What is the difference between arthropods and annelids?

Answer 1

An arthropod is an invertibrate that has an exoskeleton, a segmented body, and jointed attachments called appendages, and an annelid is an animalia with worm-like features.

Answer 2

Arthropod
Any member of the largest phylum, Arthropoda, in the animal kingdom. Arthropoda consists of more than one million known invertebrate species in four subphyla: Uniramia (five classes, including insects), Chelicerata (three classes, including arachnids and horseshoe crabs), Crustacea (crustaceans), and Trilobita (trilobites). All arthropods are bilaterally symmetrical and possess a segmented body covered by an exoskeleton containing chitin, which serves as both armour and a surface for muscle attachment. Each body segment may bear a pair of jointed appendages. The phylum includes carnivores, herbivores, omnivores, detritus feeders, filter feeders, and parasites (see parasitism) in nearly all environments, both aquatic and terrestrial.

Spider
Any of numerous arachnids of the order Araneae, having a body divided into a cephalothorax bearing eight legs, two poison fangs, and two feelers and an unsegmented abdomen bearing several spinnerets that produce the silk used to make nests, cocoons, or webs for trapping insects.

Answer 3

Arachnids- A body with two segments, eight legs, spinnerets, no chewing parts, no wings, and the presence of chelicerae, which Spiders use to hold prey, and in most cases, inject venom.

Crustaceans- Crustacean anatomy is characterized by an external skeleton and a segmented body. Composed of a series of hard segments called somites. They have two sets of jaws in front of the mouth, and have several appendages near the mouth that act as feeding aids. The limbs usually start with a pair of developed arms with claws. Behind these are 4 pairs of walking legs, and as the claws are classed as legs. They have a total 10 LEGS.

Answer 4

Annelid animals Arthropods

1

Have true body cavity (coelomic cavity) not

filled with blood.

1 The coelomic cavity is blood filled.

2

They have lateral appendages for

locomotion in the form of chitineous setae

or parapodia.

2 They have jointed legs for locomotion.

3

Annelids like earthworm and leech do not

have chitinous exoskeleton.

3 They have chitinous exoskeleton.
