Chelicerates, a group that includes arachnids and horseshoe crabs, exhibit bilateral symmetry. This means their body can be divided into two mirror-image halves along a single plane that runs from head to tail. They typically show a clear distinction between the cephalothorax (the fused head and thorax) and the abdomen. Additionally, their body plan features paired appendages, which are characteristic of bilateral symmetry.
An arachnid is an invertebrate with only two body parts (the head and abdomen) but no thorax. It has eight legs and moves by moving it's legs forward in ripples. All arachnids have exoskeletons and the group's most famous member is the spider.
Arthropods are invertabrates (no backbone) which have segmented bodies and limbs. However, some arthropods, such as insects, have 3 body segments. Chelicerata - a group which includes spiders - have 2 segments, the cephalothorax and the abdomen.
I believe that the answer is insecta - hope this helps
The appendages of Arthropods are jointed. Each body segement has a pair of appendages. The original structure of Arthropod appendages was likely to have been biramous. Modern Arthropods can have either biramous or uniramous limbs. Biramous limbs branch out into two.
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.
because using the process of allimanation athropod would be the only possible answer
Flies are insects. They have six legs, three main body sections (head, thorax and abdomen) and have two sensory appendages. Spiders are arachnids. They have eight legs, two main body parts (head and abdomen) and never have sensory appendages.
chilopoda
The arthropod group containing crabs is known as crustaceans. This is a very large group of this phylum and contains so many species.
Arthropod
insects
insect of course.
yes they are
Spiders are not insects even though most people think so, they are different in many ways. Spiders have two body parts: the front body section, called the cephalothorax (seff-a-la-THOR-ax), and an abdomen. Insects have three body parts: a head, thorax, and abdomen. Spiders have eight legs while insects only have six.Another answer: Spiders are classed as Arachnids
The arthropod group
Butterflies belong to the arthropod group called insects. They are classified under the order Lepidoptera, which includes insects with large wings covered in scales.
