Do Spiders have noses?

Question

my 2 year old daughter would like to know.

Answer 1

I not sure, but, sometimes I play with these fuzzy little spiders as they seem to enjoy it. I poke at them with my finger and they run and then jump on my finger and look around as if they playing. As I look at them they seem to take on a personality that seems to have a face, including a nose. ;-)

Answer 2

No, spiders have no noses if by nose you mean
some sort of facial projection that they breathe
through. Their air intake is through openings on
the under side of their abdomen (book lungs or
tracheae), and their senses of smell or taste, if
they have them (most seem unable to smell in
the way we do, at least they show no reaction to
odors we have no trouble detecting), are in various
parts of their bodies. They do have taste senses in the mouth region.

Answer 3

I don't see a nose on the anatomy of the spider.

SPIDER ANATOMY

All spiders have 8 legs, 2 body parts (cephalothorax and abdomen), fang-like "chelicerae," and antenna-like "pedipalps." Click on the terms below to learn more about each body part.










CEPHALOTHORAX


The cephalothorax is the first of 2 body parts on a spider. It is a combination of the head and thorax, and on it are found the legs, eyes, pedipalps, chelicerae, and other mouthparts. The cephalothorax and abdomen are connected by a thin stalk called the "pedicel."


CHELICERAE


The chelicerae are a spider's jaws. They are located on the very front of a spider's cephalothorax. Every spider has a pair of chelicerae, and they are tipped with venomous fangs. Chelicerae are filled with muscles, and are used to hold prey while the spider injects venom.

Spiders do not actually drink fluid through their fangs. Located behind the chelicerae are other small mouthparts, including the labium and labrum. Along with the chelicerae, these mouthparts work together to direct food into the spider's mouth, which is hidden behind the chelicerae and other mouthparts.

Some spiders, like cobweb spiders, are only able to consume fluids, but most spiders are able to eat solid food after it has been shredded and mashed by the chelicerae.

In most spiders, the chelicerae are like scissors: they move from side to side. But in some primitive spiders, such as tarantulas, the chelicerae move up and down, like 2 fingers side-by-side. The Iziko Online Museum has an excellent diagram that illustrates these two types of chelicerae.

All of the other arachnid groups, including Scorpions, Mites, and Harvestmen, have chelicerae as well, but spiders are the only arachnids with venomous chelicerae.


PEDIPALPS


Like the chelicerae, a spider's pedipalps are part of its mouth, and are located just between the chelicerae and first pair of legs on the cephalothoarx. Pedipalps are jointed, and look somewhat like small legs. They are not used like legs, though. Instead, they are more like antennae: pedipalps help the spider sense objects that it encounters. Some spiders are also able to use their pedipalps to shape their webs and to aid in prey capture.


Pedipalps are used by male spiders to transfer sprem to female spiders. In fact, you can usually distinguish a male spider from a female because of the male's enlarged pedipalps.

All arachnids have pedipalps, but they often look quite different than spider pedipalps. In Scorpions, for instance, the large pincers are actually modified pedipalps.


EYES


A spider's eyes are located on the cephalothorax. Most spiders have 6 or 8 eyes. Spider eyes are considered "simple": they do not have multiple lenses and facets as do the compound eyes found on some insects. Although some spiders can only see the difference between light and shadow, others, especially Jumping Spiders, are believed to have excellent eyesight.


LEGS





Like all arachnids, spiders have 8 legs, all of which are attached to the cephalothorax. Each leg is made up of 7 segments (shown above). Attached to the cephalothorax is the coxa, followed by the trochanter, femur, patella, tibia, metatarsus, and tarsus. The tarsus is tipped with 2 or 3 claws, depending on the spider family.

ABDOMEN


The spider's abdomen contains many important internal organs, such as the digestive tract, reproductive organs, and lungs. Tipping the abdomen are the spinneretts.


SPINNERETS


A spider produces silk through tiny pores in its spinnerets. Most spiders have 6 spinnerets.

Answer 4

They dont have noses,because I dont think they can smell.They breath using book lungs(respiratory organs used by spiders,scorpions and other relatives),a tracheal system,or both.Some "advanced spiders" breath using spiracles.

Answer 5

naw they dont.they receive air from another place.idk

Answer 6

no
