ARTHROPODA From Eldredge (1991) INTRODUCTION Arthropods are the most diverse phylum today and probably also in the geologic past. They are a highly specialized group which are characterized by their bilaterally symmetrical body, paired appendages and a chitinous (calcite in some groups) exoskeleton. As the exoskeleton once produced remains inert, arthropods must periodically shed their exoskeleton during molting and re-precipitate a larger one in order to accommodate their larger size. Many arthropods may be familiar to you such as crabs, lobsters, barnacles, and insects, yet the fossil record of the phylum is dominated by few groups, particularly the trilobites, and to a lesser extent the eurypterids, and ostracodes. The trilobites in particular are unparalleled for their biostratigraphic utility for Cambrian and Ordovician and to a lesser extent Devonian sediments. Conversely, the eurypterids and ostracodes are more useful in determining ancient environments at least during mid to latter Paleozoic times.

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. In order to grow, arthropods must periodically molt a process that entails shedding their exoskeleton and inflating their body before the new skeleton hardens. The incredible diversity and success of the arthropods can be attributed to their extraordinarily adaptable body plan. A key feature is the evolution of the myriad types of appendages (antennae, claws, wings, shields, mouth parts) that allow arthropods to exploit nearly every niche on Earth.

Crustaceans - Phylum Arthropoda (Subphylum Crustacea) Species Home Introduced Species The Arthropods are the largest phylum of free living animals, including millions of species. The Subphylum Crustacea are a large group of mainly marine species. They differ from other arthropods by having two pairs of antennae in front of the mouth. About 40 000 species have been named, however this represents only a small proportion of the total (likely to be more than 100 000 species). The body has a basic plan, being subdivided into head, thorax and abdomen. Quite often, some of the thoracic segments are fused to the head, forming the carapace. Most crustacean groups have a planktonic larval stage that differs greatly in appearance to the adult. The most common larval form is a nauplius, a rounded animal with three pairs of appendages, including large antennae. Crustaceans occur in virtually all marine and most freshwater environments. They range in size from copepods (usually less than 1 mm) to crabs with a maximum leg span of more than 2 m.

PHYLUM ARTHROPODA The Crayfish Crayfish are found in streams, rivers, lakes and ponds where the water contains adequate amounts of calcium salts. They are primarily nocturnal, hiding in crevices and under rocks during the day and emerging to feed at night. They will eat almost anything organic - plant or animal, living or dead. The dissection of the crayfish requires a great deal of care. Be certain to follow instructions carefully and to ask for assistance if you are in doubt about any part of the procedure. Obtain a preserved crayfish and place it in your dissecting pan . The body is divided into an anterior cephalothorax (fused head and thorax) and a posterior abdomen (see Figure 6). The chitinous exoskeleton protects the crayfish from predators. The carapace is a saddlelike covering over the cephalothorax. A transverse groove separates the fused head from the thoracic region. The rostrum is an anterior, pointed extension of the head. The abdomen consists of several segments and is terminated by the telson. Examine the appendages. The appendages are modified to serve a variety of functions: feeding, walking and swimming. Although male and female crayfish have an equal number of appendages, in male crayfish the appendages joining the thorax have been modified. They are elongate and can be brought together to form a troughlike channel, used for the transfer of sperm from the male to the seminal receptacles of the female. Use Figure 6 to assist you in determining if your specimen is a male or a female.

RIGHT: The white cicada was folded by, and belongs to, Paul Close . Shown by permission. LEFT: The butterfly has very tiny legs; but it is straightforward to make if you have a fine enough grasp (or tweezers). CENTER: The dragonfly is made from the eagle base. LEFT: The caterpillar is a young butterfly. Its legs are even tinier than the butterfly's legs. LEFT: The asparagus beetle is a voracious pest. CENTER: The grasshopper has many sink folds. RIGHT: The preying mantis requires 100 steps, all of which are on-line. LEFT: The tarantula is fairly straightforward to make. It starts with a 1x1.5 paper, and ends with many small, thick folds. Personally, I think it looks more like a black widow than a hairy tarantula. CENTER: The lobster just requires sharp, accurate folding.

The arthropods include crustaceans insects centipedes millipedes , symphylans, pauropodans, and the extinct trilobites . Arthropods are characterized by a segmented body covered by a jointed external skeleton (exoskeleton), with paired jointed appendages on each segment; a complex nervous system with a dorsal brain, connective nerves passing around the anterior end of the digestive tract, and a ventral nerve cord with a ganglion in each body segment; an open circulatory system with a dorsal heart into which blood flows through paired openings (ostia); and a greatly reduced body cavity (coelom). Because the jointed exoskeleton blocks growth of the organism, it must be shed periodically. This phenomenon, called molting, or ecdysis, is a characteristic feature of the phylum; it permits rapid growth in size and significant change in body form until the new exoskeleton, secreted by the animal, has hardened. Arthropods are mainly terrestrial, but aquatic representatives are well known. There are three subphyla, comprising nine classes.
