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.

What other Phylum is closely related to arthropods and Why?
Roundworms (Nematoda) are related to arthropods because they both molt.Note; Crustaceans are arthropods. :P
What makes a tarantula an arthropod?
Tarantulas and other spiders are classified as arthropods by virtue of their physical characteristics. In taxonomic classification arthropods branch into two major subcategories, the chelicerates which include arachnids, and the mandibulates which includes the myriapods, crustaceans and insects. These all share the broad definition of arthropoda which is characterized by joint appendages and possession of an exoskeleton.
How many sections are arthropods divided into?
The three main classes of arthropods are: insects (cockroachs, ants, flies, bees, beetles, butterflies), crustaceans (crabs, lobsters, shrimps, barnacles) and arachnids (scorpions, spiders, mites). Other classes are onychophorans (velvet worms), diplopods (millipedes) and chilopods (centipedes).
How are in six different from other arthropods?
Assuming this question is how are insects different from other arthropods, insects fall into hexapods which includes insects, springtails and a few other groups of arthropods with six legs. Insects are different from other hexapods in that they possess a structure called a tentorium which is an internal support skeleton in the head made by extensions of the exoskeleton into the head.
Can Arthropods have gills?
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.
How do you know something belongs to the crustaceans group of arthropods?
Crustaceans differ from other arthropods in that they have biramous (two-part) appendages and the nauplius larval form.
What other Phylum is closely related to arthropods and Why?

What is the difference between chelicetara and other arthropods?
Chelicerae are specialized feeding appendages found in chelicerates, a subphylum of arthropods that includes spiders, scorpions, and horseshoe crabs. They are used for grasping and tearing food. Other arthropods, such as insects and crustaceans, have different types of mouthparts for feeding, like mandibles or maxillae.
Are all arthropods insects?
No. Arthropoda is a phylum, containing the classes Insecta, Arachnida, Crustacea and Myriapoda - insects, arachnids, crustaceans and centi/millipedes. So all insects are arthropods but not all arthropods are insects. ^^
How are lobsters and chitin related?
Lobsters are crustaceans, and chitin is the hard polysaccharide substance that makes up the outer shell (exoskeleton) of crustaceans. Chitin also makes up the exoskeletons of other arthropods (insects, etc.). It helps to strengthen the cell walls of fungi and the shells of mollusks as well.
What kingdom are arthropods in?
Arthropods belong to the insect kingdom, because they have 6 legs, and all of their other features are like any other insects features.
What distinguishes crustaceans from all other anthropods?
Crustaceans are distinguished from other arthropods in that their appendages are biramous (branch into two parts), and that they have a larval form which has a single eye and antennae used for swimming (nauplius). One might also assume they differ from most other arthropods in that they are aquatic, but there are both aquatic non-crustaceam arthropods (like the horseshoe crab and the sea spider), and non-aquatic crustaceans (like the terrestrial woodlouse). Note that the term "anthropod" should not be confused with arthropod - the former is a broad term and not a taxon, meaning human or human-like.
Are worms anthropods?
No, worms are not arthropods. Arthropods are invertebrates with an exoskeleton, segmented body, and jointed appendages, such as insects, spiders, and crustaceans. Worms, on the other hand, are soft-bodied invertebrates belonging to phyla such as Annelida or Nematoda.
What makes a tarantula an arthropod?
Tarantulas and other spiders are classified as arthropods by virtue of their physical characteristics. In taxonomic classification arthropods branch into two major subcategories, the chelicerates which include arachnids, and the mandibulates which includes the myriapods, crustaceans and insects. These all share the broad definition of arthropoda which is characterized by joint appendages and possession of an exoskeleton.
What part of speech is antennae?
The word "antennae" is a noun. It refers to the sensory appendages on the heads of insects, crustaceans, and some other arthropods.
How many sections are arthropods divided into?
