Jun 20, 2024 · 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. Learn more about arthropods in this article.
Condylipoda Latreille, 1802. Arthropods ( / ˈɑːrθrəpɒd / ARTH-rə-pod) [20] are invertebrates in the phylum Arthropoda. They possess an exoskeleton with a cuticle made of chitin, often mineralised with calcium carbonate, a body with differentiated ( metameric) segments, and paired jointed appendages.
Oct 4, 2019 · Arthropods are a lineage of life that developed skeletons on the outside – their hard shells, made of a material called “chitin” – instead of on the inside for structural support.
Arthropods are a motley crew: cockroaches, crabs, butterflies, beetles, centipedes, scorpions, shrimp, spiders, lobsters, lice, ticks, termites, potato bugs, and sea monkeys (a.k.a., brine shrimp) — they’re all examples of arthropods.
All arthropods are bilaterally symmetrical and possess a segmented body covered by an exoskeleton containing chitin, which serves as both armour and a surface for muscle attachment. Each body segment may bear a pair of jointed appendages.
There are more than a million known species of arthropods. There may actually be ten times that many. Arthropods include insects, spiders, lobsters, and centipedes. The arthropods pictured in Figure below give just a hint of the phylum’s diversity.
May 6, 2024 · Arthropods have open circulatory systems with a dorsal tubular heart and a network of short, open-ended arteries circulating the body fluid (hemolymph) through the body cavity (hemocoel).
Essentially, arthropods are characterized by possessing jointed limbs and an exoskeleton. They are the most successful animal Phylum on the planet, in regards to population size and species diversity. There is thought to be over 2 million types of arthropod in today’s world.
Jun 20, 2024 · Arthropod - Exoskeleton, Segmented, Jointed: Most arthropods are small animals; only aquatic forms can attain substantial sizes. The numbers and diversity of arthropods are enormous and they are found in almost all of the habitats that cover the Earth's surface.
Arthropods are a lot more than just delicious feasts and disgusting pests. Before we go too far, we need to figure out exactly what an arthropod is.
