A cold-water shrimp’s antennae are longer than its entire body. It looks absurd — until you realise where it lives.
Deep in dark Atlantic water, eyes barely work. So the shrimp “sees” another way: short antennae that smell chemicals in the water, and long ones that feel currents, vibrations and objects in the dark. It maps its whole world by smell and touch, almost without light.
Those long antennae aren’t whiskers. They’re its eyes where eyes don’t work.
