Coincident Disruptive Coloration
Coincident disruptive coloration or coincident disruptive patterns are patterns of disruptive coloration in animals that go beyond the usual camouflage function of breaking up the continuity of an animal's shape, to join up parts of the body that are separate. This is seen in extreme form in frogs such as ''Afrixalus fornasini'' where the camouflage pattern extends across the body, head, and all four limbs, making the animal look quite unlike a frog when at rest with the limbs tucked in. A special case is the disruptive eye mask that camouflages the most conspicuous feature of many animals, the eye. Camouflage mechanism Historical description The English zoologist and camouflage expert Hugh Cott explained, while discussing "a little frog known as ''Megalixalus fornasinii''" in the chapter on coincident disruptive coloration in his 1940 book ''Adaptive Coloration in Animals'', that Cott concluded that the effect was concealment "so long as the false configuration is rec ...

Vertebrate
Vertebrates () comprise all animal taxa within the subphylum Vertebrata () ( chordates with backbones), including all mammals, birds, reptiles, amphibians, and fish. Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 69,963 species described. Vertebrates comprise such groups as the following: * jawless fish, which include hagfish and lampreys * jawed vertebrates, which include: ** cartilaginous fish (sharks, rays, and ratfish) ** bony vertebrates, which include: *** ray-fins (the majority of living bony fish) *** lobe-fins, which include: **** coelacanths and lungfish **** tetrapods (limbed vertebrates) Extant vertebrates range in size from the frog species ''Paedophryne amauensis'', at as little as , to the blue whale, at up to . Vertebrates make up less than five percent of all described animal species; the rest are invertebrates, which lack vertebral columns. The vertebrates traditionally include the hagfish, which do no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pastry
Pastry is baked food made with a dough of flour, water and shortening (solid fats, including butter or lard) that may be savoury or sweetened. Sweetened pastries are often described as '' bakers' confectionery''. The word "pastries" suggests many kinds of baked products made from ingredients such as flour, sugar, milk, butter, shortening, baking powder, and eggs. Small tarts and other sweet baked products are called pastries as a synecdoche. Common pastry dishes include pies, tarts, quiches, croissants, and pasties. The French word pâtisserie is also used in English (with or without the accent) for the same foods. Originally, the French word referred to anything, such as a meat pie, made in dough (''paste'', later ''pâte'') and not typically a luxurious or sweet product. This meaning still persisted in the nineteenth century, though by then the term more often referred to the sweet and often ornate confections implied today. Pastry can also refer to the pastry dough, from w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Innes Cuthill
Innes C. Cuthill (born 1960) is a professor of behavioural ecology at the University of Bristol. His main research interest is in camouflage, in particular how it evolves in response to the colour vision of other animals such as predators. Life Innes Cuthill was educated at University College School, London. He read zoology at the University of Cambridge, graduating in 1982 and gained his D.Phil. at the University of Oxford in 1985. He worked at Oxford until 1989 when he became a lecturer at the University of Bristol. He became a professor there in 1998 and was head of the School of Biological Sciences there from 2008 to 2012. He describes himself as "wear ngtwo hats, behavioural ecologist and sensory ecologist", unified by seeking to explain the "design, through natural selection, of animal form and function." He states that his main research interest is in the evolution of camouflage of one kind of animal, such as prey, in response to the colour vision of another kind of animal, ...

Sepia Apama
Giant cuttlefish also known as the Australian giant cuttlefish (scientific name ''Sepia apama''), is the world's largest cuttlefish species, growing to in mantle length and up to in total length (total length meaning the whole length of the body including outstretched tentacles). They can be over in weight. Using cells known as chromatophores, the cuttlefish can put on spectacular displays, changing color in an instant. The giant cuttlefish is native to temperate and subtropical waters of Australia, from Brisbane in Queensland to Shark Bay in Western Australia and Tasmania to the south. It occurs on rocky reefs, seagrass beds, and sand and mud seafloor to a depth of . In 2009 the species was listed at Near Threatened on the IUCN Red List of Threatened Species due to an observed declining trend at that time. Lifecycle and reproduction Giant cuttlefish live 1–2 years. Breeding takes place with the onset of the southern winter. Males abandon their normal cryptic coloring an ...

Signalling Theory
Within evolutionary biology, signalling theory is a body of theoretical work examining communication between individuals, both within species and across species. The central question is when organisms with conflicting interests, such as in sexual selection, should be expected to provide honest signals (no presumption being made of conscious intention) rather than cheating. Mathematical models describe how signalling can contribute to an evolutionarily stable strategy. Signals are given in contexts such as mate selection by females, which subjects the advertising males' signals to selective pressure. Signals thus evolve because they modify the behaviour of the receiver to benefit the signaller. Signals may be honest, conveying information which usefully increases the fitness of the receiver, or dishonest. An individual can cheat by giving a dishonest signal, which might briefly benefit that signaller, at the risk of undermining the signalling system for the whole population. Th ...

Active Camouflage
Active camouflage or adaptive camouflage is camouflage that adapts, often rapidly, to the surroundings of an object such as an animal or military vehicle. In theory, active camouflage could provide perfect concealment from visual detection. Active camouflage is used in several groups of animals, including reptiles on land, and cephalopod molluscs and flatfish in the sea. Animals achieve active camouflage both by color change and (among marine animals such as squid) by counter-illumination, with the use of bioluminescence. Military counter-illumination camouflage was first investigated during the Second World War for marine use. More recent research has aimed to achieve crypsis by using cameras to sense the visible background, and by controlling Peltier panels or coatings that can vary their appearance. In animals Active camouflage is used in several groups of animals including cephalopod molluscs, fish, and reptiles. There are two mechanisms of active camouflage in ani ...

Cephalopod
A cephalopod is any member of the molluscan class Cephalopoda (Greek plural , ; "head-feet") such as a squid, octopus, cuttlefish, or nautilus. These exclusively marine animals are characterized by bilateral body symmetry, a prominent head, and a set of arms or tentacles (muscular hydrostats) modified from the primitive molluscan foot. Fishers sometimes call cephalopods "inkfish", referring to their common ability to squirt ink. The study of cephalopods is a branch of malacology known as teuthology. Cephalopods became dominant during the Ordovician period, represented by primitive nautiloids. The class now contains two, only distantly related, extant subclasses: Coleoidea, which includes octopuses, squid, and cuttlefish; and Nautiloidea, represented by ''Nautilus'' and ''Allonautilus''. In the Coleoidea, the molluscan shell has been internalized or is absent, whereas in the Nautiloidea, the external shell remains. About 800 living species of cephalopods have been ident ...

Oxybelis Aeneus
''Oxybelis aeneus'', commonly known as the Mexican vine snake or brown vine snake, is a species of Colubridae, colubrid snake, which is Endemism, endemic to the Americas. Geographic range and habitat ''O. aeneus'' is found from within the Atascosa, Patagonia, and Pajarito mountains of southern Arizona in the United States, through Mexico, to northern South America and Trinidad and Tobago. Within Arizona, ''O. aeneus'' is exclusively affiliated with Madrean Evergreen Woodland communities and the upper reaches of adjacent semidesert grassland habitat. It is usually encountered in trees or shrubs on open, steep, and grassy slopes, but is also associated with wooded canyons, especially those with abundant vegetation. Description ''O. aeneus'' is an extremely slender snake that reaches up to in total length (including a long tail). Its color may vary from gray to brown with a yellow underside.

Predator
Predation is a biological interaction where one organism, the predator, kills and eats another organism, its prey. It is one of a family of common feeding behaviours that includes parasitism and micropredation (which usually do not kill the host) and parasitoidism (which always does, eventually). It is distinct from scavenging on dead prey, though many predators also scavenge; it overlaps with herbivory, as seed predators and destructive frugivores are predators. Predators may actively search for or pursue prey or wait for it, often concealed. When prey is detected, the predator assesses whether to attack it. This may involve ambush or pursuit predation, sometimes after stalking the prey. If the attack is successful, the predator kills the prey, removes any inedible parts like the shell or spines, and eats it. Predators are adapted and often highly specialized for hunting, with acute senses such as vision, hearing, or smell. Many predatory animals, both vertebrate and i ...

Snake
Snakes are elongated, Limbless vertebrate, limbless, carnivore, carnivorous reptiles of the suborder Serpentes . Like all other Squamata, squamates, snakes are ectothermic, amniote vertebrates covered in overlapping Scale (zoology), scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads (cranial kinesis). To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. Lizards have evolved elongate bodies without limbs or with greatly reduced limbs about twenty-five times independently via convergent evolution, leading to many lineages of legless lizards. These resemble snakes, but several common groups of legless lizards have eyelids and external ears, which snakes lack, altho ...
