Lunule (bivalve)
A lunule (from the Latin meaning small moon or crescent moon) is an anatomical feature which is found in the exterior surface of the shells of some species of clams, bivalve mollusks, as for example in the family Veneridae and in the genus '' Ascetoaxinus''. The lunule is a well-defined area near the hinge line A hinge line is an imaginary longitudinal line along the dorsal edge of the shell of a bivalve mollusk where the two valves hinge or articulate. The hinge line can easily be perceived in these images of a mussel shell and an ark shell.Invertebrat ... of the shell, anterior to the beaks.

Gold Lunula
The Gold lunula (plural: lunulae) is a distinctive type of late Neolithic, Chalcolithic or (most often) early Bronze Age necklace or collar shaped like a crescent moon; most are from Prehistoric Ireland. They are normally flat and thin, with roundish spatulate terminals that are often twisted to 45 to 90 degrees from the plane of the body. Gold lunulae fall into three distinct groups, termed Classical, Unaccomplished and Provincial by archaeologists. Most have been found in Ireland, but there are moderate numbers in other parts of Europe as well, from Great Britain to areas of the continent fairly near the Atlantic coasts. Although no lunula has been directly dated, from associations with other artefacts it is thought they were being made sometime in the period between 2400–2000 BC; a wooden box associated with one Irish find has recently given a radiocarbon dating range of 2460–2040 BC. Of the more than a hundred gold lunulae known from Western Europe, more than eighty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lunula (amulet)
A ''lunula'' (plural: ''lunulae'') was a crescent moon shaped pendant worn by girls in ancient Rome. Girls ideally wore them as an apotropaic amulet, the equivalent of the boy's bulla. In the popular belief the Romans wore amulets usually as a talisman, to protect themselves against evil forces, demons and sorcery, but especially against the evil eye. In Plautus' play, Epidicus asks the young girl Telestis: "Don't you remember my bringing you a gold lunula on your birthday, and a little gold ring for your finger?" An explicit definition is provided by Isidore of Seville: "Lunulae are female ornaments in the likeness of the moon, little hanging gold bullae." But in Plautus' play ''Rudens'', Palaestra says her father gave her a golden bulla on the day of her birth.

Lunula (anatomy)
The lunula, or lunulae (pl.) (), is the crescent-shaped whitish area of the bed of a fingernail or toenail. In humans, it appears by week 14 of gestation, and has a primary structural role in defining the free edge of the distal nail plate (the part of the nail that grows outward). Appearance It is located at the end of the nail (that is closest to the skin of the finger), but it still lies under the nail. It is not actually white but only appears so when it is seen through the nail. Outlining the nail matrix, the lunula is a very delicate part of the nail structure. If one damages the lunula, the nail will be permanently deformed. Even when the totality of the nail is removed, the lunula remains in place and is similar in appearance to another smaller fingernail embedded in the nail bed. In most cases, it is half-moon-shaped and has unique histologic features. Examinations concluded that the lunula is an area of loose dermis with lesser developed collagen bundles. It appears ...

Bracket
A bracket is either of two tall fore- or back-facing punctuation marks commonly used to isolate a segment of text or data from its surroundings. Typically deployed in symmetric pairs, an individual bracket may be identified as a 'left' or 'right' bracket or, alternatively, an "opening bracket" or "closing bracket", respectively, depending on the directionality of the context. Specific forms of the mark include parentheses (also called "rounded brackets"), square brackets, curly brackets (also called 'braces'), and angle brackets (also called 'chevrons'), as well as various less common pairs of symbols. As well as signifying the overall class of punctuation, the word "bracket" is commonly used to refer to a specific form of bracket, which varies from region to region. In most English-speaking countries, an unqualified word "bracket" refers to the parenthesis (round bracket); in the United States, the square bracket. Various forms of brackets are used in mathematics, with s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sand Dollar
Sand dollars (also known as a sea cookie or snapper biscuit in New Zealand, or pansy shell in South Africa) are species of flat, burrowing sea urchins belonging to the order Clypeasteroida. Some species within the order, not quite as flat, are known as '' sea biscuits''. Sand dollars can also be called "sand cakes" or "cake urchins". Anatomy Sand dollars are small in size, averaging from three to four inches. As with all members of the order Clypeasteroida, they possess a rigid skeleton called a test. The test consists of calcium carbonate plates arranged in a fivefold symmetric pattern. The test of certain species of sand dollar have slits called lunules that can help the animal stay embedded in the sand to stop it from being swept away by an ocean wave. In living individuals, the test is covered by a skin of velvet-textured spines which are covered with very small hairs (cilia). Coordinated movements of the spines enable sand dollars to move across the seabed. The velvety ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chaetodon Lunula
The raccoon butterflyfish (''Chaetodon lunula''), also known as the crescent-masked butterflyfish, lunule butterflyfish, halfmoon butterflyfish, moon butterflyfish, raccoon butterfly, raccoon, raccoon coralfish, and redstriped butterflyfish, is a species of marine ray-finned fish, a butterflyfish belonging to the family Chaetodontidae. It is found in the Indian and Pacific Oceans. Taxonomy ''Chaetodon lunula'' was first formally described as ''Pomacentrus lunula'' in 1802 by the french naturalist Bernard Germain de Lacépède (1756-1825) with the type locality given as "the Indian Ocean". It belongs to the large subgenus ''Rabdophorus'' which might warrant recognition as a distinct genus. In this group, its closest relative is probably the very similar Red Sea raccoon butterflyfish or diagonal butterflyfish, ''C. fasciatus''. Other close relatives appear to be the black butterflyfish, '' C. flavirostris''), Philippine butterflyfish, ''C. adiergastos'', and perhaps also t ...
