- crustaceans (including slaters, prawn and crabs).
Why are arthropods the largest phylum?
It accounts for 80% of known animal species. So phylum Arthropoda is the largest phylum in the animal kingdom. Several factors contributed to the success of arthropods especially the terrestrial arthropods as they adapted to solve the problems of support, stability, desiccation and respiration.

Arthropods include creatures that live in water, on land and in the air. The phylum Arthropoda gets its name from two Greek words that mean “jointed leg.”
Which is the largest phylum?
Arthropod, any member of the phylum Arthropoda, the largest phylum in the animal kingdom, which includes such familiar forms as lobsters, crabs, spiders, mites, insects, centipedes, and millipedes. About 84 percent of all known species of animals are members of this phylum.

Which class of arthropods is the most successful?
The Class Insecta of the Arthropoda Phylum is by far the most successful and diverse taxon on planet Earth. In fact, there are more species of insect than any other species combined.
What is the phylum of arthropods?
What are the five common characteristics of arthropods?
All arthropods share a common set of characteristics that include having jointed limbs, an exoskeleton, good senses, and bilateral body symmetry. An exoskeleton is a hard, shell-like covering that protects an arthropod’s inside body parts.
What is the order of arthropods?
Insects belong to a larger group call Arthropoda which includes all animals with segmented legs, segmented bodies and exoskeletons. The phylum Arthropoda includes: spiders, ticks, mites, centipedes, millipedes, shrimps, lobsters, and many other organisms.
How many classes are arthropods divided into?
Arthropods are traditionally divided into 5 subphyla: Trilobitomorpha (Trilobites), Chelicerata, Crustacea, Myriapoda, and Hexapoda. Myriapoda is divided into four classes: Chilopoda (centipedes), Diplopoda (millipedes), Pauropoda, and Symphyla.
Do arthropods reproduce sexually or asexually?
Arthropods reproduce sexually and asexually. With most aquatic animal, sexual reproduction occurs externally. During asexual reproduction, parthenogenesis occurs. Parthenogenesis is when unfertilized eggs can develop into an arthropod.
In what group of arthropods would you classify the mosquito and why?
Mosquito is an arthropod classified under the class Insecta or the Hexapoda because it has a segmented body with three pairs of long and jointed legs meaning six legs in all.

- Caddisflies (Order: Trichoptera)
- Fleas (Order: Siphonaptera)
- Flies (Order: Diptera)
- Lacewings, Antlions & Mantidflies (Order: Neuroptera)
Which group of arthropods has three pairs of legs?
Insects are arthropods that have three body segments, three pairs of legs, one pair of antennae, and many have one or two pairs of wings. The three body sections are called the head, the thorax, and the abdomen. Wings and legs are attached to the thorax, the middle section.

Which phylum is the most successful group of animals?
In terms of numbers and the diversity of species, Phylum Arthropoda is the most successful group in Kingdom Animalia.
Why is phylum Arthropoda the most diverse?
Members of the phylum Arthropoda are characterized by jointed appendages and an exoskeleton of chitin. Arthropods are the most biologically successful group of animals because they are the most diverse and live in a greater range of habitats than do the members of any other phylum of animals.
