Arachnids
Arachnids are members of a broad class of organisms that are very familiar to humans. The organisms in this class range from the common spiders to scorpions to ticks and mites. However different these organisms are, they all share one common characteristic, they all have eight legs. Questions and answers about the class and the organisms in it should be placed in this category.

Which characteristic would be important in classifying an animal as either an insect or an arachnid?
an important characteristic would be that arachnids only have 8 or more legs also they dont have wings. some arachnids are crad, spider ex.
The word arachnid comes from the Greek legend of a beautiful lady who dared to compare her weaving skills to the goddes Athena. Her name was called Arachna. So Athena turned her into a spider! She lived in a cave and was defeated by Hercules.
Arachnids are spiders and related animals They walk on 8 legs. Some spiders also ride the wind on a length of their silk, much like riding a mythical magic carpet.
I have been researching this question myself. According to a local vet and every internet source I can find, it is not possible for a tick to burrow under the skin. However, I actually saw otherwise.
We found a stray 5-month-old puppy who was covered in ticks. We took her to the vet and gave her Frontline. We picked well over 100 ticks off of her, alive and dead. She had lots of ticks in her armpits, but we also found some bumps. They were fairly large raised areas with a black circle in the middle. I questioned friends and family as to whether these could be ticks. I also called the vet. One of the techs told me that ticks would not be under the skin, so we just watched the areas to see what happened.
Five days later, we had gotten most of the dead ticks off of her. However, the bumps were still there and still the same. We finally decided to check them out. We squeezed the bumps, and they began to ooze a clear pus. As we kept squeezing, the black thing started to emerge. Once we could, we grabbed it with tweezers and pulled it out. It was, in fact, a dead tick. We found two others just like this.
There are other suspect areas, but we are continuing to monitor them.
I just returned from camping with the cub scouts in Virginia Beach. My son woke up Saturday morning with a new mole on his neck. When I looked closely at it, it was a tick, but only the back 1/3 was above the skin. The rest was visible as a dark area just under the skin. A nurse we were camping with looked at it and said "emergency room". We went to the hospital where it took two PA's and two nurses over half an hour to extract the tick using tweezers and hydrogen peroxide. They said the hydrogen peroxide was to make the tick back out as it would deprive him of oxygen once it started to foam. The only problem was that the tick mouth was so deeply embedded that the hydrogen peroxide couldn't get that deep. They ended up pulling it out in pieces. This was after they shot pain killer into the wound. He ended up with a tick sized wound on his neck. This was on Halloween morning and the tick was on Joey's neck near his jugular vein so this became known as the Vampire Tick Attack of North Landing Park.
Do arachnids have 2 body regions?
The body region of an arachnid is the cephalothorax. The cephalothorax is like the head and the thorax combined.
P.S. HA!! To all of you adults and teenagers out their with that question and to you who answer it with "holy squidward!" because you just got told of by a 12 year old girl.
The body region of an arachnid is called a?
The body region of an arachnid is called the gnathosoma (or capitulum
A caterpillar is not an arachnid, it is the larval stage of an insect.
What is the outer covering of arachnids?
Arthropods are protected by an outer covering of a hard protein chitin, similar in function to the protein keratin in hair, nails, hooves, beaks, claws, etc., elsewhere in the animal kingdom. Some arthropods particularly marine ones further harden it through biomineralization with calcium compounds.
Because of the rigidity of the arthropod exoskeletons, they need to periodically shed it (moult) in order to grow.
How does the brown recluse spider protect itself?
The spider gets its name because it loves to hide. To defend itself from potential predators, it bites the assaulter. If you live in a prominent area of brown recluse spiders, then you should be aware of its preferences for nutrition.
A brown recluse spider hunts for prey during the night hours. It bites its prey, leaves it for dead, and then returns later to recover the corpse. The brown recluse spider will eat anything from small insects (like grasshoppers) to other spiders. Keep your home pest-free, keep the laundry off of the floor, keep your attic and basement clean, recycle old cardboard boxes, and seal any crevices in your home. This will help you fight off any infestations from these spiders and any other insect.
What main group of animals do arachnids belong to?
Arthropods include several orders of invertebrates:
- insects
- arachnids (spiders, scorpions)
- crustaceans (shellfish, snails)
The four living subphyla are:
Chelicerata - horseshoe crabs, scorpions, spiders, mites, ticks
Myriapoda - millipedes, centipedes
Hexapoda - insects (six legs)
Crustacea - crabs, lobsters, shrimp
How is the vision of insects and arachnids different?
Most spiders have four pairs of simple eyes, usually grouped into two or three rows, an arrangement that gives them a wide field of vision. Insects have one pair of compound eyes, each made up of individual hexagonal-shaped facets and each facet has its own optic nerve. Their compound eyes allow them to see all around themselves without moving, and this ability makes them very sensitive to seeing any nearby movement.
Why do you think a diving spider surrounds itself with a bubble in the water?
water spiders are just like any other spider. they need oxygen to breathe. since their home is in the water, best thing to do is to bring the air to their home, that way they can breathe.
the way they bring the air down with them is due to special hairs on their abdomen. they catch the air and allow the spider to bring it down with them.
What is an arachnids symmetry?
Arachnids, like all arthropods, have bilateral symmetry. This means they have symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
Spiders have an exo skeleton, their "bones" are on the outside. No. they would not have a spine. although when some spiders molt, or shed their skin, and old exoskeleton. This enables them to grow.
Ants are social insects of the family Formicidaeand, along with the related families of wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the mid-Cretaceous period between 110 and 130 million years ago and diversified after the rise of flowering plants. Today, more than 12,000 species are classified with upper estimates of about 14,000 species.[3][4] They are easily identified by their elbowed antennae and a distinctive node-like structure that forms a slender waist. ( Wikipedia ).
Arachnids surprisingly,as from what I know,you may want a second opinion,actually keep their population in check by themselves,I know for a fact that the daddy long legs spider eats other spiders as well as their own kind,you also get a nasty tarantula wasp that lays its eggs in the tarantula after paralyzing it,the eggs hatch in the tarantula and they eat it inside out.Nasty....
What are the two main differences between insects and arachnics?
- insects 1 pair of antenna
- 3 pair of legs
- 3 body parts
- adults live on land
- Arachnids 4 pairs of legs
- 2 body parts
Arachnids are a species of eight legged, joint-legged invertebrate animals. The class includes spiders and many different species of scorpions.
