Why are arthropods considered advanced?

The incredible diversity and success of the arthropods can be attributed to their extraordinarily adaptable body plan. A key feature is the evolution of myriad types of appendages (antennae, claws, wings, mouth parts) that allow arthropods to exploit nearly every niche on earth.

Why are arthropods considered to be very successful?

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 evolutionary advance of arthropods?

Here are some of the most obvious evolutionary advances that arthropods show over the simpler, more "primitive" mollusks and segmented worms: Jointed legs give arthropods more mobility on dry land than legless mollusks and worms.

What makes an arthropod unique?

All Arthropods share certain characteristics making them unique from other phyla. ... The muscles of an Arthropod are connected to the inside of the exoskeleton, because the animal lacks an internal skeleton of any type. The exoskeleton is made of a tough substance called chitin (KIE-tin).

Why are arthropods significant?

Many arthropods have extremely important roles in ecosystems. Arthropods are of ecological importance because of their sheer numbers and extreme diversity. ... This is an important role because it supplies the plants with the minerals and nutrients necessary for life.

Which feature is considered to be the most significant in arthropods being the most successful organisms on the earth?

Arthropods have a hard chitinous exoskeleton to provide structure and protect from predators.

What special adaptations have arthropods developed to be successful?

Early land arthropods evolved adaptations such as book lungs or trachea to breathe air. The exoskeleton was another important adaptation. It prevents an animal from drying out. It also provides support in the absence of buoyant water.

What are the advanced characteristics of phylum Arthropoda over annelida?

These animals occupy by far the widest variety of habitats on earth. The name arthropod means 'jointed foot. ' All arthropods have segmented bodies and are covered in a jointed, protective armor called an exoskeleton. Their body muscles attach to the inside of the exoskeleton.

How have arthropods evolved over time?

Arthropods represent the evolutionary pinnacle of the protostomes. It seems likely that arthropods evolved from the same root as the annelids and that the three main lineages of arthropods - the Chelicerata, the Crustacea and the Insecta - evolved independently from a common ancestor.

What is the most important feature of Arthropoda?

The important characteristics of arthropoda include: They possess an exoskeleton. They have jointed appendages. Their body is segmented.

How does the body structure of arthropods contribute to their success as a group?

Jointed appendages allowed arthropods to have much greater flexibility and range of movement. Advantages of having a hard outer layer are protection, water retention, structural support (particularly on land), and counterforce for attachment and contraction of muscles.

How do arthropods adapt to their environment?

Arthropods are animals with jointed appendages and a chitinous exoskeleton. They are adapted to live in terrestrial environments. Some of these adaptations include reduced body size, presence of antenna and compound eyes, complete digestive system, and breathing through trachea, gills or book lungs.

What role do arthropods play in the ecosystem?

Ecosystem Roles:

Arthropods are found in all consumers' roles of an ecosystem, whether they eat plants or animals, and some are important decomposers. They are important in the pollination of flowering plants. Some play an important role in soil aeration and water infiltration.

What advantages do arthropods have?

The external skeleton of arthropods is a highly efficient system for small animals. The exoskeleton provides a large surface area for the attachment of muscles and, in addition to functioning in support and movement, also provides protection from the external environment.
