Spiders are chelicerates and therefore arthropods.[6] As arthropods they have: segmented bodies with jointed limbs, all covered in a cuticle made of chitin and proteins; heads that are composed of several segments that fuse during the development of the embryo.[5] Being chelicerates, their bodies consist of two tagmata, sets of segments that serve similar functions: the foremost one, called the cephalothorax or prosoma, is a complete fusion of the segments that in an insect would form two separate tagmata, the head and thorax; the rear tagma is called the abdomen or opisthosoma.[6] In spiders the cephalothorax and abdomen are connected by a small cylindrical section, the pedicel.[7] The pattern of segment fusion that forms chelicerates' heads is unique among arthropods, and what would normally be the first head segment disappears at an early stage of development, so that chelicerates lack the antennae typical of most arthropods. In fact chelicerates' only appendages ahead of the mouth are a pair of chelicerae, and they lack anything that would function directly as "jaws".[5][8] The first appendages behind the mouth are called pedipalps, and serve different functions within different groups of chelicerates.[6
In a spiders abdomen, they have the digestive tract, and the reproductive organs.
The front half is called the cephalothorax and the back half is the abdomen.
Thorax
A. Spiders have a cephalothorax and abdomen insects have a head a thorax and an abdomen.
Spiders typically have a cephalothorax, and an abdomen.
In the abdomen of a spiders body.
abdomen
no they have an abdomen, and a cephalothorax.
The Lobster has a abdomen,Same as spiders the abdomen is really hard :) thats how they are protected
i think that a spiders abdomen is acually really softcause when you kill one it is really smashable any ways im really smart huh?nlsxisksq;odhupf
Head and abdomen.
Spiders make the strands of web with special organs called "spinnerets" that are near the tip of the abdomen of the spider.
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
Spiders make their web by producing silk threads from their spinneret glands. These glands are located at the tip of their abdomen.
The arachnids group has a body that is divided into a cephalothorax and an abdomen. This group includes spiders, scorpions, ticks, mites, and more.
