What are the characteristics of an anthrpod?

Answer 1

Arthropods form the Phylum Arthropoda.

Their characteristics include:

Segmentation, in the sense of having heads, thoraxes and abdomens or cephalothoraxes and abdomens. Those that are mentioned are just the 'main' segments.

Jointed legs.

An exoskeleton. This is a hard covering, nonpermittive of growth as it is on the outside. Thus it must be shed periodically by ecdysis. Thus arthropods are part of the Ecdysozoa.

Arthropods include millipedes and centipedes (Diplopoda and Chilopoda), insects (Insecta), arachnids (Arachnida) and crustaceans (Crustacea) and sea Spiders (Pycnogonida).

The mouthparts differ between the so called Chelicerata (includes arachnids and sea spiders) and the Mandibulata (includes insects and crustaceans and millipedes and centipedes). The mouthparts are, expectedly from the names, chelicerae and mandibles respectively.

Note that not all six legged arthropods are insects. There are non-insect hexapods as well, such as springtails and silver fish and bristle tails. Crustaceans have 10 or more legs. Arachnids have 8. Millipedes have two pairs of legs per segment and centipedes have one pair of legs per segment.

Phylogeny-wise it appears that insects (the only winged arthropods) are simply winged crustaceans i.e. insects are the most derived of the crustacean-insect clade.

Answer 2

Arthropods are characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages. They have an internal body cavity (hemocoel) and an open circulatory system which employs hemolymph, a fluid that does not distinguish between interstitial fluid like lymph and oxygen carrying fluid like blood as in most vertebrates. They use a copper-based oxygen carrier molecule instead of the iron-based hemoglobin, which floats unbound around in the hemolymph and is not bound to blood cell proteins. They do not have a dedicated and separate branch of their circulatory system just to oxygenate; internal organs (and cells) are simply bathed in this fluid. Their nervous system is 'ladder-like' on their ventral surface, and their brains formed around the esophagus from fused segment nerve ganglia.

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.

Answer 3

all anthropods have segmented bodies.each kind of leg does a unique job. most anthropods have special sense organs called anthenas that can help smell and feel things and can also detect sound or light

Answer 4

= Atropods are some sort of living animal== Atropods are some sort of living animal=

Answer 5

Arthropods include an incredibly diverse group of taxa such as insects, crustaceans, spiders, scorpions, and centipedes. Rhyan was here :-p arkive.org

Answer 6

they have eight legs and they are harry and most of them are spiders

Answer 7

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

Answer 8

Basically any insect or arachnid is considered a anthropod
