Why are arthropods regarded

Arthopod is a word that is derived from a Greek word called Arthropoda. Thus, Arthopods are joint foot invertebrate animals having external skeletons. They don't have skin, instead they have hard body surfaces i. Arthopods are generally known for their joint limbs and cuticles.

Why are arthropods regarded as the most successful of all animal phyla? Category: pets fish and aquariums. 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. What is the most successful organism on earth? Do insects have hearts? What is the most successful insect? Why is the class Insecta regarded as the most successful group in the animal kingdom?

How are insects successful? Why is arthropods successful? How do you know this tick isn't an insect? The easiest thing to notice is that insects have 3 pairs of legs 6 of them while this tick has 4 pairs 8 legs.

Also, insects have 3 body regions head, thorax and abdomen while this tick appears to just have a head and a body. Both ticks and insects are members of the phylum Arthropoda, but ticks, along with spiders, are members of the class Arachnida, while insects belong to the class Insecta. Subphylum Hexapoda insects : Distinguished by their 3-parted bodies head, thorax and abdomen , usually having one or two pairs of wings, 6 legs, and their third body segment, the abdomen, is many-segmented.

Subphylum Chelicerata: "Chelicerae" are 3-segmented appendages vaguely jaw-like, adapted for eating many kinds of food; the oval, violet-colored things on the jumping-spider head at the right are chelicerare.

Subphylum Myriapoda: Many legs -- myria as in "myriad", and poda as in "podiatry," which is foot-doctoring. To see a much more complete, and confusing, breakdown, visit the NCBI taxonomy database. Keep in mind that many commonly occurring arthropods are tiny, even microscopic, such as Daphnias, sometimes called water fleas genus Daphnia. This divergence is believed to have occurred more than million years ago during the Cambrian Explosion, a period on Earth when many of the current groups of animals first evolved.

The evolution of arthropods occurred following the loss of body segments, development of specialised legs and a more developed head.

The chitinous exoskeleton acts as a form of armor for arthropods. Unfortunately, the chitinous shell is unable to grow and arthropods must moult their exoskeletons seasonally as they would otherwise limit their growth. The exoskeleton also serves as an anchor point for the internal muscles of arthropods which allow the animals to perform precise movements.
