Relating to or belonging to an antenna or antennae, especially the sensory appendages of insects and crustaceans.
From 'antenna' (from Latin, originally meaning 'yardarm of a ship', then applied to insect appendages). The adjective form adds '-al' to create the technical descriptor.
Insects taste with their antennas, not their mouths—when a fly lands on your food and wiggles those little hairs, it's actually taking complex chemical samples through antennal sensory organs.
