Arthropods

By walking, flying, swimming. Just about any method you can think of. As the largest phylum in the animal kingdom arthropods include crustaceans, Insects and arachnids.

Most walk, but certain species can swim, hop, fly and even wiggle in some larval stages. Some species of spider are even transported by the wind using silk as a parachute

Almost all arthropods have antennae, like the insects, crustaceans, millipedes, etc. The chelicerates (including arachnids like scorpions and spiders) have none, and they are also absent from a subgroup of hexapods (which contains the insects) called proturans.

Firstly, any sizeable organism be it Arthropod or otherwise would need some kind of infrastructure if it's important to that organism to maintain a consistent general body plan or morphology. Not all organisms require this; for example there are amorphous organisms like the amoeba or certain fungi; some slime molds can grow to a significant size and survive quite well with a highly generalized and nonspecific shape. In the case of those with a high degree of motility, some consistency in shape is useful. Even jellyfish with no significant skeleton, have sufficient rigidity for mobility. The important thing is, the degree of infrastructure is consistent with the habitat and behaviors to which it's adapted. In the case of arthropods, an exoskeleton is very convenient and an endoskeleton would be redundant; for vertebrates, an endoskeleton serves this role and an exoskeleton would prove cumbersome. To be sure, some vertebrates evidence similar adaptations for which an arthropod uses an exoskeleton, for example, the plating on an armadillo, the shell on a tortoise, the thick skin on large mammals, etc; yet for their mass, the thickness of an exoskeleton to provide the necessary rigidity for the purpose of the body plan in vertebrates would be impractical. The reverse can be said to be true of some arthropods; since some have muscles which anchor not to the exoskeleton but to internal cartilaginous structures which are arguably somewhat endoskeletal.

One might say, the laws of physics, particularly mass and gravity, dictate the usefulness of an exoskeleton to Arthropods given their size, role, and adaptations; the hardness of it reflecting the requirements placed upon the organism for its functionality and thus, its survival.

yes they have one heart that runs through a large part of it's body

There are snakes, mountain lions, and a variety of wild dogs. there is also a tricolor hernon

Spiders... with big fangs. O____O

Arthropods include an incredibly diverse group of taxa such as insects, crustaceans, spiders, scorpions, and centipedes. There are far more species of arthropods than species in all other phyla combined, and the number of undescribed species in the largest assemblage of arthropods, the insects, probably numbers in the tens of millions. Members of the phylum have been responsible for the most devastating plagues and famines mankind has known. Yet other species of arthropods are essential for our existence, directly or indirectly providing us with food, clothing, medicines, and protection from harmful organisms.

No, arthropoda comes from the Greek meaning joint legs or feet, hence the characterization of the phylum as having joint-appendages.

Yes, flies are arthropods. Phylum arthropoda has subgroup (clade) Pancrustacea containing Hexapoda and below it, the true insects, Insectae. Flies are in order Diptera (in several groupings below Insecta.)

No: in fact, parasites such as flatworms and roundworms also prey on earthworms. Earthworms are highly beneficial, not feeding off living organisms, but breaking down decomposing organic material.

Anthropods (humans) do have internal skeletons; arthropods (phylum arthropoda) by definition does not - instead they have external or exoskeletons.

Note that the term 'anthropod' should not be confused with 'arthropod' - anthropod is not a phylum nor taxon but is a general term meaning human or humanoid.

Arthropods are a category of invertebrate characterized by chitinous exoskeletons and segmented bodies; the three types are insects, arachnids, and crustaceans. Bodies of arthropods typically come in three sections, the head, the thorax, and the abdomen. Each of these is a segment. But some species, such as a centipede or a millipede, have more segments.

Yes. Arthropods have body cavities (coelomates); their main internal cavity is a hemocoel, which accommodates their internal organs and through which their blood circulates - they have open circulatory systems. Arthopods come from a lineage of animals that have a coelom, a membrane-lined cavity between the gut and the body wall that accommodates the internal organs. The coelom of the arthropod is reduced to small areas around the reproductive and excretory systems. Visit http://smackers0609.blogspot.com/Yes.

There are several methods arthropods use for gas exchange; insects have holes in their segments called spiracles, connected to a trachea and tubules which deliver oxygen directly to tissues without needing to go through a bloodstream; and also remove waste gasses. Arachnids may use a type of simple lung called a book lung, comparable to a book gill in a similar stacked spatial arrangement for some aquatic arthropods. Other marine arthropods use gills for gas exchange, such as crabs and lobsters; crabs can continue to use gills on land so long as they remain moist. The simpler and smaller arthropods are able to perform gas exchange across their entire body surface and need no additional specialized gas exchange structures.

The treatments can be compared to each other instead of to a control

Arthropods adapted to an aquatic environment that need to extract oxygen from water will have gills, for instance most (but not all) crustaceans, like crabs and lobsters. Crabs can come on land so long as their gills are kept moist; those that do usually seek out damp habitats.

It is not likely that the annelids evolved from the arthropods is as much as they are the much simpler of the two groups of organisms. The arthropods have a well developed open circulatory system, segmented muscles and a complex nervous system (including eyes and chemoreceptors, the antennae) and an exoskeleton.

Arthropods are characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages.

Bumblebees are insects, and all insects are arthropods.

Arachnids differ from other arthropods in that they have no antenna (nor wings, like many insects). They also use book lungs to breathe, rather than the gills or spiracle/trachea configuration. They have a body plan of only two sections (tagmata) and eight legs, although often with a modified forward pair different from most other arthropods.

Yes, by definition all arthropods are taxonomically related in the sense that they share membership in the same phylum (Arthropoda); although this does not necessarily mean they share a common ancestor.

I can give you few because based on our lesson, arthropods have 5 subclasses: These are the crustaceans, arachnids, insects, millipedes and centipedes.

Examples of crustaceans are crab,lobster, shrimp and crayfish. Examples of Arachnids are spiders , mites , scorpions and ticks. Insect Examples: lady bug, grasshopper, housefly , mosquito and butterfly. Of course examples of millipedes and centipedes are obvious.

1. There long primitive 555 million year old history allowed them to collonise almost every corner of planet Earth, they thrive in the world's oceans, land , and achieved fight. but what allowed them to become one of evolution's greatest success story?

1. they time of each living generation in an abosulute, why? since a bugs life is relatively short they mature quicker and eventually reproduce a lot of babies. the speed of life boosts their chace of survival and envolution can be pushed to the accelerator, this means they adapt quicker to their changing environment and thus helped them to forish on the most hospital of places.

now I answered you question so GIVE ME UR MONEY BI@$H!

sorry I hace spasmcindrome Xp

no, i dont know what they are, but they are not arthropods
