What do chelicerata do?

Members of this group are herbivores, detritivores, predators, parasites, and scavengers. Most chelicerates suck liquid food from their prey. Many chelicerates (such as scorpions and spiders) are unable to eat solid food due to their narrow gut. Instead, they must expel digestive enzymes onto their prey.

What is the Chelicerate opisthosoma?

Chelicerates’ bodies consist of two tagmata, sets of segments that serve similar functions: the foremost one, called the prosoma or cephalothorax, and the rear tagma is called the opisthosoma or abdomen.

What is a Chelicerate in biology?

The chelicerates are arthropods that are named for their feeding appendages called chelicerae. The chelicerae are specialized pair of appendages that appear before the mouth. The pedipalps are specialized appendages that are found next to the chelicerae and in front of the first walking legs.

What are the characteristics of chelicerata?

Chelicerata is a division within the Arthropoda, containing animals such as spiders, scorpions, harvestmen, mites and ticks. Like all arthropods, they have a segmented body and segmented limbs and a thick chitinous cuticle called an exoskeleton. Chelicerates have two body segments; a cephalothorax and an abdomen.

What are the two parts of the Chelicerata?

The Chelicerata can be defined as those arthropods with the anteriormost appendages as a pair of small pincers (chelicerae) followed usually by pedipalps and four pairs of walking legs, and with the body divided into two parts: the prosoma (corresponding approximately to the cephalothorax of many crustaceans) and the opisthosoma (or abdomen).

Is the opisthosoma a part of the prosoma?

The opisthosoma is the posterior part of the body in some arthropods, behind the prosoma (cephalothorax). It is a distinctive feature of the subphylum Chelicerata (arachnids, horseshoe crabs and others).

Where is the opisthosoma located in an arachnid?

The opisthosoma is the posterior part of the body in some arthropods, behind the prosoma (cephalothorax). It is a distinctive feature of the subphylum Chelicerata ( arachnids, horseshoe crabs and others).

What kind of arachnid is a Chelicerata?

Chelicerata (kəlĬs´ərät´ə), subphylum of Arthropoda, including the horseshoe crabs (order Xiphosura), the arachnids (class Arachnida), and the sea spiders (class Pycnogonida).
