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.


What is the function of chelicerae?

For grasping, feeding and piercing it's prey


Which subphyla of arthropoda is caracterized by animals lacking antennae?

The subphyla of arthropoda that does not have antennae is chelicerata. Chelicerates, which include spiders and scorpions, are missing the first segment of nerve ganglion which controls antennae in other arthropods.


Do chelicerates have wings?

no chelicerates are mostly spiders or scorpions or horseshoe crabs


Which arthopods have chelicerae?

Arachnids such as spiders and scorpions have chelicerae.


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


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.


How many segments do chelicerates have?

3


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


What do chelicerae and pedipalps do?

The prey is captured by the pedipalps and the sting is inserted in it, the paralyzed or killed prey is sucked using the chelicerae.
