Members of this phylum include copepods, horseshoe crabs, scorpions, spiders, and insects. Lobster's unique sounds defy predators Scientists now understand more about the unique way spiny lobsters create sound to ward off predators. Using a method of sound production resembling that of stringed instruments, spiny lobsters startle attackers by emitting loud, raspy noises.

Skip navigationals BIOMEDIA MUSEUM BIOLOGICAL SCIENCES University of Paisley Glossary* Gallery^ ARTHROPODA Unit 1 - Introduction The arthropods are by far the most successful phylum of animals, both in diversity of distribution and in numbers of species and individuals. They have adapted successfully to life in water, on land and in the air. About of all known animal species belong to the Arthropoda - about 800,000 species have been described, and recent estimates put the total number of species in the phylum at about 6 million. Arthropods are found in a greater variety of habitats than any other animal group; on top of mountains, at great depths in the ocean and in the icy wilderness of Antarctica. They can survive great extremes of temperature, toxicity, acidity and salinity. Now extinct, TRILOBITES represent the oldest known examples of arthropods. An extremely diverse phylum with many classes both large and small, there are several classifications of the phylum. You will find only an abbreviated version on the Taxonomy Table page which will be expanded in other relevant units (e.g.

THE ARTHROPODA - SHRIMP, CRABS, SPIDERS INSECTS, ET AL. Arthropoda means jointed leg, and refers to the jointed chitinous exoskeleton that is the hallmark of the most diverse phylum, with over 500,000 species. The Phylum Arthropoda consists three great groups: 1) the Superclass Crustacea, which includes shrimp, lobsters, isopods, and many other classes; 2) the Superclass Unirami, which includes the millipedes (and relatives, and the insects; and 3) the Chelicerata, which includes the horseshoe crabs, the scorpions, and the spiders, among others. The Crustacea are mostly aquatic, the Unirami mostly terrestrial, and the Chelicerata, is split between marine and terrestrial forms. Above, is Ligia occidentalis , the rock isopod, or "cucarachas del mar". It is an active scavenger on rocky beaches and be disquietingly abundant. It is also quite large reaching in excess of 10 cm. It is especially densely populous along the sea wall at Puerto Penasco. Apparently, although acting fully terrestrial, they cool by evaporation and must replenish there fluids from the sea. Curiously they often seem to migrate endlessly in one direction along the sea wall, but they must turn around some time. They also exhibit a marked diurnal color cycle, light colored during the night, as above, and dark during the day.

Arthropoda Eastern Hemisphere Arthropoda (Ar-THROP-a-duh) is located in the Trifid Nebula of the Sagittarius arm of the Milky Way galaxy, one of a handful of Outer System planets discovered by the flurry of Andromeda probes launched during the mid-21st century. Slightly smaller than Earth (6,000 miles in diameter), it is a mineral gift basket but has a climate hostile to humans, with a toxic atmosphere and intense heat. Most humans agree that sending Mansects there was a stroke of genius, since the bugheads love nothing better than mining and tunneling and were perfectly happy to have their own planet, where they could bask in the heat of three suns and breathe that sweet sulfuric acid and carbon monoxide. Arthropoda is rich in a number of important minerals not found on Earth, mostly crystal compounds and superconductive ceramics which have revolutionized Earth technology. They are also at the heart of Mansect technology, although the way each world uses these materials is quite different. The planet has an extremely hard crust and very little free surface water except at the equator, which is banded with extensive swamps and steamy lakes. Most Mansect cities are located in or near

Hexapoda image from Tree of Life Salticidae The arthropods constitute the most successful and diverse form of life on Earth, constituting millions of species in a diverse range of habitats, and varying in size from microscopic to quite large. The name "arthropod" comes from the Greek, arthros jointed, and podes , feet. Hence, jointed feet. All arthropods possess a jointed rigid exoskeleton, which both supports the musculature and protects the animal. The exoskeleton is formed by the cuticle, a protective layer composed mostly of chitin, long chained molecules of the sugar acetyl glucosamine, which when cross-linked form tough fibers embedded in a protein matrix As the animal grows it has to shed its exoskeleton at regular intervals, a process known as

Keywords: Arthropoda, arthropod, Ecdysozoa, Tactopoda, Onychophora, Euarthropoda, Tardigrada, Arachnomorpha, Trilobita, Chelicerata, Crustacea, Mandibulata, Atelocerata, Hexapoda, segmentation, ecdysis Introduction Arthropods are bilaterally symmetrical segmented animals with paired and usually jointed appendages, on some or all of the body segments, with chitinous claws. The body is surrounded by a tough organic or organic-mineral cuticle, incorporating a -chitin, which functions as an exoskeleton. In order for the animals to grow, the exoskeleton must be moulted regularly. The mixocoel includes metanephridia and, except in tardigrades, an ostiate heart. Segments are added from a posterior growth zone during ontogeny. At least half of the described species of living animals are arthropods (mostly insects), but arthropods are less common as fossils. The most familiar group of fossil arthropods is undoubtedly the trilobites. Fossil groups have been incorporated into arthropod classification systems at least since the 18th century, but important new finds - especially of very early stem group organisms, such as those of the

It is the second most prominent order of terrestrial arthropods , after the uniramians . Most of its marine representatives are extinct, but were prominent in the Paleozoic and included some fearsome predators. Click on the buttons below to learn more about the Cheliceramorpha.

J.K.Clark, University of California Statewide IPM Project Lady Beetles (Coleoptera: Coccinellidae) Lady beetles, ladybugs, or ladybird beetles are among the most visible and best known beneficial predatory insects. Over 450 species are found in North America. Some are native and some have been introduced from other countries. Most lady beetles in North America are beneficial as both adults and larvae, feeding primarily on aphids. They also feed on mites, small insects, and insect eggs. The two exceptions are the introduced Mexican bean beetle, Epilachna varivestis, and the squash beetle, Epilachna borealis. The adults and larvae of both species feed on plants. Appearance Lady beetles are usually red or orange with black markings. Some lady beetles are black, often with red markings. They have alligator-like larvae. Habitat (Crops) Many crops benefit from lady beetles. They are helpful for growers of vegetables, grain crops, legumes, strawberries, and tree crops; however any crop that is attacked by aphids will benefit from these beetles.

Coccinella septempunctata (Coleoptera: Coccinellidae) Sevenspotted Lady Beetle The sevenspotted lady beetle, repeatedly introduced to North America from Europe for the biological control of aphids, was established in the early 1970s in New Jersey, apparently from an accidental introduction. It has since spread naturally or been introduced to many northeastern and north central states. C. septempunctata may be a more effective predator than some native lady beetle species, displacing them in some areas. Appearance Comparatively large (7-8 mm) with a white or pale spot on either side of the head. The body is oval, and has a domed shape. The spot pattern is usually 1-4-2, black on the orange or red forewings. Lady beetle larvae are dark and alligator-like with three pairs of prominent legs, growing to 7-8 mm in length. Eggs are spindle shaped and small, about 1 mm long. Habitat (Crops) Aphid infested crops, including potatoes, legumes, sweet corn, alfalfa, wheat, sorghum, and pecans. Pests Attacked Reported prey include pea, cowpea, green peach, potato, corn leaf, melon aphids, and greenbug.
