The Colorado potato beetle (Leptinotarsa decemlineata), also known as the Colorado beetle, ten-striped spearman, the ten-lined potato beetle) is an important pest of potato crops. It is approximately 10 mm (0.4 inches) long, with a bright yellow/orange body and 5 bold brown stripes along the length of each of its elytra, and it can easily be confused with its close cousin and look-alike, the false potato beetle. The beetle was described in 1824 by Thomas Say from specimens collected in the Rocky Mountains on buffalo-bur, Solanum rostratum. The origin of the beetle is somewhat unclear, but it seems to be that Colorado and Mexico are a part of its native distribution in the southwestern North America

Crickets, family Gryllidae (also known as "true crickets"), are insects somewhat related to grasshoppers and more closely related to katydids or bush crickets (family Tettigoniidae). They have somewhat flattened bodies and long antennae. There are about 900 species of crickets. They tend to be nocturnal and are often confused with grasshoppers because they have a similar body structure including jumping hind legs.

Orgyia leucostigma, the White-marked tussock moth, is a moth in the family Lymantriidae. The caterpillar is very common especially in late summer in eastern North America, as far west as Texas, Colorado, and Alberta. There are two or more generations a year in eastern North America (Wagner 2005). They overwinter in the egg stage. Eggs are laid in a single mass over the cocoon of the female, and covered in a froth (Wagner 2005). Up to 300 eggs are laid at a time. he larvae are brightly coloured, with tufts of hair-like setae. The head is bright red, the body has yellow or white stripes, with a black stripe along the middle of the back. There are bright red defensive glands on the hind end of the back. Four white toothbrush-like tufts stand out from the back, and there is a grey-brown hair pencil at the hind end. Touching the hairs will set off an allergic reaction in many humans (Wagner 2005). Young larvae skeletonize the surface of the leaf, while older larvae eat everything except the larger veins (Rose and Lindquist, 1982). They grow to about 35 mm.

Centipedes are arthropods belonging to the class Chilopoda and the Subphylum Myriapoda. They are elongated metameric animals with one pair of legs per body segment. A key trait uniting this group is a pair of venom claws or forcipules formed from a modified first appendage. This also means that centipedes are an exclusively predatory taxon, which is uncommon.

An illustration of Cochineal living on cactus. Cochineal is the name of both crimson or carmine dye and the cochineal insect (Dactylopius coccus), a scale insect in the suborder Sternorrhyncha, from which the dye is derived. This type of insect, a primarily sessile parasite, lives on cacti from the genus Opuntia, feeding on moisture and nutrients in the cacti. The insect produces carminic acid which deters predation by other insects. Carminic acid can be extracted from the insect's body and eggs to make the dye. Cochineal is primarily used as a food colouring and for cosmetics.

An illustration of a dragon fly (right) and a nymph (left). A dragonfly is a type of insect belonging to the order Odonata, the suborder Epiprocta or, in the strict sense, the infraorder Anisoptera. It is characterized by large multifaceted eyes, two pairs of strong transparent wings, and an elongated body. Dragonflies are similar to damselflies, but the adults can be differentiated by the fact that the wings of most dragonflies are held away from, and perpendicular to, the body when at rest. n biology, a nymph is the immature form of some insects, which undergoes incomplete metamorphosis (hemimetabolism) before reaching its adult stage; unlike a typical larva, a nymph's overall form already resembles that of the adult. In addition, while a nymph moults it never enters a pupal stage. Instead, the final moult results in an adult insect.

The American Harpy Eagle (Harpia harpyja) is a neotropical eagle, often simply called the Harpy Eagle. It is the only member of the genus Harpia. It is the largest and most powerful raptor found in the Americas, usually inhabiting tropical lowland rainforests in the upper (emergent) canopy layer. Its name references the harpies from Ancient Greek mythology. These were wind spirits that took the dead to Hades, and were said to have a body like an eagle and the face of a human.

An illustration of an earthworm. The basic body plan of an earthworm is a tube, the digestive system, within a tube, the muscular outer body. The body is annular, formed of segments that are most specialized in the anterior. Earthworms have a simple circulatory system. They have two main blood vessels that extend through the length of their body: a ventral blood vessel which leads the blood to the posterior end, and a dorsal blood vessel which leads to the anterior end. Most earthworms are decomposers feeding on undecayed leaf and other plant matter, others are more geophagous.

The Common Eider, Somateria mollissima, is a large (50-71cm body length) sea-duck, which is distributed over the northern coasts of Europe, North America and eastern Siberia. It breeds in Arctic and some northern temperate regions, but winters somewhat farther south in temperate zones, when it can form large flocks on coastal waters. The eider's nest is built close to the sea and is lined with the celebrated eiderdown, plucked from the female's breast. This soft and warm lining has long been harvested for filling pillows and quilts, but in more recent years has been largely replaced by down from domestic farm-geese and synthetic alternatives.

A lynx is any of four medium-sized wild cats. All are members of the genus Lynx, but there is considerable confusion about the best way to classify felids at present, and some authorities classify them as part of the genus Felis. The Caracal, despite sometimes being called Persian Lynx or African Lynx, does not belong to this genus. Lynx have short tails and characteristic tufts of black hair on the tip of the ears. They have a ruff under the neck, which has black bars (not very visible), resembling a bow tie. They have large paws padded for walking on snow and long whiskers on the face. The body color varies from medium brown to gold-ish to beige-white; and occasionally, is marked with dark brown spots, especially on the limbs. All species of lynx also have white fur on their chests, bellies and on the insides of their legs which are extensions of the chest and belly fur. Also, the lynx's coloring, fur height and paw size varies by its climate range- in the Southwest US, the fur and color are short-haired, dark and the paws are smaller and less padded, as the lynx ranges to its colder Northern climes, the fur gets progressively thicker (for warmth), the color gets lighter (for camouflage) and its paws enlarge and become more padded for snowy environments.

Flounder (also; fluke) are flatfish that live in ocean waters ie., Northern Atlantic and waters along the east coast of the United States and Canada, and the Pacific Ocean, as well. While flounders have both eyes situated on one side of the head, they are not born this way. Their life involves metamorphosis. During metamorphosis, one eye migrates to the other side of the body so that both eyes are situated on the upward-facing side of its body. After metamorphosis, flounder lie on one side on the ocean floor; either the left or right side might face upward depending on the species.

An illustration of a fossil containing Chirotherium tracks. Chirotherium (also known as Cheirotherium) or 'hand-beast', is the name of a creature which may be known only from fossil imprints of its tracks (trace fossils). These look, by coincidence, remarkably like the hand of an ape/human or bear, with the outermost toe having evolved to extend out to the side like a thumb, although probably only providing a firmer grip in mud. Its tracks were first found in 1834, in red sandstone in Thuringia, Germany, dating from 240 million years ago (mya). This creature was probably an archosaur, related to the ancestors of the dinosaurs.

An interior view of a sea cucumber. The sea cucumber (also known as trepang, b&ecirc;che-de-mer, balate, or ambiguously, sea slug) is an echinoderm of the class Holothuroidea, with an elongated body and leathery skin, which is found on the sea floor worldwide. It is also named because of its cucumber-like shape. The body contains a single, branched gonad. Like all echinoderms, sea cucumbers have an endoskeleton just below the skin, calcified structures that are usually reduced to isolated microscopic ossicles (or sclerietes) joined by connective tissue.

An illustration of a small jellyfish. Jellyfish are free-swimming members of the phylum Cnidaria. ellyfish don't have specialized digestive, osmoregulatory, central nervous, respiratory, or circulatory systems. They digest using the gastrodermal lining of the gastrovascular cavity, where nutrients are absorbed. They do not need a respiratory system since their skin is thin enough that the body is oxygenated by diffusion. They have limited control over movement and mostly free-float, but can use the hydrostatic skeleton of the water pouch to accomplish vertical movement through pulsations of the disc-like body.

An illustration of: 1, Coralla cut open showing the four stamens; 2, Unripe fruit (lengthwise); 3, ripe capsule split open; and the foxglove plant. Digitalis is a genus of about 20 species of herbaceous perennials, shrubs, and biennials that are commonly called foxgloves. The genus was traditionally placed in the figwort family Scrophulariaceae, but upon review of phylogenetic research, it has now been placed in the much enlarged family Plantaginaceae. The genus is native to Europe, western and central Asia, and northwestern Africa. The scientific name means "finger-like" and refers to the ease with which a flower of Digitalis purpurea can be fitted over a human fingertip. The flowers are produced on a tall spike, are tubular, and vary in colour with species, from purple to pink, white, and yellow. The best-known species is the Common Foxglove, Digitalis purpurea. It is a biennial, often grown as an ornamental plant due to its showy flowers, that range in colour from purples through to whites, with variable marks and spotting. The first year of growth produces only the long, basal leaves. In the second year, the erect leafy stem 0.5-2.5 m tall develops.

The velvet crab (alternatively velvet swimming crab or devil crab) is the largest swimming crab found in British coastal waters, with a carapace width of up to 100 mm. The body is coated with short hairs, giving the animal a velvety texture, hence the common name. It is one of the major crab species for UK fisheries. The velvet crab lives from southern Norway to Western Sahara in the North Sea and north Atlantic as well as western parts of the Mediterranean Sea, on rocky bottoms from the shoreline to a depth of about 65 m. The last pair of pereiopods are flattened to facilitate swimming.

Hermit crabs are decapod crustaceans of the superfamily Paguroidea. They are not closely related to true crabs. Hermit crabs are quite commonly seen in the intertidal zone, for example in tide pools. Most species of hermit crabs have long soft abdomens which are protected from predators by the adaptation of carrying around a salvaged empty seashell, into which the whole crab's body can retract. Most frequently hermit crabs utilize the shells of sea snails, marine gastropod mollusks. The tip of the hermit crab's abdomen is adapted to clasp strongly onto the columella of the snail shell. As the hermit crab grows in size, it has to find a larger shell and abandon the previous one.

The Sumerian word lama, which is rendered in Akkadian as lamassu, refers to a beneficient protective female deity. The corresponding male deity was called alad, in Akkadian, &scaron;&ecirc;du. In art they were depicted as hybrids, as winged bulls or lions with the head of a human male (Centauroid). There are still surviving figures of &scaron;&ecirc;du in bas-relief and some statues in museums. Notable examples of &scaron;&ecirc;du/lamassu held by museums include those at the British Museum, Mus&eacute;e du Louvre, National Museum of Iraq, Metropolitan Museum of Art and one extremely large example kept at the Oriental Institute, Chicago. They are generally attributed to the ancient Assyrians.
