Arthropods
Arthropods have segmented bodies and exoskeletons. Some types of arthropods are crustaceans, insects, and arachnids.
851 Questions
Do arthropods have cehphlathorax?
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.
Members of this arthropod group have a body divided into a cephalothorax and an abdomen?
Members of class Chelicerata, order Arachnida and suborder Aranaea, being regular spiders. The cephalothorax bears the eyes, mouth, legs and musculature used to move these, and the abdomen contains the vital organs.
How do arthropods move nutrients from one parto f the body to anohter?
Arthropods do have a circulatory system to move oxygen and nutrients through their bodies, but it is an open design, meaning the organs and cells are bathed in circulatory fluid unlike our circulatory system which delivers blood to specific locations. Their internal body cavity is called a hemocoel, the fluid drains into open pores and is pumped by a simple dorsal heart. Their movements also help to move the fluid around. This liquid is called hemolymph and contains water, salts, proteins, carbohydrates and lipids, and an oxygen-carrying molecule.
What is the largest anthropod group?
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.
By count the most arthropod species fall under the Insecta class, with a million species described and millions estimated yet to be described. By count, insects are over half of all living animals and by some estimates may constitute up to ninety percent of all living animals on the earth. In biomass, krill take the top spot weighing in from up to half to three quarters of a billion tonnes, and thus having a huge significance in the food chain.
A basitarsus is the basal segment of an arthropod tarsus - any of the arthropod's articulations in its foot.
Do joints in an arthopods appendages give them flexibility and the ability to move?
Yes, jointing is critical in arthropod morphology owing to the general rigidity of the exoskeleton, and the very reason for the name of the phylum (Arthropoda loosely means "joint appendages"). Jointing provides mobility through flexion and extension of walking limbs, swimmerets, and wings; as also for signalling, digging, grasping, sensing, eating and other capabilities.
Pretty much all bugs are arthropods, with the exception of an informal usage of the word "bug" to describe a pathogen causing an illness. All insects are arthropods; non-insect arthropods like myriapods (centipedes and millipedes for example) are called bugs and are still arthropods. Arachnids including spiders and scorpions, which might be called bugs, are also arthropods; land crabs which might be referred to as "bugs" are arthropods.
In biology there is a group of insects called the "true bugs", including the shield bugs; also arthropods.
"Anthropod" isn't a phylum, but refers rather to a bipedal human or humanoid. The similar-spelled "Arthropod" should not be confused with it.
Arthropoda is a phylum under the animal kingdom characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages.
Are arthropods endothermic or ectothermic?
Well arthropods have no vertebrae so they are cold blooded (ectothermic).
What is an terresrial arthropod?
The term terrestrial usually just refers to something that lives on land. Ants, flying insects, woodlice, spiders, are all mostly land-dwelling arthropods.
When an arthropods molts it sheds its what?
Its exoskeleton, or 'armour'. A new one has already grown underneath it as molting begins, and only needs some time to harden out afterwards.
Why are centipedes in the phylum arthropoda?
Centipedes and other myriapods (like millipedes) belong in Arthropoda because they possess the physical and functional properties deemed characteristic of phylum arthropoda: joint appendages (legs, antennae), segmented body, and the chitinous exoskeleton.
Some examples of arthropods would be scorpions, sausage flies, dung beetles, the north american lobster, horseshoe crabs, eurypterids.
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.
What arthropods have exoskeletons which they can shed?
the bug that sheds it's exoskeleton is called CICADA.
answer 2. Bugs that live for more than a few months commonly shed their exoskeleton as they grow. Many spiders do so. [And their relatives the crabs and crayfish/lobsters.]
Cicadas shed their skin when they first emerge from the ground (where they will have spent several years living off a root), and they do it after first having climbed a small tree, so their discarded shells are conspicuous.
Arthropods are characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages. They are known for their near universal domain on planet earth, being at least half of all living animals by count (by some estimates up to ninety percent), and the heaviest by biomass. They also have more species than any other animal phylum, and a notoriously daunting task to completely classify since estimates are that millions of species have yet to be described, particularly in Insecta.
Which of the five classes of arthropods is the most diverse Explain?
Insecta...Cant Explain. Sorry. =) Try To Google It...
