Question

Differences between annelids and arthropods.

Answer 1

Hint: A phylum is a level of classification or taxonomic rank in biology that is below kingdom and above class. Although the International Code of Nomenclature for algae, fungi, and plants accepts the terms as equivalent, the division has traditionally been used instead of phylum in botany.

Complete answer:
The annelids, also known as ringed worms or segmented worms, are a large phylum that includes ragworms, earthworms, and leeches. An arthropod is a type of invertebrate that has an exoskeleton, a segmented body, and paired jointed appendages. Arthropods are members of the Euarthropoda phylum, which also includes insects, arachnids, myriapods, and crustaceans.

Annelids and Arthropods are two distinct types of organisms. The distinctions between annelids and arthropods are listed below.

Annelids	Arthropods
From head to tail, metameric segmentation is observed where the body is segmented.	The body is not completely segmented due to incomplete metameric segmentation.
Annelids' circulatory systems are closed.	Arthropods have a free-flowing circulatory system.
The body is divided into several segments that are all the same.	The body is divided into several specialized sections.
Annelids do not have appendages.	Arthropods have appendages that are joined together.
They are known as segmented worms.	Animals with jointed legs are what they are called.
The true body cavity they have is called a coelom.	The presence of a blood-filled body cavity, known as a 'hemocoel.'
The majority of annelids are hermaphrodites. For example, Earthworm.	They are divided into two sexes.For example, Crab.

Note: Annelids have no lungs and obtain oxygen through their skin! There are an estimated 9,000 different Annelid species! Annelids can grow from 1 millimeter to over 3 meters in length! Some Annelids are hermaphrodites, which means they have both male and female sex organs! Crustaceans, insects, arachnids, centipedes, millipedes, sea spiders, pauropods, symphylans, springtails, proturans, two-pronged bristletails, three-pronged bristletails, and king crabs are the 13 classes of arthropods.
