Which unusual biological trick do some deep-ocean creatures use to escape predators in total darkness?
Correct
Certain species like the deep-sea squid or polychaete worms have a party trick called autotomy, where they release glowing bits of themselves to distract a hungry predator while they make a stealthy exit. The idea of heat mimicry is off the table because deep-sea animals are cold-blooded and generally blend in with the ambient temperature anyway. Exploding ink is a bit too loud for the shy creatures of the abyss, as ink clouds work better for visual cover in shallow waters. Sonic blasts sound like a cool sci-fi movie effect, but these critters are built for silent survival rather than acoustic warfare.
