Eagle rays feed on molluscs and crustaceans, crushing their shells with their flattened teeth, while devil rays and manta rays filter plankton from the water.
They are excellent swimmers and are able to breach the water up to several metres above the surface. Compared with other rays, they have long tails, and well-defined diamond-shaped bodies. They are ovoviviparous, giving birth to up to six young at a time. They range from to in length.
The tail looks like a whip and may be as long as the body. It is armed with a sting. Eagle rays live close to the coast in depths of 1 to 30 metres and in exceptional cases they are found as deep as 300 m. The eagle ray is commonly seen cruising along sandy beaches in very shallow waters.
In Nelson's "Fishes of the World", the eagle rays are a subfamily, and are joined by the manta rays and the eagle rays. As Nelson sees it, there are seven genera in the family, in three subfamilies. In our classification, the three groups are families in the suborder Myliobatoidei.
Glasgow Prestwick Airport
Glasgow Prestwick Airport is the second airport serving Glasgow. It also serves the Greater Glasgow area. It is northeast of the town of Prestwick in South Ayrshire. It is 32 miles from the city centre of Glasgow.
Prestwick is Scotland's largest airport by size. However, Edinburgh Airport, Glasgow International and Aberdeen Airport all handle more passengers. The year with the most passengers passing through Prestwick was 2007. Since 2007, a lot less passengers pass through Prestwick. 1.3 million passengers passed through the airport in 2011. This was 22% reduction from 2010.
Douglas Fowler McIntyre and the Duke of Hamilton owned the airport at first. These people were the first to fly a plane to the top of Mount Everest in 1933. During and after World War II it was a Royal Air Force base. In 1952 it was made a United States Air Force base.
The airport was made bigger in the early 1960s: the runway was made longer and a new terminal building was made. The new, bigger airport opened in 1964. Today, Glasgow Prestwick is mostly used by Ryanair.
On 8 March 2012, Infratil, the company which owns Prestwick, said that they had placed the airport up for sale. The Chief Executive Marco Bogoievski said that he does not regret selling the airport.
The Royal Navy Fleet Air Arm uses part of the airport. It has 3 Sea King helicopters there for search and rescue. They cover Ben Nevis, the Lakes, Northern Ireland and 200 NM (370 km; 230 mi) past the Irish coast. This force is often called 'HMS Gannet'. 15 officers, 11 ratings, 28 civil servants and 50 civilian staff work at the base.
Shamarpa
Shamarpa or more formally Kunzig Shamar Rinpoche is Tibetan Buddhis teacher. Together with Karmapa he is the second lineage holder of the Karma Kagyu school of Tibetan Buddhism. Shamarpa is regarded as manifestation of Amitabha Buddha. He also is the second lama who consciously incarnates in subsequent order of Buddhist teachers.
The first Shamar Rinpoche Khedrup Drakpa Senge (1284–1349) was the principal disciple of the 3rd Karmapa Rangjung Dorje.
The present (14th) Shamarpa is Mipham Chokyi Lodro, born in Derge, Tibet in 1952. At age four he was recognized by his uncle the 16th Karmapa.
Naropa
Nāropā (956–1041) was an Indian Buddhist teacher. He was the disciple of Tilopa and also brother and pupil of Niguma. Naropa was the main teacher of Marpa, the founder of the Kagyu school of Tibetan Buddhism.
Naropa was born a high status Brahmin and from an early age showed strong, highly intelligent mind. At the age of 28 Naropa entered the famous Buddhist University at Nalanda where he studied both Sutra and Tantra. He had the reputation of a great scholar and debater. Later Naropa became studend of Tilopa and spent twelve years with him. While studying and meditating with his teacher Naropa met and overcame twelve minor and twelve major hardships. Eventually he reached full realization and become teacher of Marpa.
Iodine deficiency
Iodine deficiency is when there is not enough iodine in the body. Iodine is an essential trace element. The thyroid hormones thyroxine and triiodotyronine have iodine. In areas where marine food is not eaten, there is low iodine in the diet. This causes iodine deficiency which gives rise to
goiter (so-called endemic goiter), as well as cretinism, which results in developmental delays and other health problems.
"The Lancet" has said, "According to WHO, in 2007, nearly 2 billion individuals had insufficient iodine intake, a third being of school age. ... Thus iodine deficiency, as the single greatest preventable cause of mental retardation, is an important public-health problem." Iodine deficiency causes diseases of the oral and salivary glands.
In these areas,small amounts of iodine to table salt in form of sodium iodide, potassium iodide, and/or potassium iodate is added. This helps preventing iodine deficiency. This product is known as "iodized salt". Iodine compounds have also been added to other foods. This includes flour, water and milk in areas of deficiency. Seafood is also a well known source of iodine. Thus, iodine deficiency is more common in mountainous regions of the world where food is grown in soil poor in iodine.

Trachea
The trachea, or windpipe, is the bony tube that connects the nose and mouth to the lungs, and is an important part of the vertebrate respiratory system. In mammals, the trachea begins at the lower part of the larynx and continues to the lungs, where it branches into the right and left bronchi. Inflammation of the trachea can lead to other conditions, such as tracheitis, which is the inflammation of the linings of the trachea.
The invertebrate trachea refers to the open respiratory system of terrestrial arthropods. It consists of spiracles, tracheae, and tracheoles that take metabolic gases to and from tissues. The distribution of spiracles varies, but in general each segment of the body has only one pair of spiracles, each of which connects to an atrium and has a relatively large tracheal tube behind it.
The smallest tubes, tracheoles, penetrate cells and diffuse water, oxygen, and carbon dioxide. Gas may be moved actively or by passive diffusion. Unlike vertebrates, insects do not generally carry oxygen in their haemolymph.
This is one of the factors that may limit their size.
A tracheal tube may contain ridge-like circumferential rings of taenidia in various geometries such as loops or helices. In the head, thorax, or abdomen, tracheae may also be connected to air sacs. Many insects, such as grasshoppers and bees, which actively pump the air sacs in their abdomen, are able to control the flow of air through their body. In some aquatic insects, the tracheae exchange gas through the body wall directly, in the form of a gill, or function as normal, via a plastron. Despite being internal, the tracheae of arthropods are shed during moulting (ecdysis).
