That suggests rural spiders are indeed photophobic while urban spiders, though not actually attracted to the light, have ceased to be afraid of it—not so much Steatoda triangulosa, then, as Steatoda luminosa.

In biology, photophobia (adjective: photophobic) is negative response to light. Photophobia is a behavior demonstrated by insects or other animals which seek to stay out of the light. In botany, the term photophobia/photophobic describes shade-loving plants that thrive in low light conditions. Photophobia (or photophobic response) may also refer to a negative phototaxis or phototropism response.

Researchers have additionally found that blocking serotonin releases clamping. Another experiment found that serotonin also reduces the photophobic behavior in Gammarus lacustris. Thus, it is thought that the thorny-headed worm physiologically changes the behavior of the Gammarus lacustris in order to enter its final host, the bird.

The embryos are brooded there before being released as planula larvae into the water column. The larvae are photophobic and soon settle on the seabed. Once there, they develop into polyps and start secreting gorgonin to form the skeleton. Further growth of the colony is by budding of new polyps.

As shown in the third film, the Gill- man has a dormant set of lungs, should its gills be irreparably damaged. As shown in the first film, it is vulnerable to rotenone. The Gill-man is slightly photophobic, due to its murky water habitat. 35% of the Gill-man's blood is composed of white corpuscles, lacking a nucleus.

G. lacustris typically shows photophobic behaviour, but when parasitized this can be altered to photophilic behaviour when infected by Pomphorhynchus laevis. Which is a host manipulation parasite, like many others. Parasites can affect the diel migration of G. lacustris, making it more visible and susceptible to predation most likely aiding parasite transmission. More mature parasites have greater effects on hosts.

They feed off the nutrients in the bloodstream of its host, destroying the internal organs in the process. It then burrows into the brain of the carrier and manipulates it for the benefit of the Parasite. The Parasite causes the host to become aggressive and photophobic. The bite of the host serves to spread the Parasite's eggs, which are released into the saliva, to a new host.

Blepharisma are markedly photophobic, and when light levels are increased will seek out darkened areas. The ability to detect light is accomplished with photosensitive pigment granules located just under the plasma membrane of the cell. The pigment in these granules is blepharismin, the same substance that gives Blepharisma their characteristic pinkish color. Blepharisma are usually pink when collected in nature, but when grown in darkness with abundant food they turn red.

Parhippolyte uvae occurs in anchialine pools and marine caves. In Hawaii it occurs in lava pipes and caves whereas on other islands it is found in more open areas. P. uveae varies in its behaviour from location to location. For example, the population of P.uveae in the lagoon at Kakaban Island appears to be photophobic and was only recorded being active at night, while the population from Tinguiban Islet in the Philippines were described as being "sun-lovers".

The syndrome is frequently noticed first in children around six months of age by their photophobic activity or their nystagmus. The nystagmus becomes less noticeable with age but the other symptoms of the syndrome become more relevant as school age approaches. Visual acuity and stability of the eye motions generally improve during the first six to seven years of life – but remain near 20/200. The congenital forms of the condition are considered stationary and do not worsen with age.

Acutely, early symptoms include a painful, photophobic, red watery eye. This is due to active corneal inflammation resulting in vascular invasion and stromal necrosis which can be diffuse or localized. This causes the pinkish discoloration of what was a clear transparent normal corneal tissue (called Salmon patch of Hutchinson). Such vascularization is likely to result in blurring of vision secondary to corneal stromal scarring, the presence of ghost vessels, and thinning of the cornea, especially if it involves the visual axis.

Desperate, he Carlo, being widowed, and his family set up the funeral parlor to cover up their true nature and to earn for a living. This explained their photophobic features and the fact of dismissing Dianne every evening before sundown. Dianne confronted the group, demanding they surrender Dennis. Throwing formaldehyde and setting the parlor aflame as a diversion, Dianne and her brother narrowly escaped Sarah's and Carlo's assaults, while Ryan, the only aswang member of the family that refuses to harm anyone, begged to go with her.

Two species live in caves, a habitat to which their ability to squeeze themselves into the smallest cracks makes them exceptionally well-adapted and in which constant living conditions are guaranteed. Since the essential requirements for cave life were probably already present prior to the settlement of these habitats, this may be described as exaptation. Agriculture has apparently made available new habitats for velvet worms; in any case, they are found in man- made cocoa and banana plantations in South America and the Caribbean. Velvet worms are photophobic: They are repelled by bright light sources.

This microbe is photophobic, and will generate a biofilm matrix, or form clumps with other microbes, to avoid light. The species Nitrosomonas europaea has been identified as being able to degrade a variety of halogenated compounds including trichloroethylene, benzene, and vinyl chloride. Some Nitrosomonas species possess the enzyme urease, which catalyzes the conversion of the urea into ammonia and carbon dioxide. N. europaea, as well as populations of soil-dwelling ammonia-oxidizing bacteria (AOB), have been shown to assimilate the carbon dioxide released by the reaction to make biomass via the Calvin cycle, and harvest energy by oxidizing ammonia (the other product of urease) to nitrite.

Channelrhodopsin-1 (ChR1) or channelopsin-1 (Chop1; Cop3; CSOA) of C. reinhardtii is closely related to the archaeal sensory rhodopsins. It has 712 aas with a signal peptide, followed by a short amphipathic region, and then a hydrophobic N-terminal domain with seven probable TMSs (residues 76-309) followed by a long hydrophilic C-terminal domain of about 400 residues. Part of the C-terminal hydrophilic domain is homologous to intersectin (EH and SH3 domain protein 1A) of animals (AAD30271). Chop1 serves as a light-gated proton channel and mediates phototaxis and photophobic responses in green algae. Based on this phenotype, Chop1 could be assigned to TC category #1.

Based on action spectroscopy and simultaneous recordings of photocurrents and flagellar beating, it was determined that the photoreceptor currents and subsequent flagellar movements are mediated by rhodopsin and control phototaxis and photophobic responses. The extremely fast rise of the photoreceptor current after a brief light flash led to the conclusion that the rhodopsin and the channel are intimately linked in a protein complex, or even within one single protein. However, biochemical purification of the rhodopsin- photoreceptor(s) was unsuccessful for many years. The nucleotide sequences of the rhodopsins now called channelrhodopsins ChR1 and ChR2 were finally uncovered in a large-scale EST sequencing project in C. reinhardtii.

They have a natural range extending from Scandinavia to North Africa and from Europe to Korea; there are also transplanted populations as far apart as Japan and Madagascar. The adult spiders are photophobic and live in places free from light, frequently in caves and tunnels, though they can sometimes be seen outside of caves and mines as they will emerge around dusk to hunt, often using a single silk lasso line and swinging down upon their prey. They are often found in areas that are frequented by bats. The spiders are most often observed in railway tunnels and mines since these are more likely to be visited by humans.

With Goma's aid, Zajio obtains discarded pieces of Daguva's buckle and refines them to create a means for a Grongi to have the same abilities as Daguva and Kuuga, so those in the Gegeru can defend themselves against Daguva. In the end, Zajio is eventually killed by Daguva just as he finished his final work. Like Baruba, Zajio's true form was never revealed. ; : A photophobic vampire bat-like Grongi labeled and , Goma initially murdered a preacher named Father Jose and disguised himself to use a church as a base of operations before Ichijo uncovered the truth and the Grongi is ultimately forced to retreated.

Schematic representation of a Euglena cell with red eyespot (9) Schematic representation of a Chlamydomonas cell with chloroplast eyespot (4) The eyespot apparatus (or stigma) is a photoreceptive organelle found in the flagellate or (motile) cells of green algae and other unicellular photosynthetic organisms such as euglenids. It allows the cells to sense light direction and intensity and respond to it, prompting the organism to either swim towards the light (positive phototaxis), or away from it (negative phototaxis). A related response ("photoshock" or photophobic response) occurs when cells are briefly exposed to high light intensity, causing the cell to stop, briefly swim backwards, then change swimming direction. Eyespot-mediated light perception helps the cells in finding an environment with optimal light conditions for photosynthesis.

Purple bacteriorhodopsin in Halobacteria at Cargill's salt evaporation ponds in San Francisco Bay, located at Newark, California Microbial rhodopsins, also known as bacterial rhodopsins are retinal-binding proteins that provide light- dependent ion transport and sensory functions in halophilic and other bacteria. They are integral membrane proteins with seven transmembrane helices, the last of which contains the attachment point for retinal (a conserved lysine). This protein family includes light-driven proton pumps, ion pumps and ion channels, as well as light sensors. For example, the proteins from halobacteria include bacteriorhodopsin and archaerhodopsin, which are light-driven proton pumps; halorhodopsin, a light-driven chloride pump; and sensory rhodopsin, which mediates both photoattractant (in the red) and photophobic (in the ultra-violet) responses.

Dianne (Carla Abellana) works as a part- time tutor for the Gonzales', the owners of a local funeral parlor, which is said to be the lair of rumored werewolves. On her first day, she met the patriarch Carlo (Sid Lucero), the children - Ryan (Nash Aguas) and Sarah (Anna Vicente) -, the family's butlers Aludia (Odette Khan) and Simeon (Jess Evardone), and the secretary Anna (Gaby dela Merced). After a series of successful tutorial sessions, it gradually became clear to Dianne the nature of the family: being photophobic, having a desire for human entrails, and, worst of all, the unusual activity in and out of the parlor. Dennis (Mart Escudero), Dianne's brother, dismissed his sister's stories; meanwhile, Ryan was accused of divulging the truth to Dianne, creating a tension between Carlo and the tutor.

Here, Bruegel gives each man a different ocular affliction, all painted with a realism that allowed identification of their conditions by later experts, though there is still some diagnostic disagreement. French anatomical pathologist Jean-Martin Charcot and anatomical artist Paul Richer published an early account, ' ("The deformed and sick in art", 1889), and French pathologist Tony-Michel Torrillhon followed with more research on Bruegel's figures in 1957. The first man's eyes are not visible; the second has had his eyes removed, along with the eyelids: the third suffers from corneal leukoma; the fourth atrophy of the globe; the fifth is either blind with no light perception, or photophobic; and the sixth has pemphigus or bullous pemphigoid. Charcot and Richer noted Bruegel's accuracy in portraying the blind men facing not forward but with their faces raised in the air, as they would have had to rely on their senses of smell and hearing.

The Pimelodella kronei is an endemic troglobitic species, so exclusively subterranean, found in cave streams along the Betari River basin, a tributary of the upper Ribeira de Iguape River. The species is adapted to food scarcity typical of the underground and seems to be in the midst of a process of loss of cryptobiotic habits - the blind catfish are little or no photophobic and spend a lot of time actively exploring the whole environment, not only the bottom but also the water column and the surface, and as other troglobitic fish, is oriented toward any stimulus, apparently interpreting them as a sign of food. It is highly susceptible to environmental fluctuations, depending on the relative stability of the underground, and with low rates of reproduction and growth (it grows less than 1 mm a month, but has high longevity of 15 to 20 years) and therefore it presents low capacity to replace the population losses due to natural or anthropogenic causes. The increase in activity and the loss of these defense mechanisms makes it a very vulnerable species.
