Arthropods

It will quickly try to hide under the nearby brush or wood.

Arthropods compete with humans for resources primarily through their roles in agriculture and urban environments. Insects like locusts and aphids can damage crops, leading to significant economic losses for farmers. Additionally, pests such as cockroaches and termites invade human habitats, consuming food supplies and causing structural damage. This competition can drive humans to invest in pest control measures, impacting both ecosystems and economies.

Division of labor in arthropods is possible due to their complex body structures and specialized appendages that allow for differentiation of roles among individuals. This specialization enhances efficiency in tasks such as foraging, reproduction, and defense, particularly in social species like ants and bees. The modular design of their bodies also supports this division, enabling different segments to evolve functions suited to specific tasks. Additionally, communication and social interactions within colonies facilitate coordinated efforts, further enhancing the benefits of division of labor.

Shrimps belong to the class Malacostraca, which is part of the phylum Arthropoda. This class includes a variety of crustaceans, such as crabs, lobsters, and prawns. Malacostracans are characterized by their segmented bodies and jointed appendages, typical features of arthropods.

The root words "pel" and "puls," derived from Latin, mean "to drive" or "to push." In the context of "repellent," the prefix "re-" suggests a reversal or opposition, while "pellent" relates to driving away. Thus, "repellent" conveys the idea of something that drives away, effectively deterring mosquitoes from coming near our skin.

Under phylum Arthropoda are several subphyla including subphylum Hexapoda which contains class Insecta (the insects); and Myriapoda which contains class Chilipoda (the centipedes) and class Diplopoda (the millipedes).

no it does not go on land

No, snails are molluscs (phylum mollusca), different from phylum arthropoda (arthropods). Arthropods are characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages.

In the mollusc phylum, you will see members like the cephalopods including octopi, squid and cuttlefish; or gastropods like snails and slugs.

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 the joint appendages and segmented body which characterize the phylum.

A variety of environments. Crustaceans live in watery places, etc.

An arthropod's main features are the segmented body, an exoskeleton made from chitin, and joint appendages.

Yes indeed

Chitin

Trilobites with flat eyes lived above the surface of the ocean floor, those with stalks burrowed below it. Those with very large or no eyes may have lived in lightless depths; those with all-round vision may have been prey, while those with binocular vision may have been predators. Just like animals living today, really.

For those arthropods with antennae, they will appear on the head. The location and count depends on the subphylum or group; for trilobites, hexapods (including insects) and myriapods they are located on the first body segment; for crustaceans which have two pairs they are located on the first and second body segments, with the smaller pair called antennules. Arachnids including spiders and scorpions have no antennae.

Yeah some can be :)

Happy hunting

The most well-known ones are crustaceans (crabs, lobsters, water fleas etc. but also barnacles!)

Terrestrial arthropods have a series of openings called spiracles at the body surface. Spiracles open into tiny air tubes called tracheae, which expand into fine branches that extend into all parts of the arthropod body

Well, spiders bite and then leave.

Ticks don't bite, they bury their heads in your skin. Little more dangerous, I think so...

Ticks also spread lyme disease, which is deadly.

The American lobster and European lobster belong to genus Homarus (H americanus and H. gammarus respectively). The Cape lobster was moved to genus Homarinus.
