How Does Ultraviolet Reflection Affect Color Of Chameleons?

Sophomore Iman Hearing swings her flags gracefully over her shoulder and takes her place in line. As one of six, she marches down to the football field in front of the band, chin lifted and smiling big.

The purpose of this experiment was to observe the light that the Tomopteris emits. They collected Tomopteris from Monterey Bay off the coast of California. They then stimulated the Tomopteris to produce light so that they could observe the light that it produced. The researchers took photos and measured the amount of light that was emitted per Tomopteris. One interesting discovery was a Tomopteris that emits a blue light which is rare since most Tomopteris emit a yellow-orange light. The researchers tried to create explanations as to why this Tomopteris emits blue light. They think that “different protein complements may be responsible for the light in different species”. However, this isn’t their only explanation for this rare blue emitting Tomopteris. The other explanation is that “this could potentially reflect different ecological roles of the two light colors”. Researchers concluded that with further testing the blue-light emitting Tomopteris may be considered a species of their own.

Furthermore, color vision is not only beneficial in the survival of animals in the wild, but also the quality of life of animals in captivity. If an animal’s color vision is able to be determined, then enrichment, diet, and exhibit design can all be modified in a manner that provides the greatest mentally stimulating environment for the perception of that one individual. Ultimately, color vision is an

eyes). They can also change the size of their melanophores to adjust colors slightly, giving them an

When I am asked to think of a situation that was intellectually challenging, my mind shifts directly to my experience in the color guard activity. While the activity is seen as simply a physical sport, there is a mental aspect that is adamant when performing. As a member of the color guard in a marching band, you are required to learn points on the field in which to stand at exact moments in the music, you have to learn to apply corrections, and you also have to fight through the frustration.

The xanthommatin that was found in the brown eyed fly was much more than what was in the wild type, this is because the pteridine pathway that creates all the other pigments is blocked so only the brown pigment is produced. In the rosy eyed fly it was found that the pigments isosepiapterin, sepiapterin, drosopterins, and xanthommatin are the same as in the wild type; the pigments biopterin and isoxanthopterin are more than in the wild type; the 2-amino-4-hydroxypteridine is much more than in the wild type; and the pigment xanthopterin is less than in the wild type. The rosy pigment is made when the enzyme xanthine dehydrogenase is blocked, this causes more to go to the other pigments making the eye appear

Have you ever wondered why the fourteen inch reptile, know as the chameleon can camouflage? If so, I'm here to tell you the Legend of Giroud. To begin, the chameleons are the original conquerors of the North America. They lived in peace in a calm environment, but then, things twisted in another direction. Their prey started to adapt to the chameleons strategies, and left the chameleons in a sticky situation. So the chameleons could no longer catch their prey to survive. Weakened by the food shortage, the chameleons became ill, weak, and started to die off. It started to decrease their population. A brave chameleon decided to help his fellow chameleons, to persevere this challenge. A chameleon in the name of Giroud stepped up to the plate. Let's jump in into Giroud's brave and heroic action,

Organisms possess several types of color vision depending on what wavelengths they are sensitive to. Humans are trichromatic, because their vision is formed by long, middle and short wavelength sensitive cones (Carroll, et.al, 2009). Depending on the environment, primates will have different variations of color vision. (Melin, et.al, 2017). Routine trichromacy and polymorphic trichromacy both track different food sources. Routine trichromacy is helpful for tracking down reddish-yellow fruit and seasonal leaves while polymorphic trichromacy is helpful for tracking down ripe fruits and insects (Melin, et.al, 2017).

The males then with orange spots were selected by females, survived, and were able to produce more orange colored offspring in the process of natural selection. Furthermore, when tested in tea-stained water, guppies pecked at red the most, but while in clear water, the fish pecked more at green and yellow. Scientists also notices that green algae (a food source for guppies) only grows in clear water, therefore it is concluded that guppies pecked at the green because it was the color of their food. From all of this data, scientists are able to infer that guppies have a preference for colors that are the same color as their food source. In contrast, not all male guppies have large orange spots due to predator attraction in their environments.

The researchers focused their study on determining whether cuttlefish adjust their body pattern intensity with reference to artificial and natural substrate intensity under different light conditions of bright light, moderate light, low light, and extremely low light. For each set of experiments, 10 adult Sepia officinalis were confined with an artificial or natural substrate placed the floor and walls of a seawater-filled tank and was left to get accustomed to low light for 20 minutes. After those 20 minutes, a photo was taken using a flash, digital camera. The cuttlefish is then left to adapt in a set light condition with the same substrate for another 20 minutes. Following the 20 minutes, the light is turned off and a flash photo was

The scales on a butterfly’s wings are actually modified hairs arranged in rows. The scales deflect light energy, transmitting numerous bright colors to

The color variation of Venezuelan Guppies results from a difference between traits that are beneficial for survival and those that are beneficial for reproduction. While females are more attracted to bright males, predators limit the population of bright males from the top down. Therefore, the population of Venezuelan Guppies differ in color due to the presence, or lack of, predators.

The process of color change in chameleons is simply fascinating. What happens is that chameleons have a top layer of the skin that is transparent, and underneath it there are layers of skin, which contain chromatophores (these are specialized cells that contain pigment). Beneath the transparent layer, there is a layer with xanthophores (contains yellow pigments) and erythrophores (contains red pigments). Under this layer is layer with iridophores (contain blue pigments). At the bottom are melanophores (contain melanin.

The green sea urchin, Strongylocentrotus droebrachiensis, exhibits covering behaviour, a neuromuscular behaviour enlisting their tube feet to lift objects from their environment onto their aboral surface; hypothesized to be a means of protection from UV radiation, wave surge and possibly predation. Three light treatments, were selected to evaluate the behavioural response of the sea urchins to different light intensities: (1) full light, (2) partial light (screened), (3) total darkness (control); this resulted in a positive correlation between covering behaviour and light intensity.

Chamaeleonidae is the scientific name given to them and Chameleon is their common (Vitt, 2014, Para. 1). Most researchers suggest that chameleons originated from a small country beside Africa called Madagascar. For this reason that deep forest of Madagascar is where most of the chameleon species are found. Additionally, forests on the main land of Africa, southern Spain, southern Asia and the Middle East also have different other species of Chameleon (Means, 2013, 372). They are later found in some other countries of the world. Chameleons have very interesting Characteristics and some are so complicated. What if an animal can change its own skin color to
