Public Aquarium
A public aquarium () or public water zoo is the aquatic counterpart of a zoo, which houses living aquatic animal and aquatic plant, plant specimens for public viewing. Most public aquariums feature tanks larger than those kept by home aquarists, as well as smaller tanks. Since the first public aquariums were built in the mid-19th century, they have become popular and their numbers have increased. Most modern accredited aquariums stress conservation issues and educating the public. History The first public aquarium was opened in London Zoo in May 1853; the ''Fish House'', as it came to be known, was constructed much like a greenhouse. P.T. Barnum quickly followed in 1856 with the first American aquarium as part of his established Barnum's American Museum, which was located on Broadway (Manhattan), Broadway in New York City before it burned down. In 1859, the Boston Aquarial Gardens, Aquarial Gardens were founded in Boston. A number of aquariums then opened in Europe, such as the ...

Male Whale Shark At Georgia Aquarium
Male (symbol: ♂) is the sex of an organism that produces the gamete (sex cell) known as sperm, which fuses with the larger female gamete, or ovum, in the process of fertilisation. A male organism cannot reproduce sexually without access to at least one ovum from a female, but some organisms can reproduce both sexually and asexually. Most male mammals, including male humans, have a Y chromosome, which codes for the production of larger amounts of testosterone to develop male reproductive organs. In humans, the word ''male'' can also be used to refer to gender, in the social sense of gender role or gender identity. Overview The existence of separate sexes has evolved independently at different times and in different lineages, an example of convergent evolution. The repeated pattern is sexual reproduction in isogamous species with two or more mating types with gametes of identical form and behavior (but different at the molecular level) to anisogamous species with gametes ...

Zoological Garden Of Hamburg
The Zoological Garden of Hamburg (German: ''Zoologischer Garten zu Hamburg'') was a zoo in Hamburg, Germany that operated from 1863 until 1930. Its aquarium, which opened in 1864, was among the first in the world. Founding In the 1850s, Hamburg was the third-largest city in the German Confederation; only Berlin and Vienna were larger. Trading in wild animals had begun in 1820 and a road-house menagerie was in operation in the 1840s. A wealthy merchant named Ernst von Merck, a member of parliament in the German government at Frankfurt am Main in 1848 and 1849, assembled a society for the purposes of creating a zoo. On 10 July 1860, at the charter meeting of the Zoological Society of Hamburg (German: ''Zoologische Gesellschaft in Hamburg''), Merck was selected as president. It was the fifth zoo in Germany, following the Berlin Zoological Garden in 1844, the Frankfurt Zoological Garden in 1858, the Cologne Zoological Garden in 1860 and the Dresden Zoo in 1861.

Cage (enclosure)
A cage is an enclosure often made of mesh, bars, or wires, used to confine, contain or protect something or someone. A cage can serve many purposes, including keeping an animal or person in captivity, capturing an animal or person, and displaying an animal at a zoo. Construction Since a cage is usually intended to hold living beings, at least some part of its structure must be such as to allow for the entry of light and air. Thus some cages may be made with bars spaced closely together for the intended captive to slip between them, or with windows covered by a mesh of some sort. Animal cages Cages often used to confine animals, and some are specially designed to fit a certain species of animal. One or more birds, rodents, reptiles, and even larger animals of certain breeds are sometimes confined in a cage as pets. Animal cages have been a part of human culture since ancient times. For example, an Ancient Greek vase dated to 490 B.C. depicts a boy holding a possibly do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aviary
An aviary is a large enclosure for confining birds, although bats may also be considered for display. Unlike birdcages, aviaries allow birds a larger living space where Bird flight, they can fly; hence, aviaries are also sometimes known as flight cages in the United Kingdom. Aviaries often contain plants and shrubbery to simulate a natural environment. Various types of aviary Large aviaries are often found in the setting of a zoo, zoological garden (for example, the London Zoo, the National Zoological Park (United States), National Zoo in Washington, D.C., and the San Diego Zoo). Walk-in aviaries also exist in bird parks, including the spacious Bird Paradise in Singapore, or the smaller Edward Youde Aviary in Hong Kong. Pittsburgh, Pennsylvania, Pittsburgh is home to the USA's National Aviary, perhaps the most prominent example in North America of an aviary not set inside a zoo. However, the oldest public aviary not set inside a zoo in North America, the Hamilton Aviary is locat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fish
A fish (: fish or fishes) is an aquatic animal, aquatic, Anamniotes, anamniotic, gill-bearing vertebrate animal with swimming fish fin, fins and craniate, a hard skull, but lacking limb (anatomy), limbs with digit (anatomy), digits. Fish can be grouped into the more basal (phylogenetics), basal jawless fish and the more common jawed fish, the latter including all extant taxon, living cartilaginous fish, cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break to the long tradition of grouping all fish into a single Class (biology), class (Pisces), modern phylogenetics views fish as a paraphyletic group. Most fish are ectotherm, cold-blooded, their body temperature varying with the surrounding water, though some large nekton, active swimmers like white shark and tuna can hold a higher core temperature. Many fish can communication in aquatic animals#Acoustic, communicate acoustically with each other, such as during courtship displays. The stud ...

Earless Seal
The earless seals, phocids, or true seals are one of the three main groups of mammals within the seal lineage, Pinnipedia. All true seals are members of the family Phocidae (). They are sometimes called crawling seals to distinguish them from the fur seals and sea lions of the family Eared seal, Otariidae. Seals live in the oceans of both hemispheres and, with the exception of the more tropical monk seals, are mostly confined to Polar region, polar, subpolar, and temperate climates. The Baikal seal is the only species of exclusively freshwater seal. Taxonomy and evolution Evolution The earliest known fossil earless seal is ''Noriphoca gaudini'' from the late Oligocene or earliest Miocene (Aquitanian (stage), Aquitanian) of Italy. Other early fossil phocids date from the mid-Miocene, 15 million years ago in the north Atlantic. Until recently, many researchers believed that phocids evolved separately from otariids and Walrus, odobenids; and that they evolved from otter-like ani ...

Bird
Birds are a group of warm-blooded vertebrates constituting the class (biology), class Aves (), characterised by feathers, toothless beaked jaws, the Oviparity, laying of Eggshell, hard-shelled eggs, a high Metabolism, metabolic rate, a four-chambered heart, and a strong yet lightweight Bird skeleton, skeleton. Birds live worldwide and range in size from the bee hummingbird to the common ostrich. There are over 11,000 living species and they are split into 44 Order (biology), orders. More than half are passerine or "perching" birds. Birds have Bird wing, wings whose development varies according to species; the only known groups without wings are the extinct moa and elephant birds. Wings, which are modified forelimbs, gave birds the ability to fly, although further evolution has led to the Flightless bird, loss of flight in some birds, including ratites, penguins, and diverse endemism, endemic island species. The digestive and respiratory systems of birds are also uniquely a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crust (geology)
In geology, the crust is the outermost solid shell of a planet, dwarf planet, or natural satellite. It is usually distinguished from the underlying mantle by its chemical makeup; however, in the case of icy satellites, it may be defined based on its phase (solid crust vs. liquid mantle). The crusts of Earth, Mercury, Venus, Mars, Io, the Moon and other planetary bodies formed via igneous processes and were later modified by erosion, impact cratering, volcanism, and sedimentation. Most terrestrial planets have fairly uniform crusts. Earth, however, has two distinct types: continental crust and oceanic crust. These two types have different chemical compositions and physical properties and were formed by different geological processes. Types of crust Planetary geologists divide crust into three categories based on how and when it formed. Primary crust / primordial crust This is a planet's "original" crust. It forms from solidification of a magma ocean. Toward the end o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Earth
Earth is the third planet from the Sun and the only astronomical object known to Planetary habitability, harbor life. This is enabled by Earth being an ocean world, the only one in the Solar System sustaining liquid surface water. Almost all of Earth's water is contained in its global ocean, covering Water distribution on Earth, 70.8% of Earth's crust. The remaining 29.2% of Earth's crust is land, most of which is located in the form of continental landmasses within Earth's land hemisphere. Most of Earth's land is at least somewhat humid and covered by vegetation, while large Ice sheet, sheets of ice at Polar regions of Earth, Earth's polar polar desert, deserts retain more water than Earth's groundwater, lakes, rivers, and Water vapor#In Earth's atmosphere, atmospheric water combined. Earth's crust consists of slowly moving tectonic plates, which interact to produce mountain ranges, volcanoes, and earthquakes. Earth's outer core, Earth has a liquid outer core that generates a ...

Education
Education is the transmission of knowledge and skills and the development of character traits. Formal education occurs within a structured institutional framework, such as public schools, following a curriculum. Non-formal education also follows a structured approach but occurs outside the formal schooling system, while informal education involves unstructured learning through daily experiences. Formal and non-formal education are categorized into levels, including early childhood education, primary education, secondary education, and tertiary education. Other classifications focus on teaching methods, such as teacher-centered and student-centered education, and on subjects, such as science education, language education, and physical education. Additionally, the term "education" can denote the mental states and qualities of educated individuals and the academic field studying educational phenomena. The precise definition of education is disputed, and there are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alfred Brehm
Alfred Edmund Brehm (; 2 February 1829 – 11 November 1884) was a German zoologist and writer. His multi-volume book '' Brehms Tierleben'', which he co-authored with Eduard Pechuël-Loesche, Wilhelm Haacke, and Richard Schmidtlein, became a household word for popular zoological literature. He was the first director of the Zoological Garden of Hamburg. Early life Brehm grew up in the small Thuringian village of Unter renthendorf as the son of the pastor Christian Ludwig Brehm, and of his second wife Bertha née Reiz. Christian Ludwig Brehm made a name for himself as an ornithologist by publications and through an extensive collection of stuffed birds. The collection, held in the parsonage and consisting of over 9,000 dead birds, offered a glimpse into the world of European birds. As a boy he helped expand his father by collecting specimens and became an excellent marskman. His father's research gave the younger Brehm an interest in zoology, but at first he wanted to be ...
