Guarda Armado vs Criatura Marinha Bioluminescente

Single continuous handheld of an armed guard standing on the deck of a small ship, looking over a dark metal railing down at the choppy ocean. Heavy overcast gray daytime, flat cold diffused light, misty atmosphere, realistic B-movie horror style exactly like the provided reference images. A large translucent bioluminescent half-jellyfish half-squid creature with a pale bulbous mantle and thick dangling tentacles bounces energetically across the dark water surface 15-20 meters away, splashing and hopping like a living ball. The guard is breathing heavily and speaking urgently into his radio in panicked tones about the creature moving on the water, asking for orders and whether he should engage, reacting in pure shock every time it suddenly disappears. He fires his rifle multiple times. Each shot causes the creature to instantly vanish in a splash and reappear a few meters away, still bouncing playfully. A tense voice on the radio crackles back instructing him to take it out. This cycle repeats 2-3 times with realistic water physics and shaky camera. At around the 13-second mark the creature suddenly stops bouncing, hovers for a split second, then rockets away at blinding super speed directly into the foggy horizon like The Flash, disappearing completely. Cinematic tension, photorealistic, high detail, subtle film grain. Natural sounds.
