Differbetween
The key difference between arthropods and annelids is that the arthropods are a group of invertebrates that includes animals having a segmented body, an exoskeleton and paired appendages while annelids are another group of invertebrates that includes segmented worms possessing transverse rings.

How do arthropods differ from annelids?
Annelid species typically have tubelike bodies consisting of numerous segments, known as somites, covered in stiff hairlike structures called setae that help the annelid move forward. ... On the other hand, arthropods have more complex segmented bodies covered in an exoskeleton that protects their organs and muscles.
What is Annelida and Arthropoda?
Annelida: Annelida refers to an animal phylum that consists of coelomates with elongated, segmented body. Arthropoda: Arthropoda refers to an animal phylum that consists of haemocoelomates with a segmented body, joint appendages, and chitinous exoskeleton.
Are arthropods and annelids closely related?
Annelids and arthropods have long been considered each other's closest relatives, as evidenced by similarities in their segmented body plans.
What is the difference between Arthropoda and Mollusca?
Hint: Arthropods and molluscs are both invertebrates. Arthropods are organisms having exoskeleton and segmented bodies with paired appendages.
...
Differentiate between Arthropoda and Mollusca.
| Arthropoda | Mollusca |
|---|---|
| Arthropods have wings to fly with jointed legs usually to their abdominal segments. | Molluscs have a muscular foot that helps in locomotion. |
Is butterfly an arthropod?
Arthropods are a motley crew: cockroaches, crabs, butterflies, beetles, centipedes, scorpions, shrimp, spiders, lobsters, lice, ticks, termites, potato bugs, and sea monkeys (a.k.a., brine shrimp) — they're all examples of arthropods.
Is a jellyfish an arthropod?
Since about 75% of all animal species are arthropods, they represent the largest invertebrate group. ... Cnidarians are also simple aquatic animals like sponges, but their possession of a nerve system makes them more complex than sponges. Jellyfish, hydras, sea anemones, and corals make up the four classes of cnidarians.
What is the meaning of annelida?
The annelids /ˈænəlɪdz/ (Annelida /əˈnɛlɪdə/, from Latin anellus, "little ring"), also known as the ringed worms or segmented worms, are a large phylum, with over 22,000 extant species including ragworms, earthworms, and leeches.
What is the definition of arthropods?
: any of a phylum (Arthropoda) of invertebrate animals (such as insects, arachnids, and crustaceans) that have a segmented body and jointed appendages, a usually chitinous exoskeleton molted at intervals, and a dorsal anterior brain connected to a ventral chain of ganglia.
How do Arthropods respire?
Aquatic arthropods respire with gills. Terrestrial forms rely on diffusion through tiny tubes called trachea. Trachea are cuticle-lined air ducts that branch throughout the body, and open in tiny holes called spiracles, located along the abdomen.
What is the oldest arthropod?
A 508-million-year-old critter — one that looks like a weird lobster with 50 legs, two claws and a tent-like shell — is the oldest known arthropod with mandibles on record, a new study finds. Arthropods are a group of invertebrates that includes spiders, insects and crustaceans.
Why are arthropods so successful?
An arthropod regularly sheds its exoskeleton to grow. ... The incredible diversity and success of the arthropods is because of their very adaptable body plan. The evolution of many types of appendages—antennae, claws, wings, and mouthparts— allowed arthropods to occupy nearly every niche and habitat on earth.
How do arthropods reproduce?
Arthropods reproduce by sexual reproduction, which involves the generation and fusion of gametes. Most arthropods are either male or female, and they undergo internal fertilization. ... During most of their life cycle, arthropods have the segmented bodies described earlier.
