do spiders have ears...?

Question

what i mean is can they detect sound through the air...or are they only capable of picking up vibrations.

same goes for all other insects...can any of them hear?

Answer 1

Not as we know them. Arachnids are exquisitely sensitive to VLF vibrations via their legs and I would speculate that the different hair lengths play a similar part as in the cochlea of vertebrates. Scorpions can triangulate the position of insect prey across a meter of soft sand using the vibrations picked up by their legs, much as we do when turning our heads towards a sound. I would imagine a smart spider could detect the position of a trapped fly in its web, purely by 'polling' the various strands of its web in the same way computer software detects a keypress.
As for insects, many use mating calls and many are susceptible to UHF sounds as a repellent

Answer 2

Spiders usually have eight eyes in various arrangements, a fact which is used to aid in taxonomically classifying different species. Most species of the Haplogynae have six eyes, although some have eight (Plectreuridae), four (eg., Tetrablemma) or even two (most Caponiidae) eyes. Sometimes one pair of eyes is better developed than the rest, or even, in some cave species, there are no eyes at all. Several families of hunting spiders, such as jumping spiders and wolf spiders, have fair to excellent vision. The main pair of eyes in jumping spiders even see in color.

Net-casting spiders have enormous, compound lenses that give a wide field of view and gather available light very efficiently.

However, most spiders that lurk on flowers, webs, and other fixed locations waiting for prey tend to have very poor eyesight; instead they possess an extreme sensitivity to vibrations, which aids in prey capture. Vibration sensitive spiders can sense vibrations from such various mediums as the water surface, the soil or their silk threads. Also changes in the air pressure can be detected in the search for prey.

It is almost impossible to live with tinnitus but you don't have to. If you are hearing the noises, whether all the time or intermittently, you must seek treatment immediately. But sadly, conventional treatments only treat the symptoms of tinnitus and may provide temporary relief at best.

The only way you could ever get rid of your tinnitus for good is by following the holistic approach to healing. By using a multidimensional treatment for tinnitus, we are tackling all tinnitus causative factors and eliminating these triggering elements from the root. This is the only path for permanent freedom from tinnitus.

Answer 4

No, they do not.

Just humans have hairs on the inside of their head, spiders have hairs on their legs called thrichobotria. They are capable of localizing the origin of a sound by interpreting the movement of the air produced by that sound.

Answer 5

Spiders...no. Just vibrations. Crickets yes. They can hear. Other insects can hear too...like Cicadas.
