An illustration of a simple five armed crinoid with a detailed view of the tegmen of five orals. 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.

An diagram of the anatomy of a sea urchin. Sea urchins are small, globular, spiny sea creatures, composing most of class Echinoidea. They are found in oceans all over the world. Their shell, or "test", is round and spiny, typically from 3 to 10 cm across. Common colors include black and dull shades of green, olive, brown, purple, and red. They move slowly, feeding mostly on algae. Sea otters, wolf eels, and other predators feed on urchins. Sea urchins are harvested and served as a delicacy.

A dorsal view of a chiton, showing the eight shell plates. Chitons are small to large, primitive marine mollusks in the class Polyplacophora. There are 900 to 1,000 extant species of chitons in the class, which was formerly known as Amphineura. Chitons have a shell which is composed of eight separate shell plates or valves. These plates overlap somewhat at the front and back edges, and yet the plates articulate well with one another. Because of this, although the plates provide good protection for impacts from above, they nonetheless permit the chiton to flex upward when needed for locomotion over uneven surfaces, and also the animal can slowly curl up into a ball when it is dislodged from the underlying surface. The shell plates are surrounded by a structure known as a girdle.

Flamingos are gregarious wading birds in the genus Phoenicopterus and family Phoenicopteridae. They are found in both the Western Hemisphere and Eastern Hemisphere, but are more numerous in the former. There are four species in the Americas while two exist in the Old World. Two species, the Andean and the James's Flamingo, are often placed in the genus Phoenicoparrus instead of Phoenicopterus.

Jain caves reveal specific dimensions of Jain philosophy and tradition. They reflect a strict sense of asceticism &ndash; they are not relatively large as compared to others, but they present exceptionally detailed art works. The most remarkable Jain shrines are the <em>Chhota Kailash</em> (cave 30), the <em>Indra Sabha</em> (cave 32) and the <em>Jagannath Sabha</em> (cave 33). The <em>Indra Sabha</em> is a two storeyed shrine with a very fine carving of the lotus flower on the ceiling. In another cave, an imposing image of Ambika, the Yakshi (dedicated attendant deity) of Neminatha is found seated on her lion under a mango tree, laden with fruits. All other Jain caves are also characterized by intricate detailing. Many of the structures had rich paintings in the ceilings - fragments of which are still visible.

A pillar is similar to a column which is a vertical support structure in architecture, but the base section is any shape but circular. Tschultri, or choultry, is a resting place for visitors where rooms and food are provided by a charitable institution for nominal rates. Some were guest-houses where accommodation is free of charge. Choultries were famous in Colonial India. It was an Hindu-Caravanserai or a Colonnade. It was a typical ancient Indian type of hotel.

Luxor Temple is a large Ancient Egyptian temple complex located on the east bank of the River Nile in the city today known as Luxor (ancient Thebes) and was founded in 1400 <small>BC</small>. The temple properly begins with the 24 meter (79 ft) high First Pylon, built by Ramesses II. The pylon was decorated with scenes of Ramesses's military triumphs (particularly the Battle of Kadesh). Pylon is the Greek term for a monumental gateway of an Egyptian temple. It consists of two tapering towers, each surmounted by a cornice, joined by a less elevated section which enclosed the entrance between them.

Annual Honesty (Lunaria annua) is a tall (height about 1 m), hairy-stemmed biennial plant found throughout Europe, North America, and parts of Asia. It has large, pointed oval leaves with marked serrations. The common name "Honesty" arose in the 16th century, and it may be due to the translucent seed-pods which are like flattened pea-pods and borne on the plant through winter. In South-East Asia and elsewhere, it is called the Money Plant, because its seed pods have the appearance of silver coins. In the United States it may also be known as "Silver Dollars," also because of the seed pods.

The serious, solemn, and awe-inspiring efect which the general arrangement of the temple produces is maintained by the smaller details, while the slanting form of the outer walls gives the temple an appearance of solidity and isolation. On this account, and especially owing to its simple unbroken lines, the exterior although monotonous and heavy, is still imposing. The chief peculiarity in the construction of these buildings is that they produce the effect of being composed of an agglomeration of separate parts, which resemble on another, but become smaller and smaller towards the rear of the structure.
