It would either have to be a hexagon or an octagon. I'm not a hundred percent sure.
thin with diffrent 10 segments
Arachnids such as spiders and scorpions have chelicerae.
Spiders. horseshoe crabs, sea spiders, mites, ticks...and other arachnids.
pedipalps
From the phylum of arthropods is where the Spiders belong, it has chelicerae with fangs that inject venom and has eight leg. This air-breathing arthropods has 10 types, and based on science studies, an average spider has 2,230,000 cells.
A garden Spider Has 8 Legs
Like many other spiders, the jaw parts of black widow spiders are too small and delicate to chew up their prey. So these spiders pump digestive juices into the bodies of their prey. After a while, the digestive fluids will have liquified all the digestible content inside the prey's exoskelaton, and then the spider sucks the fluid back into its own body. Some other kinds of spiders have more robust chelicerae (the parts that are terminated by the fangs), and they have tooth-like protrusions on them. These spiders use their chelicerae to chew up the bodies of prey, adding digestive juices in the process, and so they are able to get nutrition from parts of the prey bodies that black widows can't get at.
Animals with outer shells and segmented bodies are members of the phylum arthrapoda. This phylum includes insects and chelicerae's (spiders, millipedes, etc.).
Spiders share the same characteristics as others in the chelicerae subphylum including using a pointed appendage to grasp food. All chelicerata, including spiders, have six pairs of appendages that are not branched.
A spider uses its chelicerae to catch its prey by stabbing it and injecting venom into it.
The prey is captured by the pedipalps and the sting is inserted in it, the paralyzed or killed prey is sucked using the chelicerae.
The shape is like all spiders a sack and a body
Two pedipalps (which function more or less like arms) and behind them Eight legs And some spinnerets (that give silk sort of the way a cow's teats give milk) Spiders also have chelicerae, which are two short things that are tipped with fangs. Spiders do not have antennae.
