As a subject matter expert in the field of biology with a focus on arthropods, I can provide you with an informed answer regarding the sensory capabilities of spiders.

Spiders primarily rely on their sense of vision and touch to navigate their environment. They do not have ears as humans do, but they can detect vibrations through specialized sensory organs called hair sensilla. These hairs are sensitive to air movements and vibrations, which allows spiders to sense the presence of potential prey or threats.

Spiders' eyes are quite different from human eyes. They typically have multiple simple eyes, known as ocelli, which give them a wide field of view. However, their vision is not as sharp as humans'. The number of eyes can vary from species to species, with some having as few as two and others as many as eight. The quality of their vision also varies; while they can't see in great detail, they can detect movement and the general shape of objects.

In summary, spiders do not "hear" in the traditional sense but can sense vibrations. They can also see, but their vision is more focused on detecting movement rather than detailed imagery.

Spiders, in fact, do taste, and also smell, through special sensory organs on their legs, as well as on their pedipalps. And they hear �C or, more specifically, they sense vibrations �C through hairs and tiny slits distributed over much of their body. A spider's sensitivity to vibrations is finely tuned.read more >>
