What if blue whales began orbiting one another like moons

In the deep open ocean, a pod of enormous blue whales lift free and begin orbiting one another like a miniature system of moons. Stable paths, changing shadows, drifting debris, and layered depth make the orbital motion believable. Sun shafts, bubbles, plankton, and distant divers establish their scale. Join the orbit of the nearest form and reveal the complete system turning around its center.
