Arthropods

In taxonomy "arthropod" is a phylum or major division on a hierarchical tree. The 'genus' taxon is a much lower (or more detailed) division, describing fewer groups of organisms. You might say that phylum arthropoda 'contains' many genera.

There are variations depending on the species; not all arthropods have mouthparts used to chew; some have sucking mouthparts, depending on life cycle there may be none. For those that do have jaw-like functions, you might see:

Mandibles: For shearing, piercing, and processing food.

Labra (singular labrum): Functions as an "upper-lip."

Maxillae: Ancestral biramous (two-branch) appendages for manipulating and tasting food. The slender walking-limb like part is called a maxillary palp (in aquatic crustaceans, the mandible also bears a palp.) Ancestrally, first and second maxillae were present.

Maxillae can be fused or modified into derived structures. In some insects the second maxillae are fused to form a labium (lower lip).

The soil beneath your feet is full of life.Bugs that are also known as arthropods.They make their habitat in the soil.The way they got their name is from their jointed legs also called arthros these bugs are invertebrates.It means they don't have a backbone but instead of a backbone they have a external covering called a exoskeleton.The arthropods range in their size from several inches to microscopic in the length.And sciencets also included insects such as spring talls, beetles, ants, crustaceans also known as sow bug ,spiders also known as arachnids,mites,myriapods also known as centipedes,millipedes,and scorpions.Almost every soil is a home to a lot of different arthropod species.Soil like corn or soybeans grown in it has several bugs in a square mile.The bugs can be grouped as in shredders,predators,herbivores,also fungal-feeders arthropods eat fungi,worms,or other bugs.Dead-plant shredders and root-feeders and dead-plant shredders feed the bugs aerate and mix the soil.

no they don't have kidneys

A live anthropod would be any non-dead human. Anthropods (bipedal humans or humanoids) should not be confused with arthropods; Arthropods are characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages.

Some arthropods are no longer living (extinct), like trilobites and the class Marrellomorpha.

A carnivore is any animal that eats meat, e.g a dog is a carnivore, a cat is a carnivore, a human is a carnivore.

A mini beast is the general name for insects, bugs and aracnids (spiders)

Likely the intent is "classify" (to clarify is to make clear, or to explain). Arthropda fall under Metazoa (Animalia); Eumetazoa; Bilateria; Protostomia; Ecdysozoa; Panarthropoda. Arthropods are characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages.

spiders and stuff

A lobster is not a mollusc - molluscs are slugs and snails and the like.Lobsters are classified in the phylum Arthropoda, along with the other crustaceans, insects, arachnids and centi/millipedes.

they already know how to fly(learned behavior) but there is nothing inheritatd

(by the way this is Karina Shtyba)

yes

Not all arthropods have chewing mouthparts but for those that do:

Mandibles: For shearing, piercing, and processing food.

Labra (singular labrum): Functions as an "upper-lip."

Maxillae: Ancestral biramous (two part) appendages for manipulating and tasting food. Maxillae can be fused or modified into derived structures. In some insects the second maxillae are fused to form a lower lip (labrum).

no

No, myriapods are a subphylum of arthrpods, and include the centipedes, millipedes and their ilk. It would be better to say arthropoda includes all myriapods.

Gastropods are separate, in a different phylum - Mollusca (the molluscs), brachiopods likewise have their own phylum.

In taxonomy, 'class' has a specific denotation. Arthropoda (the arthropods) is a major division called a phylum. It falls under the animal kingdom (Animalia, or Metazoa) and also falls under other classifications such as Eukaryota, Opisthokonta, Eumetazoa, Bilateria, Protostomia, Ecdysozoa and Panarthropoda.

Below phylum are the subphyla and the classes, of which arthropoda has several, including the Malacostraca class (lobsters, shrimp, etc), the Insecta class (insects), and others.

The current system will classify organisms by Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species. Scientific names include the genus and species of the organism (like homo sapien for humans).

The exoskeleton

Yes, technically, being double jointed is real, but the correct name for it is hypermobility or hyperlaxity, which is what doctors and other medical people will refer to it as. Look those words up and you can discover a little more about being hypermobile. I am double jointed, and can do lots of weird things from my shoulders to my fingers, so it does make me angry to see somebody who says being double jointed isn't real. It is, but they may call it something else. It's all the same thing.

In taxonomy under phylum arthropoda are subphyla Chelicerata, Myriapoda, Crustacea, and Hexapoda. There is also an extinct class Marrellomorpha and an the extinct Trilobite subphylum. The chelicerata, like spiders, scorpions, mites, etc., get their name from having appendages appear before the mouth; myriapods like centipedes and millipedes characterized by a high count of body segments and legs; crustaceans like crabs, shrimp, woodlice characterized by their biramous (two-part) limbs and a nauplius larval form; hexapoda named for their consolidated thorax with only three pairs of legs.

Arthropods don't actually use red blood cells, nor hemoglobin; the arthropods that use oxygen-carrying molecules in their circulatory fluid (hemolymph) use hemocyanin, a copper-based protein rather than iron-based like hemoglobin. It's also not bound to cells but drifts around in the fluid. When oxygenated it turns a bluish color.

Note that the oxygenation strategy for most (but not all) arthropods is to get oxygen directly from the air, through openings in their segments (spiracles) that connect to a trachea and to smaller tubules connected directly to tissues, thus bypassing a liquid circulatory system.

Only some arthropods have a cephalothorax, like for example the lobster. Other arthropods have functionally separate (or non-fused) head and thorax, like many insects.
