What is Maxillipede?
Definition of maxilliped : any of the crustacean appendages that comprise the first pair or first three pairs situated next behind the maxillae.
What does Cheliped mean in biology?
Definition of cheliped : one of the pair of legs that bears the large chelae in decapod crustaceans.
What do Maxillipeds do?
Maxillipeds are appendages modified to function as mouthparts. Particularly in the less advanced decapods, these can be very similar to the pereiopods. Pereiopods are primarily walking legs and are also used for gathering food. They are also the ten legs from which decapods take their name.
What does a cephalothorax do?
The cephalothorax or prosoma is the anterior most of the two body parts of arachnids (the other part being the abdomen or opisthosoma). The cephalothorax features the eyes, mouth and legs of the arachnid. The cephalothorax is more rigid than the abdomen and contains the muscles used to operate the limbs.
What animals have maxillipeds?
They include annelids (segmented worms), mollusks, arthropods, arachnids, crustaceans, odonates (mayflies, dragonflies, and damselflies), stoneflies, true bugs, beetles, caddisflies, and true flies.
What’s the cephalothorax definition?

What is a cephalothorax on a spider?
The cephalothorax is the first of 2 body parts on a spider. It is a combination of the head and thorax, and on it are found the legs, eyes, pedipalps, chelicerae, and other mouthparts.
Is cephalothorax found in earthworms?
Cephalothorax is present in arachnids. Option C is not correct. Option D Metathorax: Metathorax is the segment that bears the hindwings in most winged insects, though sometimes these may be reduced or modified as in flies, the metathorax is usually present in insects not in earthworm.
Why are the maxillipeds related to eating?
Long antennae are organs for touch, taste, and smell. The mandibles, or jaws, crush food by moving from side to side. Two pairs of maxillae hold solid food, tear it, and pass it to the mouth. Of the eight pairs of appendages on the cephalothorax, the first three are maxillipeds, which holdfood during eating.
