[00:00:00]In the warm waters, the bobtail squid hosts a living lantern, Vibrio fischeri, inside a specialized light organ.

[00:00:07]The bacteria glow only at night, providing counter-illumination that hides the squid from predators and helps ambush prey.

[00:00:15]In return, the squid shelters the bacteria and shares nutrients, maintaining a mutual bond that scientists compare to a tiny solar engine.

[00:00:24]This luminous partnership underscores how life adapts by sharing resources, a theme that resonates with human teamwork and innovation.

[00:00:32]By watching the glow, viewers see biology through storytelling, turning an underwater microcosm into a bright lesson in cooperation.
