Hydrothermal vents: food webs that do not start with sunlight

A 5-beat faceless video outline for “Hydrothermal vents: food webs that do not start with sunlight” in the Ocean and deep-sea life niche, derived from caption timing of 2 reference videos.

Angles

• Cold-open on the concrete hook from the primary reference — Natural World Facts leads with a scene, not a definition dump
• Make the mechanism explicit with one visual beat: two main examples of such environments are hydrothermal vents, and cold seeps. The former …
• Contrast or scale-up using the second reference (The Octopus Lady): of both archaea and bacteria, are able to tolerate fluids as hot as 122°C. Here, they carr…
• Close on what the viewer can check themselves; original narration only — do not copy reference wording

Beat-by-beat structure

1. Hook (0:00–0:30): open on the puzzle of 'Hydrothermal vents' in one image.
2. Setup (0:30–2:00): define the key terms in plain words; borrow structure from Natural World Facts, not lines.
3. Mechanism (2:00–5:00): walk the cause-and-effect with one diagram; cite the evidence beat (two main examples of such environments are hydrothermal vents, and col…).
4. Contrast (5:00–7:00): show the common myth or the second case from The Octopus Lady.
5. Recap card: three takeaways + one 'check this yourself' action. Original narration only.
