Having long, prominent, or widely-spread antennae or horn-like structures.
From Greek 'eury-' (wide, broad) and 'cerous' (bearing horns or antennae), describing the prominent sensory or decorative projections of certain organisms.
Insects with eurycerous antennae can detect smells from miles away because those long, branching antennae give them an enormous surface area for scent receptors!
