Zoology Zoology The Academy of Natural Sciences in Philadelphia was founded in 1812 to expand knowledge of the natural world. In its early days it organized expeditions to explore the western part of the country, led by Stephen Long and Ferdinand Hayden. The Academy employed some of the leading zoologists of the day, including Thomas Say and Thomas Nuttall. ...more on Wikipedia about "Academy of Natural Sciences"
Acarology is the study of mites and ticks, the animals in the order Acarina. The name comes from the Greek akari, a type of mite, and -ology ("study of"). It is a subfield of zoology. ...more on Wikipedia about "Acarology"
Aeroplankton is the term used to describe the tiny lifeforms which float and drift in the air, carried by the current of the wind; it is the atmospheric analogue to oceanic plankton. ...more on Wikipedia about "Aeroplankton"
An alpha male or alpha female is the individual in the community whom the others follow and defer to. Chimpanzees, show deference to the alpha of the community by ritualized gestures such as bowing, allowing the alpha to walk first in a procession, or standing aside when the alpha challenges. Canines also show deference to the alpha pair in their pack, by allowing them to be the first to eat and, usually, the only pair to mate. Wolves are a well known example of this. ...more on Wikipedia about "Alpha (biology)"
The hard, rigid outer calcium carbonate covering of certain animals is called a shell. While many animals, particularly those that live in the sea, produce exoskeletons, usually only those of mollusks are considered to be shells. It is sometimes erroneously claimed that shells are made of chitin, but these are unrelated materials (except for their hardness and use as a covering by animals). ...more on Wikipedia about "Animal shell"
Animalcule is an older term for a microscopic animal or protozoan. Some better-known animalcules include: ...more on Wikipedia about "Animalcule"
Aposematism (from apo- away, and sematic warning), is a means of natural defence employing conspicuous colours or body parts by which an organism openly displays a warning signal to potential predators. The intent to become as noticeable as possible is the antithesis of the principles of natural camouflage. ...more on Wikipedia about "Aposematism" It's my www.shortopedia.com!
Appendiculata is a zoological name introduced by E. Ray Lankester (preface to the English edition of C. Gegenbaur's Comparative Anatomy), and employed by the same writer in the 9th edition of Encyclopaedia Britannica (article "Zoology") to denote the eighth phylum, or major division, of coelomate animals. The animals thus associated, the Rotifera, Chaetopoda and Arthropoda, are composed of a larger or smaller number of hollow rings, each ring possessing typically a pair of hollow lateral appendages, moved by intrinsic muscles and penetrated by blood-spaces. ...more on Wikipedia about "Appendiculata"
Arachnology is the scientific study of spiders and related organisms such as scorpions, pseudoscorpions, harvestmen, altogether called arachnids. However, the study of ticks and mites is sometimes not included in arachnology, but is called Acarology. ...more on Wikipedia about "Arachnology"
The term aschelminth is used for any member of about ten different invertebrate phyla. The Phylum Aschelminthes formerly included all of these phyla as subdivisions, but the term is no longer valid. It is now just a convenient word used to cover these organisms, most of which are microscopic soft-bodied worms. They are also called pseudocoelomates. ...more on Wikipedia about "Aschelminth"
The Asteriscus is the smaller of the two otoliths found in the inner ear of many fishes. ...more on Wikipedia about "Asteriscus"
Barophiles are bacteria which live in high pressure environments. They are generally found on ocean floors, where pressure generally exceeds 380 atm (38 MPa). Some have been found at the bottom of the Pacific Ocean where the maximum pressure is roughly 117 MPa. ...more on Wikipedia about "Barophile"
The beak - otherwise known as the bill - is the only device a bird has for consuming food. It is composed of an upper jaw called the maxilla, and the lower jaw called a mandible. ...more on Wikipedia about "Beak"
Behavioral ecology is the study of the ecological and evolutionary basis for animal behavior, and the roles of behavior in enabling an animal to adapt to its environment (both intrinsic and extrinsic). ...more on Wikipedia about "Behavioral ecology"
In zoology, Bergmann's Rule is a principle that correlates environmental temperature with body mass in warm-blooded animals. It asserts that within a species, the body mass increases with latitude and colder climate. Among mammals and birds, individuals of a particular species in colder areas tend to have greater body mass than individuals in warmer areas. For instance, White-tailed Deer are larger in Canada than in the Florida Keys. The rule is named after a nineteenth-century German biologist, Christian Bergmann. Bergmann's rule and Allen's rule are examples of clines frequently seen in mammals. ...more on Wikipedia about "Bergmann's Rule"
A bestiary, or Bestiarum vocabulum is a compendium of beasts. Bestiaries were made popular in the Middle ages in illustrated volumes that described various real or imaginary animals, birds and even rocks. The natural history and illustration of each beast were usually accompanied by a moral lesson. This reflected the belief that the world itself was literally the Word of God, and that every living thing had its own special meaning. For example, the pelican, which was believed to tear open its breast to bring its young to life with its own blood, was a living representation of Jesus. The bestiary, then, is also a reference to the symbolic language of animals in Western Christian art and literature. ...more on Wikipedia about "Bestiary"
A burrow is a hole or tunnel dug into the ground by an animal to create a space suitable for habitation, temporary refuge, or as a byproduct of locomotion. Burrows provide a form of shelter against predation and exposure to the elements. ...more on Wikipedia about "Burrow"
Cetology is the branch of marine mammal science that studies the approximately eighty species of whales, dolphins, and porpoise in the scientific order Cetacea. The term was coined in the mid-19th century from the Greek cetus ("whale") and -ology ("study"). ...more on Wikipedia about "Cetology"
In zoology, a chimera is an animal which has two or more different populations of cells, which are genetically distinct and which originated in different zygotes (fertilized eggs). It either is acquired through the infusion of allogeneic hematopoietic cells during transplantation or transfusion or it is inherited. In fraternal twins, chimerism occurs by means of blood-vessel anastomoses. Chimeras are named after the mythological creature Chimera. ...more on Wikipedia about "Chimera (genetics)"
The Cole Museum of Zoology forms part of the School of Animal and Microbial Sciences at the University of Reading and is located on the university's Whiteknights Campus in the town of Reading, England. ...more on Wikipedia about "Cole Museum of Zoology"
Conchiolin (sometimes referred to as conchin) and perlucin are complex proteins which are secreted by a mollusc's outer epithelium (the mantle) to form chambers which hold and bond to the crystals of aragonite which give such shells their stiffness. The ions necessary to form calcium carbonate are also secreted by the mantle, but it is the tailored ionic environment of the perlucin protein which causes aragonite (rather than calcite) crystals to nucleate ** , in much the same way that collagen nucleates hydroxyapatite crystals. Conchiolin serves as a relatively flexible, crack-deflecting matrix for the mineral aggregate particles; its strength and the strong bonding of perlucin give the finished material ( nacre) an impressive level of toughness. ...more on Wikipedia about "Conchiolin" Don't hesitate to contact stuff on www.shortopedia.com
Conchology is the collection and study of the shells of mollusks, a branch of malacology. ...more on Wikipedia about "Conchology"
Cryptozoology is the study of animals that are presumed (at least by the researcher) to exist, but for which conclusive proof is missing; the term also includes the study of animals generally considered extinct, but which are still occasionally reported. Those who study or search for such animals are called cryptozoologists, while the hypothetical creatures involved are referred to by some as "cryptids", a term coined by John Wall in 1983. ...more on Wikipedia about "Cryptozoology"
In zoology, deep-sea gigantism, also known as abyssal gigantism, is the tendency for species of crustaceans, invertebrates and other deep-sea dwelling animals to display a larger size than their shallow-water counterparts. Examples of this phenomenon include the Viperfish, Oarfish (up to 11 m), giant squid (up to 13 m) and the Colossal Squid which is estimated can grow up to 14 m in length. ...more on Wikipedia about "Deep-sea gigantism"
The term eggshell is the term for the outer covering of a hard-shelled egg, and some forms of eggs with soft outer coats. ...more on Wikipedia about "Eggshell"
