Final answer:
Animal whiskers serve a sensory function, are highly sensitive to touch, and help animals navigate their environment. They are not typically described as being in a square lattice formation.
Step-by-step explanation:
Animal whiskers, such as those of cats, serve a sensory function that helps these animals navigate their environment. The presence of whiskers in a square lattice formation isn't typically noted in biological literature, as animal whiskers are not arranged geometrically but naturally according to the anatomy of the animal. The whiskers of animals are highly sensitive to touch and can detect changes in air currents, enabling animals to sense objects and movements around them, even in the dark. This tactile sensing ability is crucial for animals like cats and moles when hunting or moving through tight spaces. A mole, for example, uses its star-shaped nose and large front claws to navigate and find food underground where it is dark.
