Do chelicerates have wings?
no chelicerates are mostly spiders or scorpions or horseshoe crabs
Do chelicerates have antennae?
No
Are wings found in insects and chelicerates?
Yes, wings are found in insects, but not in chelicerates such as spiders and scorpions. Chelicerates have evolved a different body plan that does not include wings for flight.
What are Arthropods with fangs?
chelicerates
How many segments do chelicerates have?
3
Jaws found on some arthropods?
chelicerates
How many body segments do chelicerates have?
3
What are the jaws found on some arthropods?
chelicerates
Which arthropod group has no antenna?
The Arachnid class is an example of an arthropod group characterized by possessing two main body segments, eight legs, but having no antennae. All arthropods except chelicerates and proturans have antennae. (The chelicerates include arachnids, horseshoe crabs, and sea spiders.)
What structures of chelicerates are analogous to the antennae of chilopods and other mandibulates?
In chelicerates, the chelicerae (mouthpart) are analogous to the antennae of chilopods and other mandibulates. Chelicerae are a pair of appendages located near the mouth used for feeding and defense. They are sensory and help in manipulating food, similar to how antennae function in other arthropods.
Which group of arthropods lack jaws?
Chelicerates (crabs, Pycnogonida, and Mercostonata) are arthropods that lack jaws.
Where is a spiders abdomen?
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
