Spiders

The tan and black spider with horns on its back is the Arrow-shaped Micrathena. These spiders spin their webs in spirals and hang in the center of the web, often mistaken for a piece of wood or leaf.

It varies. Typically insects (which are arthropods) have 6, although it can vary depending on species. Because the name "arthropod" refers to any organisms with exoskeletons, there is no exact number of legs that an arthropod may possess. Insects in general possess 6 limbs, while arachnids such as spiders have 8. Crustaceans like lobsters or crabs may support 10 or more. Still, some species in the subphylum myriapoda such as millipedes or centipedes may contain at least 9 pairs of legs. The leggiest specie of arthropod, Illacme plenipes, which is a Californian millipede, has been recorded for having 750 legs.

An arachnid has 2 body sections and 8 legs. An example is a spider or scorpion.

Most spiders typically live for about a year, although up to five to six months of this may well be spent in the egg stage.

However, there are some tarantulas that can live for as many as twenty years, and even one species has been known to survive over thirty years in captivity.

Then there are some tropical jumping spiders that only live for three months or less.

Spiders can be found in various habitats worldwide, including forests, grasslands, deserts, and even human dwellings. They typically prefer dark, sheltered places where they can build their webs to catch prey.

They don't have mouths so there fangs sink into their pray releasing a paralysis poison into the body. Then later when it wants to eat it it releases another poison into its prey which liquefies its organs which are then sucked up through fangs and into the stomach.

Black widow spider venom affects the nervous system. Because the bite itself is relatively mild, some people may not even realize immediately that they were bitten. The venom causes pain in the lymph nodes. Other symptoms of a severe bite include dizziness, blurred vision, nausea, elevated blood pressure, sweating, tremors, breathing difficulty and increased white blood cell counts. The wound may appear as a bluish red spot, surrounded by a whitish area. Both male and female spiders bite, but adult females produce the most severe bites. A physician should be contacted immediately following a suspected bite. An antivenin serum is available through a physician, but it must be administered soon as possible after the bite occurs. When this happens, fatalities are rare and recovery is usually quick and complete. --------------------- Long story short: The venom attacks your nerves, which could lead to becoming comatose, seizure, & paralysis.

Spiders do not have a backbone because they belong to a group of animals called arachnids, which have an exoskeleton instead of an internal skeleton. This exoskeleton provides support and protection for their bodies. Spiders are able to move and function effectively without a backbone due to this exoskeleton.

The exoskeleton is made of several layers of cuticle, a composite material containing various proteins and chitin, a long-chain polysaccharide (sugar). The chitin and protein molecules are arranged in long chains, in successive layers, like the grain in plywood. This structure makes cuticle extremely strong, as well as highly effective at keeping the spider from drying out, but the material does have one serious drawback. While it's flexible enough for movement, it can't expand like human bones and tissue -- in other words, it can't grow. In order to increase its size, the spider has to form a new, larger cuticle exoskeleton and shed its old one (this is called molting). Molting occurs frequently when a spider is young, and some spiders may continue to molt throughout their life. At the appropriate time, hormones tell the spider's body to absorb some of the lower cuticle layer in the exoskeleton and begin secreting cuticle material to form the new exoskeleton. The new exoskeleton is typically folded to some extent, so it can expand once the spider sheds the older one. The spider also secretes a molting fluid between the old exoskeleton and the new one. Once the new exoskeleton is finished, the spider absorbs the molting fluid. This creates a gap between the two exoskeletons, which makes it easier to separate them.

Yes, black widows can be found in Florida. They are native to the state and can be found in various habitats including forests, gardens, and homes. It's important to be cautious around areas where they may be present.

There are a number of creatures that are called 'Daddy Long Legs'. The most common one is the spider that lives in homes, often on the ceiling, with a very small body ranging from 2 - 10 mm. The legs can be up to 30 mm.

The two that are less common are the Harvestmen spider with a 7mm body and legs that are 14 cm long, and the Cranefly, an insect, can grow up to 60mm.

Spiders have 8 legs.

1. Happy face spiders, scientifically known as Theridion grallator, are small spiders found in Hawaii.
2. They are known for their distinctive yellow markings on their abdomens that resemble a smiley face.
3. Happy face spiders are not dangerous to humans and play a role in controlling insect populations in their ecosystem.

The life cycle of a brown recluse spider starts with an egg sac laid by a mature female. The eggs hatch into spiderlings, which grow through several stages before reaching maturity in about one year. The adult brown recluse can live for up to two to three years.

Spiders have eight legs while insects have six. Spiders have two body segments (cephalothorax and abdomen) compared to insects which have three body segments (head, thorax, and abdomen). Additionally, spiders do not have antennae like most insects do.

The spider with a target-like pattern on its back is commonly known as the arrowhead orb weaver spider (Verrucosa arenata). This species is known for its unique and distinct marking, resembling a target or bullseye.

The spider in question has got me baffled. I've looked on google for hours and no answers for me. Hes a light brown spider. I found him in my utility room on the wall. I live in tallahassee, Fl. His legs are all pretty close to the same length. All four on both side point to either to the side or to the front. He doesnt have legs that extended behind his abdomen when walking or resting. His legs have black dots that go down them. They kinda look like stripes except they are only on the top half of his leg not underneath. He has two small legs in the front that are overtop his fangs. Hes slightly larger than a quarter. His head is darker than his body, its a dark brown with a white stripe or border where his head meats the abdomen. On his abdomen he has a particualr marking. On the the upperhalf of the topside of his abdomen he has what looks kinda like a sword pointing down? Its two little black dots at the point where head and abdomen meet with a line that stretches down about half way it his 'butt'. The after that line ends there are two larger black dots one on the left side and on one the right side of the lower half of his abdomen. On his belly there is a marking that looks similar to a rough pencil sketch of a vagina. Along with two white dots at the very top of his belly. I thought maybe a wolf spider but I dont think so, Hobo, Huntsman, Brown Recluse...they all kinda look like it but not enough to make me a believer. I need help please.

The spiders you are referring to are black widows, known for their distinctive black coloration with a red hourglass shape on their underside. They are venomous and found in various parts of the world.

Spiders do not have hairs, they have bristles.

The bristles are actually touch-sensitive receptors and they allow the spider to sense minute movements in air flow, or the slightest vibrational movement of their web when an insect becomes entrapped.

The Black Widow spider got its name because the female eats her mate following mating.

Though this does not always happen, people believed it did and therefore gave the spider its title.

The female usually kills the male after mating.

The Komodo dragon. The bacteria in its saliva is so toxic kills whatever it has bitten (if left untreated) within a week.

The Brown Recluse spider's bite can cause necrosis, but fortunately this is rare.

Hippos are also have deadly bites and can sever limbs.

grasshopper : trachea

crayfish: gills

Two poisonous spiders found in Australia are the Redback spider (Latrodectus hasseltii) and the Funnel-web spider (Atrax and Hadronyche species). Both spiders can deliver a potentially dangerous venomous bite to humans.

Brown recluse spiders are not known for their speed; they move slowly compared to some other spider species. They typically rely on their camouflage and stealth to catch prey rather than chasing it down.
