This greeting consists of the couple swimming together and entwining their bodies in a loving embrace. It must work well because these fish form monogamous couples, often staying together for life. When male horseshoe crabs find a suitable female they grab hold of her to guard her from other males. A male will stay attached to a female for months on end hoping that she will release eggs for him to fertilize. Little does the male know, she will only release her eggs in the same area where she herself was hatched.
It could be a long wait. A male mantis shrimp is an expert fisherman. Using a powerful club-like appendage he will strike out and stun unsuspecting fish swimming by. He supplies his mate with food so she can use her energy to produce offspring. Often times the male is solely responsible for providing the food and in the event of his death the female will starve.
She then continued her studies at the University of British Columbia where she studied the physiology of fishes and received a Master of Science degree in Zoology.

References Munk's Ro. Lolium temulentum, typically known as darnel, poison darnel, darnel ryegrass or cockle, is an annual plant of the genus Lolium within the family Poaceae. The plant stem can grow up to one meter tall, with inflorescence in the ears and purple grain. It has a global distribution. Growth Habitus Darnel usually grows in the same production zones as wheat and was a serious weed of cultivation until modern sorting machinery enabled darnel seeds to be separated efficiently from seed wheat.
The spikes of L. The spikelets are oriented edgeways to the rachis and have only a single glume, while those of wheat are oriented with the flat side to the rachis and have two glumes.

Wheat will appear brown when ripe, whereas darnel is black. Ficus carica is an Asian species of flowering plant in the mulberry family, known as the common fig or just the fig. It is the source of the fruit also called the fig and as such is an important crop in those areas where it is grown commercially. Native to the Middle East and western Asia, it has been sought out and cultivated since ancient times and is now widely grown throughout the world, both for its fruit and as an ornamental plant. The name of the caprifig Ficus caprificus Risso is derived both from Latin capro referring to billygoat and from English fig.
The — Republic of Venice was a major financial and maritime. Animals are multicellular eukaryotic organisms that form the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and grow from a hollow sphere of cells, the blastula, during embryonic development.
Over 1. Animals range in length from 8. The category includes humans, but in colloquial use the term animal often refers only to non-human animals. The study of non-human animals is known as zoology. Most living animal species are in the Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes—in which many groups of invertebrates are found, such as nematodes, arthropo. Its surface and shores are Sybaris amassed great wealth thanks to its fertile land and busy port.
Its inhabitants became famous among the Greeks for their hedonism, feasts, and excesses, to the extent that "sybarite" and "sybaritic" have become bywords for opulent luxury and outrageous pleasure-seeking. Astropyga radiata, the red urchin, fire urchin, false fire urchin or blue-spotted urchin, is a species of sea urchin in the family Diadematidae.

It is a large species with long spines and is found in the tropical Indo-Pacific region. It was first described in by the German naturalist Nathaniel Gottfried Leske. These bare areas are red with lines of iridescent blue dots while the colour of the rest of the test and spines varies from reddish brown to purple, dark brown or nearly black. The spines are long and hollow; they are of two kinds, the shorter being venomous. The anal sac is prominent, brown with a dark tip. Juveniles have spines with transverse banding and this characterist. The octopus is a soft-bodied, eight-limbed mollusc of the order Octopoda.
Around species are recognised, and the order is grouped within the class Cephalopoda with squids, cuttlefish, and nautiloids. Like other cephalopods, the octopus is bilaterally symmetric with two eyes and a beak, with its mouth at the center point of the eight limbs traditionally called "arms", also mistakenly called "tentacles". The soft body can rapidly alter its shape, enabling octopuses to squeeze through small gaps. They trail their eight appendages behind them as they swim.
The siphon is used both for respiration and for locomotion, by expelling a jet of water. Octopuses have a complex nervous system and excellent sight, and are among the most intelligent and behaviourally diverse of all invertebrates. Octopuses inhabit various regions of the ocean, including coral reefs, pelagic waters, and the seabed; some live in the intertidal zone and others at abyssal depths. Most species grow quickly, mature early and are short-lived. The hierarchy of biological classification's eight major taxonomic ranks.
A genus contains one or more species. Intermediate minor rankings are not shown. In biology, a species listen is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche.
In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. While these definitions may seem adequate, when looked at more closely they represent problematic species concepts. For example, the boundaries between closely related species become unclear with hybridisation, in a species complex of hundreds of similar microspecies, and in a ring species.
Also, among o. The mandarin duck Aix galericulata is a perching duck species native to East Asia. It is closely related to the North American wood duck, the only other member of the genus Aix. Aix is an Ancient Greek word which was used by Aristotle to refer to an unknown diving bird, and galericulata is the Latin for a wig, derived from galerum, a cap or bonnet. The male's breast is purple with two vertical white bars, and the flanks ruddy, and he has two orange "sails" at the back large feathers that stick up like boat sails.
The female is similar to the female wood duck, with a white eye-ring and stripe running back from the eye, but is paler below, has a small white flank stripe, and a pale tip to its bill. Like many other. The Delta begins slightly down-river from Cairo. The delta is sometimes divided into sections, with the Nile dividing into two main distributaries, the Damietta and the Rosetta, flowing into the Mediterranean at port cities with the same name. In the past, the delta h. The history of zoology before Charles Darwin's theory of evolution traces the organized study of the animal kingdom from ancient to modern times.
Although the concept of zoology as a single coherent field arose much later, systematic study of zoology is seen in the works of Aristotle and Galen in the ancient Greco-Roman world. This work was developed in the Middle Ages by Islamic medicine and scholarship, and in turn their work was extended by European scholars such as Albertus Magnus. During the European Renaissance and early modern period, zoological thought was revolutionized in Europe by a renewed interest in empiricism and the discovery of many novel organisms.
Prominent in this movement were the anatomist Vesalius and the physiologist William Harvey, who used experimentation and careful observation, and naturalists such as Carl Linnaeus and Buffon who began to classify the diversity of life and the fossil record, as well as the development and behavior of organisms. Microscopy revealed the previou. Fig wasps are wasps of the superfamily Chalcidoidea which spend their larval stage inside figs.
Most are pollinators but others simply feed off the plant. The non-pollinators belong to several groups within the superfamily Chalcidoidea, while the pollinators are in the family Agaonidae. While pollinating fig wasps are gall-makers, the remaining types either make their own galls or usurp the galls of other fig wasps; reports of them being parasitoids are considered dubious. He believed that the psen was generated spontaneously; he did not recognise that the fig was reproducing sexually and that the psen was assisting in that process.

Owned by the state, the Arsenal was responsible for the bulk of the Venetian republic's naval power during the middle part of the second millennium AD. It was "one of the earliest large-scale industrial enterprises in history". The ferruginous duck, also ferruginous pochard, common white-eye or white-eyed pochard Aythya nyroca is a medium-sized diving duck from Eurasia.
The scientific name is derived from Greek aithuia an unidentified seabird mentioned by authors including Hesychius and Aristotle, and nyrok, the Russian name for a duck. In flight the white belly and underwing patch are visible. The females are duller and browner than the males. The male has a yellow eye and the females have a dark eye. In some areas it will use saline or brackish pools or wetlands. On passage and wintering will also frequent coastal waters, inland seas and large, open lagoons. The term teleonomy has also been proposed.
Before Darwin, organisms were seen as existing because God had designed and created them; their features such as eyes were taken by natural theology to have been made to enable them to carry out their functions, such as seeing. Evolutionary biologists often use similar teleological formulations that invoke purpose, but these imply natural selection rather than actual goals, whether conscious or not.
Dissenting biologists and religious thinkers held that evolution itself was somehow goal-directed orthogenesis , and in vitalist versions, driven by a purposeful life force. Since such views. Organisms are grouped together into taxa singular: taxon and these groups are given a taxonomic rank; groups of a given rank can be aggregated to form a super-group of higher rank, thus creating a taxonomic hierarchy. The principal ranks in modern use are domain, kingdom, phylum division is sometimes used in botany in place of phylum , class, order, family, genus, and species.
The Swedish botanist Carl Linnaeus is regarded as the founder of the current system of taxonomy, as he developed a system known as Linnaean taxonomy for categorizing organisms and binomial nomenclature for naming organisms. With the advent of such fields of study as phylogenetics, cladistics, and systematics, the Linnaean system has progressed to a system of modern biological clas. Oceans average nearly four kilometres in depth and are fringed with coastlines that run for , kilometres. Given that in biology many phyla, families and genera have some species that live in the sea and others that live on land, marine biology classifies species based on the environment rather than on taxonomy.

A large proportion of all life on Earth lives in the ocean. The exact size of this large proportion is unknown, since many ocean species are still to be discovered. The habitats studied in marine biology include everything from the tiny layers of surface water in which organisms and abiotic items may be trapped in surface tension between the ocean and atmosphere, to the depths of the oceanic trenches, sometimes 10, meters or more b.

The Italian protectorate of Albania, also known as Greater Albania, existed as a protectorate of the Kingdom of Italy.
It was practically a union between Italy and Albania, officially led by Italy's King Victor Emmanuel III and its government: Albania was led by Italian governors, after being militarily occupied by Italy, from until During this time, Albania ceased to exist as an independent country and remained as an autonomous part of the Italian Empire led by Italian government officials, who intended to make Albania part of a Greater Italy by assimilating Albanians as Italians and colonizing Albania with Italian settlers from the Italian Peninsula to transform it gradually into an Italian land.
The pygmy mammoth is an example of insular dwarfism, a case of Foster's rule, its unusually small body size an adaptation to the limited resources of its island home. A biological rule or biological law is a generalized law, principle, or rule of thumb formulated to describe patterns observed in living organisms. Biological rules and laws are often developed as succinct, broadly applicable ways to explain complex phenomena or salient observations about the ecology and biogeographical distributions of plant and animal species around the world, though they have been proposed for or extended to all types of organisms.
Many of these regularities of ecology and biogeography are named after the biologists who first described them. In his biology, Aristotle inferred rules governing differences between live-bearing tetrapods in modern terms, terrestrial placental mammals. Among his rules were that. These enzyme-catalyzed reactions allow organisms to grow and reproduce, maintain their structures, and respond to their environments.
The word metabolism can also refer to the sum of all chemical reactions that occur in living organisms, including digestion and the transport of substances into and between different cells, in which case the above described set of reactions within the cells is called intermediary metabolism or intermediate metabolism. Metabolic reactions may be categorized as catabolic - the bre.

It is a form of chemiluminescence. Bioluminescence occurs widely in marine vertebrates and invertebrates, as well as in some fungi, microorganisms including some bioluminescent bacteria and terrestrial invertebrates such as fireflies. In some animals, the light is bacteriogenic, produced by symbiotic organisms such as Vibrio bacteria; in others, it is autogenic, produced by the animals themselves.
In a general sense, the principal chemical reaction in bioluminescence involves some light-emitting molecule and an enzyme, generally called the luciferin and the luciferase, respectively. Because these are generic names, the luciferins and luciferases are often distinguished by including the species or group, i. Currently, the Jewish community of Antwerp consists of around 18, While it is not known precisely where they settled, this is considered to be the establishment of the Jewish community in the region.
The first Jewish presence in Antwerp is attested to by the will of Henry III, the Duke of Brabant and Margrave of Antwerp, who in expressed his wish that the Jews of Brabant should be expelled and destroyed because they were all considered "usurers". A new group of Jewish immigrants started to settle in Antwerp in the early 16th century, when the city became a relat.

He was a pioneer of mathematical biology, travelled on expeditions to the Bering Strait and held the position of Professor of Natural History at University College, Dundee for 32 years, then at St Andrews for 31 years. Thompson is remembered as the author of the book On Growth and Form, which led the way for the scientific explanation of morphogenesis, the process by which patterns and body structures are formed in plants and animals.
