What organisms are included in the class Myriapoda?
Myriapoda (from Ancient Greek μυρίος (muríos) ‘ten thousand’, and πούς (poús) ‘foot’) is a subphylum of arthropods containing millipedes, centipedes, and others. The group contains about 13,000 species, all of them terrestrial.
Which of these are characteristics of phylum Arthropoda?
Characteristic features of Phylum Arthropoda
They are triploblastic. They can be found in all types of habitats – land, water and soil. They have jointed limbs. The body is segmented into three regions – Head, Thorax and Abdomen.

What is the largest class of arthropods?
Answer and Explanation: The insects are the largest group of arthropods. Insects are distinctive from other arthropods because they have three divisions of their body: the head, thorax, and abdomen.
Which animal has 3 pairs of legs?
Insects
Insects are invertebrates with three pairs of legs, usually two pairs of wings, one pair of antenna, jointed appendages and three distinct body regions – head, thorax and abdomen. Insects belong to the largest phylum of animals known as arthropods.

How many animals are arthropods?
Using a ratio of 1 beetle to 3.9 other arthropod species derived from other methods (20–22) gives estimates of 5.9–7.4 million species of arthropods.
How do the three largest groups of arthropods differ?
The three largest groups of arthropods differ in their structure and number of segments and functions. Crustaceans have 2 pairs of antennae, 2-3 body sections, and a mandible. Chelicerates (spiders and relatives) have chelicerae, 2 body sections, and 4 pairs of walking legs.
Why arthropods are the largest group of animal kingdom?
Due to metamorphosis, there is less competition among larval and adult forms for food. Cockroaches can even survive nuclear radiations and poisoned earth. All these factors made arthropods the largest phylum among animals.
Why are arthropods important?
But arthropods are also responsible for a suite of activities that are beneficial to humans: pollinating crops, producing honey, eating or parasitizing insect pests, decomposing waste, and being food for a variety of birds, fish, and mammals. Farmland abounds with beneficial arthropods.
