Star Jelly
Star jelly (also called astromyxin, astral jelly) is a gelatinous substance sometimes found on grass or even on branches of trees. According to folklore, it is deposited on the Earth during meteor showers. It is described as a translucent or grayish-white gelatin that tends to evaporate shortly after having "fallen". Explanations have ranged from it being the remains of frogs, toads, or worms, to the byproducts of cyanobacteria. Reports of the substance date back to the 14th century and have continued to the present. History There have been reports of 'star-jelly' for centuries. John of Gaddesden (1280–1361) mentions ''stella terrae'' (Latin for 'star of the earth' or 'earth-star') in his medical writings, describing it as "a certain mucilaginous substance lying upon the earth" and suggesting that it might be used to treat abscesses. There is another reference to ''stella terrae'', as a component in a medical recipe, on folio 49 of the same work. A fourteenth-century Latin medic ...

A Moss (Grimmia Pulvinata), With "mystery Jelly" - Geograph
A, or a, is the first letter and the first vowel of the Latin alphabet, used in the modern English alphabet, the alphabets of other western European languages and others worldwide. Its name in English is ''a'' (pronounced ), plural ''aes''. It is similar in shape to the Ancient Greek letter alpha, from which it derives. The uppercase version consists of the two slanting sides of a triangle, crossed in the middle by a horizontal bar. The lowercase version can be written in two forms: the double-storey a and single-storey ɑ. The latter is commonly used in handwriting and fonts based on it, especially fonts intended to be read by children, and is also found in italic type. In English grammar, " a", and its variant " an", are indefinite articles. History The earliest certain ancestor of "A" is aleph (also written 'aleph), the first letter of the Phoenician alphabet, which consisted entirely of consonants (for that reason, it is also called an abjad to distinguish it fro ...

Enteridium Lycoperdon
''Enteridium lycoperdon'', the false puffball, is one of the more obvious species of slime mould or Myxogastria, typically seen in its reproductive phase as a white 'swelling' on standing dead trees in the spring, or on large pieces of fallen wood. Alder (''Alnus glutinosa'') is a common host. Taxonomy It was first described in 1791 by Jean Baptiste François Pierre Bulliard as ''Reticularia lycoperdon,'' but was assigned to the genus, '' Enteridium'', by Marie L. Farr in 1976. The name ''Reticularia lycoperdon'' is accepted by the taxonomic databases: Ausfungi Index Fungorum, and IRMNG. Habitats and distribution ''E. lycoperdon'' grows typically on dead alder branches, logs, and stumps in wet places beside rivers, streams and wetlands; it is also found growing on dead elm, beech, poplar, hawthorn, elder, hornbeam, damson, hazel, and pine trees often after late frosts in spring and in the autumn. It is recorded throughout Scotland, England, Wales, Ireland, Europe, and in Me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vomiting
Vomiting (also known as emesis and throwing up) is the involuntary, forceful expulsion of the contents of one's stomach through the mouth and sometimes the Human nose, nose. Vomiting can be the result of ailments like Food-poisoning, food poisoning, gastroenteritis, pregnancy, motion sickness, or hangover; or it can be an after effect of diseases such as brain tumors, elevated intracranial pressure, or overexposure to ionizing radiation. The feeling that one is about to vomit is called nausea; it often precedes, but does not always lead to vomiting. Impairment due to Alcoholic drink, alcohol or anesthesia can cause inhalation of vomit, leading to suffocation. In severe cases, where dehydration develops, intravenous fluid may be required. Antiemetics are sometimes necessary to suppress nausea and vomiting. Self-induced vomiting can be a component of an eating disorder such as bulimia nervosa, bulimia, and is itself now classified as an eating disorder on its own, purging di ...

Thomas Pennant
Thomas Pennant (14 June Old Style, OS 172616 December 1798) was a Welsh natural history, naturalist, traveller, writer and antiquarian. He was born and lived his whole life at his family estate, Downing Hall near Whitford, Flintshire, in Wales. As a naturalist he had a great curiosity, observing the geography, geology, plants, animals, birds, reptiles, amphibians and fish around him and recording what he saw and heard about. He wrote acclaimed books including ''British Zoology'', the ''History of Quadrupeds'', ''Arctic Zoology'' and ''Indian Zoology'' although he never travelled further afield than continental Europe. He knew and maintained correspondence with many of the scientific figures of his day. His books influenced the writings of Samuel Johnson. As an antiquarian, he amassed a considerable collection of art and other works, largely selected for their scientific interest. Many of these works are now housed at the National Library of Wales. As a traveller he visited Sco ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Amphibian
Amphibians are tetrapod, four-limbed and ectothermic vertebrates of the Class (biology), class Amphibia. All living amphibians belong to the group Lissamphibia. They inhabit a wide variety of habitats, with most species living within terrestrial animal, terrestrial, fossorial, arboreal or freshwater aquatic ecosystems. Thus amphibians typically start out as larvae living in water, but some species have developed behavioural adaptations to bypass this. The young generally undergo metamorphosis from larva with gills to an adult air-breathing form with lungs. Amphibians use their skin as a secondary respiratory surface and some small terrestrial salamanders and frogs lack lungs and rely entirely on their skin. They are superficially similar to reptiles like lizards but, along with mammals and birds, reptiles are amniotes and do not require water bodies in which to breed. With their complex reproductive needs and permeable skins, amphibians are often ecological indicators; in re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Frog
A frog is any member of a diverse and largely Carnivore, carnivorous group of short-bodied, tailless amphibians composing the order (biology), order Anura (ανοὐρά, literally ''without tail'' in Ancient Greek). The oldest fossil "proto-frog" ''Triadobatrachus'' is known from the Early Triassic of Madagascar, but molecular clock, molecular clock dating suggests their split from other amphibians may extend further back to the Permian, 265 Myr, million years ago. Frogs are widely distributed, ranging from the tropics to subarctic regions, but the greatest concentration of species diversity is in tropical rainforest. Frogs account for around 88% of extant amphibian species. They are also one of the five most diverse vertebrate orders. Warty frog species tend to be called toads, but the distinction between frogs and toads is informal, not from Taxonomy (biology), taxonomy or evolutionary history. An adult frog has a stout body, protruding eyes, anteriorly-attached tongue, limb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myxarium Nucleatum
''Myxarium nucleatum'' (common names crystal brain or granular jelly roll) is a jelly fungus in the family Hyaloriaceae. The sporocarps (fruit bodies) are watery white and gelatinous with small, white, mineral inclusions. It is a common, wood-rotting species in Europe and North America, typically growing on dead attached or fallen branches of broadleaf trees. Taxonomy History The species was originally described by Karl Friedrich Wilhelm Wallroth in 1833, who found it growing on hawthorn in Germany. He placed it in his new genus ''Myxarium'' based on its visible white inclusions which he interpreted as spores. Wallroth noted its similarity to ''Naematelia nucleata'', but nonetheless described ''Myxarium nucleatum'' as a new species, using the same epithet. Lewis David von Schweinitz had previously described ''Tremella nucleata'' from the United States, a species that was later transferred to the genus ''Exidia'' by Burt. Many subsequent publications, summarized by Donk (196 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Yellow Slime Mold
Yellow is the color between green and orange on the spectrum of light. It is evoked by light with a dominant wavelength of roughly 575585 nm. It is a primary color in subtractive color systems, used in painting or color printing. In the RGB color model, used to create colors on television and computer screens, yellow is a secondary color made by combining red and green at equal intensity. Carotenoids give the characteristic yellow color to autumn leaves, corn, canaries, daffodils, and lemons, as well as egg yolks, buttercups, and bananas. They absorb light energy and protect plants from photo damage in some cases. Sunlight has a slight yellowish hue when the Sun is near the horizon, due to atmospheric scattering of shorter wavelengths (green, blue, and violet). Because it was widely available, yellow ochre pigment was one of the first colors used in art; the Lascaux cave in France has a painting of a yellow horse 17,000 years old. Ochre and orpiment pigments were ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oviducts Of Amphibians Regurgitated By Predators - Lindsey
The oviduct in mammals, is the passageway from an ovary. In human females this is more usually known as the Fallopian tube or uterine tube. The eggs travel along the oviduct. These eggs will either be fertilized by spermatozoa to become a zygote, or will degenerate in the body. Normally, these are paired structures, but in birds and some cartilaginous fishes, one or the other side fails to develop (together with the corresponding ovary), and only one functional oviduct can be found. Except in teleosts, the oviduct is not directly in contact with the ovary. Instead, the most anterior portion ends in a funnel-shaped structure called the infundibulum, which collects eggs as they are released by the ovary into the body cavity. The only female vertebrates to lack oviducts are the jawless fishes. In these species, the single fused ovary releases eggs directly into the body cavity. The fish eventually extrudes the eggs through a small genital pore towards the rear of the body. Fish ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
