An illustration of Biscayne Bay, is a lagoon that is approximately 35 miles (56 km) long and up to 8 miles (13 km) wide located on the Atlantic coast of south Florida. It is usually divided for purposes of discussion and analysis into three parts, North Bay, Central Bay and South Bay. North Bay separates Miami Beach on its barrier island from Miami on the mainland. It has been severely affected over the last century by raw sewage releases, urban runoff, shoreline bulkheading, dredging, the creation of artificial islands and the loss of natural fresh water flow into the bay. North Bay accounts for only 10% of the water area of the bay. Central Bay is the largest part of the bay. It is separated from the Atlantic Ocean by the Safety Valve, a series of shallow flats separated by tidal flow channels, stretching from the south end of Key Biscayne to the Ragged Keys at the north end of the Florida Keys. It has been adversely affected primarily by bulkheading, urban runoff discharged by canals, and the loss of natural fresh water flow. South Bay is nearly as large as Central Bay, and is the least affected by human activities, although it also suffers from the loss of natural fresh water flow. South Bay is separated from the Atlantic Ocean by the northernmost of the Florida Keys, and is connected to Florida Bay through channels and "sounds" lying between the mainland and the keys.

The Shedu is a celestial being from Mesopotamian mythology. He is a human above the waist and a bull below the waist. He also has the horns and the ears of a bull. The bull man helps people fight evil and chaos. He holds the gates of dawn open for the sun god Shamash and supports the sun disc. He is often shown on Cylinder Seals. It appears frequently in Mesopotamian art, sometimes with wings. Statues of the bull-man were often used as gatekeepers.

Watercresses are fast-growing, aquatic or semi-aquatic, perennial plants native from Europe to central Asia, and one of the oldest known leaf vegetables consumed by human beings. These plants are members of the Family Brassicaceae or cabbage family, botanically related to garden cress and mustard — all noteworthy for a peppery, tangy flavor.

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.

The Monument marks the grave site of the bones of victims of the Wyoming Massacre, which took place on July 3, 1778. Local residents banded together to defend the area against an invasion of British Tories as well as pro-Tory Native Americans. The battle ended in defeat for the colonial fighters and considerable brutality followed the actual Battle. In 1833, the bones were reinterred in a vault under the present Monument. The monument is located in the borough of Wyoming, Pennsylvania.

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.

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.

Corystes cassivelaunus, the masked crab, helmet crab or sand crab, is a burrowing crab of the North Atlantic and North Sea from Portugal to Norway, which also occurs in the Mediterranean Sea. It may grow up to 4 cm long (carapace length). The name "masked crab" derives from the patterns on the carapace which resemble a human face, in a similar manner to heikegani.

In 1959 an international donations campaign to save the monuments of Nubia began: the southernmost relics of this ancient human civilization were under threat from the rising waters of the Nile that were about to result from the construction of the Aswan High Dam. This image gives a perspective view of the entrance hall, in which are seen eight standing colossal statues 33 feet high, supported by square piers.1

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, šêdu. 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 šêdu in bas-relief and some statues in museums. Notable examples of šêdu/lamassu held by museums include those at the British Museum, Musée 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.
