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.

Nighthawks are birds of the nightjar family in the New World subfamily Chordeilinae. They are medium-sized nocturnal birds with long wings, short legs and very short bills that usually nest on the ground and catch flying insects. The Least Nighthawk, at 16 cm (6.3 inches) and 23 grams, is the smallest of all Caprimulgiformes. Nightjars are sometimes referred to as goatsuckers from the mistaken belief that they suck milk from goats (the Latin for goatsucker is Caprimulgus).

The Swamp Sparrow, Melospiza georgiana, is a medium-sized sparrow. Adults have streaked rusty and black upperparts with a grey breast, light belly and a white throat. They have a rust-coloured cap and wings. Their face is grey with a dark line through the eye. They have a short bill and fairly long legs. Their breeding habitat is marshes, including salt marshes, across eastern North America and central Canada. The bulky nest is attached to marsh vegetation, often with leaves arching over the top. On the central Atlantic coast, in the southern parts of their summer range, they are permanent residents. Other birds migrate to the southern United States.

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.

The chigoe flea (Tunga penetrans) is a parasitic arthropod found in tropical climates, especially South America and the West Indies. At 1 mm long, the chigoe flea is the smallest known flea. Breeding female chigoes burrow into exposed skin and lay eggs, causing intense irritation. After this point, the skin lesion looks like a 5 to 10 mm white spot with a central black dot, which are the flea's exposed hind legs, respiratory spiracles and reproductive organs.

The Screamers are a small family of birds, the Anhimidae.The three species occur only in South America, ranging from Venezuela to northern Argentina. They are large, bulky birds, with a small downy head, long legs and large feet which are only partially webbed. They have large spurs on their wings which are used in fights over mates and territorial disputes, these can break off in the breast of other screamers, and are regularly renewed.

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.

The ground squirrels are the members of the Sciuridae most closely related to the genus Marmota. They make up the tribe Marmotini in the large and mainly terrestrial squirrel subfamily Xerinae, and containing six living genera. The ground squirrel is especially renowned for its tendency to rise up on its hind legs. It does this whenever it senses nearby danger, or when it must see over tall grasses. The squirrel then curls its paws flat against its chest and sends a screeching call to warn other family members about the presence of predators

Hesperornis is an extinct genus of flightless aquatic birds that lived during the Santonian to Campanian sub-epochs of the Late Cretaceous (89-65 mya). Hesperornis were very large birds, reaching up to 2 meters (6.5 feet) in length. They had virtually no wings, swimming with powerful hind legs. Their toes were probably lobed rather than being webbed, as in today's grebes; like in these, the toes could rotate well, which is necessary to decrease drag in lobed feet but not in webbed ones such as in loons, where the toes are simply folded together.

Crinoids, also known as sea lilies or feather-stars, are marine animals that make up the class Crinoidea of the echinoderms (phylum Echinodermata). They live both in shallow water and in depths as great as 6,000 meters. Crinoids are characterized by a mouth on the top surface that is surrounded by feeding arms. They have a U-shaped gut, and their anus is located next to the mouth.

A gravity escapement uses a small weight or a weak spring to give an impulse directly to the pendulum. The earliest form consisted of two arms which were pivoted very close to the suspension spring of the pendulum with one arm on each side of the pendulum. Each arm carried a small dead beat pallet with an angled plane leading to it. When the pendulum lifted one arm far enough its pallet would release the escape wheel. Almost immediately another tooth on the escape wheel would start to slide up the angle face on the other arm thereby lifting the arm. It would reach the pallet and stop. The other arm meanwhile was still in contact with pendulum and coming down again to a point lower than it had started from. This lowering of the arm provides the impulse to the pendulum. The design was developed steadily from the middle of the 18th century to the middle of the 19th century. It eventually became the escapement of choice for turret clocks.

Coccinellidae is a family of beetles, known variously as ladybirds (British English, Australian English, South African English), ladybugs (North American English) or lady beetles (preferred by some scientists). Lesser-used names include ladyclock, lady cow, and lady fly. The family name comes from its type genus, Coccinella. Coccinellids are found worldwide, with over 5,000 species described, more than 450 native to North America alone. Coccinellids are small insects, ranging from 1 mm to 10 mm (0.04 to 0.4 inches), and are commonly yellow, orange, or scarlet with small black spots on their wing covers, with black legs, head and antennae. A very large number of species are mostly or entirely black, gray, or brown and may be difficult for non-entomologists to recognize as coccinellids (and, conversely, there are many small beetles that are easily mistaken as such, like tortoise beetles).
