The Colosseum or Coliseum, originally known as the Flavian Amphitheatre (Latin: Amphitheatrum Flavium), is the largest amphitheatre built in the Roman empire. Originally capable of seating 50,000 spectators, it was once used for gladiatorial combat. It was built in the 70s AD.

The Antarctic icefishes belong to the perciform suborder Notothenioidei and are the largely endemic, dominant fish taxa in the cold continental shelf waters surrounding Antarctica. At present, the suborder includes 8 families with 43 genera and 122 species. Although the Southern Ocean is relatively well sampled, new species of notothenioids are still being described.
The notothenioids all lack a swimbladder, and the majority of species are therefore benthic or demersal in nature. However, a depth-related diversification has given rise to some species attaining increased buoyancy, using lipid deposits in tissues and reduced ossification of bony structures.
The notothenioids are generally considered to be the only marine fish species flock.
Notothenioid fishes are able to survive in the freezing, ice-laden waters of the Southern Ocean because of the presence of an antifreeze glycoprotein in blood and body fluids.

The Parliament of the United Kingdom of Great Britain and Northern Ireland is the supreme legislative body in the United Kingdom and British overseas territories. It alone has parliamentary sovereignty. At its head is the Sovereign; it is bicameral, including an upper house, called the House of Lords, and a lower house, called the House of Commons. The House of Lords includes two different types of members: the Lords Spiritual (the senior bishops of the Church of England) and the Lords Temporal (members of the Peerage); it is a wholly unelected body. The House of Commons, on the other hand, is a democratically elected chamber. The House of Lords and the House of Commons meet in separate chambers in the Palace of Westminster (commonly known as the "Houses of Parliament"), in the British capital, London (more precisely, in the borough, and city, known as the City of Westminster). By constitutional convention, all government ministers, including the Prime Minister, are drawn exclusively from the House of Commons or House of Lords.
Parliament evolved from the ancient council that advised the Sovereign. In theory, power is vested not in Parliament, but in the "Queen-in-Parliament" (or "King-in-Parliament"). The Queen-in-Parliament is often said to be a completely sovereign authority, though such a position is debatable. In modern times, real power is vested in the democratically elected House of Commons; the Sovereign acts only as a figurehead and the powers of the House of Lords are greatly limited.
The British Parliament is often called the "Mother of Parliaments," as the legislative bodies of many nations; most notably, those of the members of the Commonwealth; are modelled on it. However, it is a misquotation of John Bright, who had actually remarked on 18 January 1865 that "England is the Mother of Parliaments", in the context of supporting demands for expanded voting rights in a country which had pioneered Parliamentary government.

The Spanish Iris (Iris xiphium) is an iris native to Spain. It is bulbous and bears handsome blue and yellow flowers, not so large as those of I. xipiodes. This species is also known as the Small Bulbous rooted Iris and many hybrids are known as Dutch Iris. The Spanish Iris is favoured by florists for its striking colour combinations.

Phytoplankton are microscopic plants that live in the ocean. There are many species of phytoplankton, each of which has a characteristicshape. Collectively, phytoplankton grow abundantly in oceans around the world and are the foundation of the marine food chain. Small fish, and some species of whales, eat them as food. Larger fish then eat the smaller fish. Humans catch and eat many of these larger fish. Since phytoplankton depend upon certain conditions for growth, they are a good indicator of change in their environment. For these reasons, and because they also exert a global-scale influence on climate, phytoplankton are of primary interest to oceanographers and Earth scientists around the world.
