: 5 seconds.

What each part of the prompt does

Slow front flippers: Describing the stroke as slow and driven by the front flippers matches how turtles really swim and keeps the limbs from flapping like wings.
Track alongside: Moving with the turtle keeps it the same size in frame for the whole clip while the reef passes underneath, which shows travel without losing the subject.
Caustic light: The rippling patterns that sunlight casts through waves are the detail that says shallow water. Naming them makes the scene look wet rather than tinted blue.
A few small fish: A small school moving aside gives the reef life and shows scale. Asking for many species at once usually crowds the frame.

Variations to try

Same idea, one thing changed. These have no clip yet.

Swimming toward the camera
A green sea turtle swims slowly toward the camera over a shallow coral reef in clear turquoise water. Motion: slow strokes of the front flippers, the turtle rises a little and passes just above the lens. Camera: underwater, still, low on the sand looking up. Setting and light: bright sun from above, sunbeams in the water, caustic light on the sand. Style: wildlife documentary, natural colours. Sound: muffled underwater ambience. Duration: 5 seconds.
Vertical surface view
A green sea turtle swims up to the surface of clear turquoise water above a pale sandy reef. Motion: the turtle rises slowly, its head breaks the surface for a breath, then it dives again. Camera: half above and half below the waterline, steady. Setting and light: bright tropical sun, sparkling surface, blue sky above the waterline. Style: wildlife documentary, crisp detail. Sound: a soft splash, muffled water below. Duration: 5 seconds, vertical 9:16.

If the result isn't right

Keep the water clear and shallow. Deep or murky water makes the model darken the whole frame and lose the shell pattern.
If the turtle grows extra limbs, add "four flippers, the front pair larger" to the motion line.
For a calmer first frame, start the turtle near the left edge so it swims into open water ahead of it.
