Arthropods

Because all of the chemicals or chemicaly related toxens that are in the air and on the plants to kill bugs are deadly, but mistakingly butterflies eat the pollen off of plants which means they will apparenently die after they eat the pollen because it probably was sprayed.

an example of this besides the butterflies is oviously the bees.

also when people catch them sometimes it ingers them an that means they can't fly,or walk .it only depends where they got ingered.the consequinces for that is they will die

cause if they can't rely on their abilities then they can't escape or even do the natural things of life they where created to do . last of all i can think of is that the birds eat insects like bees,worms, butterflies,Spiders,and even more.

Yes. Arthropods are characterized by an exoskeleton made mostly from the tough protein chitin, also joint appendages and segmented bodies.

Insecta you nucking retards!

Earthworms decompose dead organisms

Crayfish are members of the crustacean family.

The arthropod body plan has a great deal to do with how they are classified. Insects are hexapods with three body sections, a head, consollidated thorax with three leg pairs, and an abdomen. The chelicerates, like arachnids, have two main body sections and eight legs. Myriapods have up to hundreds of sections each with a leg pair. Many crustaceans are decapods, have ten legs, often a fused cephalothorax and articulated abdominal segments like lobsters, crayfish, shrimp, prawns and krill; similar is true of crabs except the short abdomen (tail) is folded up beneath the thorax. Trilobites (now extinct) are named for having three longitudinal lobes.

They all have, it's what their name means in Latin. Insects, arachnids, crustaceans and centi/millipedes all have jointed legs.

No. Vertebrates are only one phylum (Chordata), all the others don't have a backbone. Those are literally everything but fish, amphibians, reptiles, birds and mammals.

An aquatic animal's nervous system would function pretty much the same as their land-based counterparts; also showing a similar degree of variation and complexity. The size and characteristics depend on the species, but the components in aquatic environment are the same as in the terrestrial: the basic unit of the nervous system is a nerve cell or neuron, which has an electrical resting potential created by an electrical potential difference across the cell membrane caused by ions such as sodium, potassium and calcium. This balance can quickly change or become depolarized as a result of a received stimulus, for example from a neighboring neuron via chemical transmitters across a gap (synapse) between the two adjacent nerve cells. The nerves are connected into neural networks, which, together with a brain, spinal cord and nerve bundles (ganglia) throughout the body, constitute the nervous system.

The degree of complexity varies with the organism's need to transport stimuli around the body. The simplest organisms, (including aquatic ones) don't use or need a nervous system. Notionally if you are unicellular there is little requirement for a nervous system, since ostensibly the purpose of a nerve network would be to propagate a signal between different parts of a large multicellular body. The bigger and more complex the organism and more complicated tasks tasks it needs to perform the more urgent the need for an organized means of transporting stimuli. Yet, some relatively large multicellular aquatic animals have nothing which we might term a nervous system, like the sea sponges (Porifera). Sea anemones have a primitive nervous system but no real brain and no dedicated sensory organs; the nerves facilitate responses to stimuli and other biochemical processes but are not centralized. Some like jellyfish are similarly de-centralized, evidencing a network of nerves and ganglia but again nothing we might call a brain, yet are capable of responding to stimuli, including detection of salinity, co-ordination of movement, and in some, specialized sensory structures and a response to light with simplified eyes (ocelli). Arthropods, like crabs, lobsters, shrimp, etc., have a ladder-like system of nerves on their underside with paired ganglia in each segment, terminating in a rather small brain around the esophagus. Cephalopods, for example octopi, often considered the most intelligent invertebrates, have well-developed senses and large centralized nervous system (brain) and have shown the ability to learn and employ mimicry or insight to solve problems. Aquatic mammals like dolphins have acute eyesight and hearing and large, highly developed brains, and evidence social behavior, co-operation, and significant problem-solving and learning abilities.

they can shoot webs at anything like spiderman and with their laser eyes

No, arthropods are coelomates

Crayfish are classified as arthropods, because of their characteristic segmented bodies, chitinous exoskeleton, and joint appendages.

Examples of arthropods would be insects like the tsetse fly, the bullet ant, the lightning bug; myriapods like the millipede, crustaceans like krill, lobster, crayfish, crabs.

Echinoderms includes such creatures as sand dollars, sea urchins, starfish.

Pollenization with the help of an insect (or bird, or bat) is called biotic or vector-based pollenization. Abiotic pollenization happens by virtue of wind or water.

Arthropods don't have backbones. The vertebral column or spine comprises individual bones (vertebrae) as part of an internal skeleton or endoskeleton. Arthropods by contrast have no bony internal skeleton, instead they rely on a chitinous external or exoskeleton, consequently they also evidence joint appendages and segmented body which characterize the phylum.

Jointed legs, exoskeleton, growth by molting.

The largest arthropod subphylum is Hexapoda. 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.

Many factors contribute to bird navigation during long distance migrations, including learning, instinct, their solar compass (perception of sun orientation and day length), landmarks, olfactory cues, and a curious ability still being researched called magnetoception (or magnetoreception) which enables them to detect the orientation of the earths magnetic field. The mechanism is not fully understood but some tests indicate that homing pigeons, for example, might exploit magnetite contained in small deposits around the beak. Another theory suggests that a complex protein called cryptochrome might affect bird vision by altering the sensitivity of retinal neurons such that, in effect, birds might be able to 'see' the earth's magnetic field.

Most only do so in larval/juvenile stages, when it's time to grow. Some arthropods such as tarantula females continue growing and molting until death. Also, when damage has occurred (torn off leg for example) molting can be induced earlier to develop and grow new appendages. :)

The exoskeleton of arthropods defines their gross morphology (as determined and maintained by principles of genetic expression); although life stages may evidence significant differences (egg and larval stages, versus adult shape, for example). Since the exoskeleton can't grow owing to its rigidity, arthropods need to periodically shed it in order to increase in size, a process called ecdysis.

well i don't know about non arthropods but this is what i know about arthropods:-

Arthropods have jointed legs and a head and segmented body parts called the thorax and abdomen. An arthropod's body is covered by a shell or a hard outer skin called an exoskeleton. It is made of a material called chitin. The exoskeleton has a special top layer, the cuticle, which is thick and tough. In crustaceans, the exoskeleton is sometimes called the carapace and hides the segmented body parts.

Under the arthropoda phylum are subphyla Chelicerata, Myriapoda, Crustacea, and Hexapoda. (There is also an extinct class Marrellomorpha and an the extinct Trilobite subphylum). The chelicerata include spiders, scorpions, mites, etc. Myriapods include centipedes and millipedes. Crustaceans include lobsters, krill, crabs, shrimp, woodlice, etc. Hexapoda include the class Insecta, the insects.

Comparten muchas características, es decir, son similares porque no tienen columna vertebral sino exoesqueleto y otros tienen cuerpo y patas articuladas y más características.

They share many characteristics, that is, they are similar because they do not have a spine but an exoskeleton and others have articulated body and legs and more characteristics.

By count the most arthropod species fall under the Insecta class, with a million species described and millions estimated yet to be described, evidencing an immense diversity. 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 Earth.
