The mantis shrimp can perceive both polarized light and multispectral images; they have the most complex eyes in the animal kingdom. Human eyes have color receptors for three colors (red, green, and blue); the mantis shrimp has receptors for sixteen types of color, enabling them to see a spectrum far beyond the capacity of the human brain. Seriously, how cool is the mantis shrimp? What might they be able to see that we cannot? What are we missing? When I read about the mantis shrimp and its awesome powers, I had a flash of inspiration. Bells went off in my head as I connected its fantastical vision to something I was so familiar with: astronomy. What if you could turn the eyes of a mantis shrimp skyward? Astronomy has been an overriding passion
Cephalopods are known to be exceptionally intelligent by invertebrate standards and in some respects even rival “higher” vertebrates. These animals have many highly evolved sensory and processing organs that allow them to gain a greater understanding of their environment and their place within it. Due to their advanced structures, many of which are analogous to vertebrate structures, and abilities they have been widely studied. Their methods of learning have been of prime interest and many experiments have been conducted to determine the different ways in which octopuses can learn. From these experiments four main kinds of learning have been identified in octopuses: associative learning, special learning,
Some spiders have better vision than others. For example, hunting spiders have good eyesight at short distances. Their eyesight enables them to form images of their prey and mate. Web-building spiders (the black widow) have poor eyesight. Their eyes are used for detecting changes in light.
As the pistol shrimp uses its powerful snapping craw as a weapon to hunt, it makes such a noise that it can even alter the sound transmissions of submarines. (BBCWorldwide, 2009) In the video clip “Pistol shrimp sonic weapon” it shows how this snapping shrimp uses its sonic weapon, which is a large claw that snaps to releasing bubbles. (BBCWorldwide, 2009) These bubbles are shot at the shrimp’s prey at such temperature that when their released they can reach the sun’s temperature for a instant. (BBCWorldwide, 2009) Although this pistol shrimp has a astonishing feature, its important to analysis the way this snapping shrimp uses its claw to create a load snap noise through cavitation bubbles and the fundamentals behind its claw regrowth from
In The Rainbow Fish by Marcus Pfister tells how a beautiful, extraordinary, yet, self-centered blue fish learns that being beautiful isn’t the key to happiness. The blue fish came to find this lesson when he lost his friends. Pfister takes a simple ocean setting and explores the consequences of an individual’s arrogance toward their peers, the process of humbling of oneself, and the tremendous reward one feels when they learn to share. The story achieves these morals by the author’s use of detailed imager and also, the influence of minor characters on the antihero in order to reveal to the audience the true thematic message; selfish actions bring true happiness.
Shrimp can be very intelligent animals and have very amazing things such as being clear, this may seem weird but yes, they are clear. Shrimp live in the ocean and come in contact with many different plants animals. The most common plant that the shrimp comes in contact the most with and use for protection is seaweed, coral, and algae. Shrimp use the for protection to hide from the other animals they depend on shrimp for their diet, most of these animals are sharks, whales and sometimes crabs are included. The change of having no eyes helps the shrimp hide from these and keeps the population at a good rate and this has also helped overfishing with not having contact with other animals and causing lots of movement to the other animals and fisherman.
The human eye is adapted for aerial vision, which is why scuba divers-or even you and I in the local swimming pool-must wear goggles or a face mask to re-introduce air in front of our eyes in order to see clearly. Among vertebrates in general, the bird eye is frequently described as the most efficient. Its superior quality, combined with the fact that a large number of birds-cormorants, pelicans, seagulls, even ducks, as well as penguins-get their food from water, obviously
Their sensory systems are adaptive to do the things they need to do in order for them to survive and reproduce. Different animals perceive different kinds of sensation, visions, or hearings. Some species don’t perceive color at all by only seeing black and white. Birds have about four different type of cones in their eyes but humans only have three.
Alnut Kelber, Anna Balkenius, and Eric. J. Warrant studied the night-time vision of a nocturnal hawkmoth, Deilephila elpenor. They wanted to know if the hawkmoths can truly see colors at night, or if they are using other means to find the right kind of flowers to feed from. For example, humans cannot see colors at night and therefore have a harder time differentiating between objects using vision alone. However, a person could find food in a dark room using his or her other senses, such as smell or taste, or could rely on colorless vision to choose food based on its shape. The scientists tested a series of experiments to show that hawkmoths use color-vision at night, as opposed to reverting to their other senses like humans do.
Caterpillar’s revenues that are generated come not just from the United States but from many other countries they do business in . This means that they have to deal with different currencies. “Caterpillar is exposed to currency exchange rate risk because the firm operates in numerous countries and conducts bu siness in multiple currencies” (Downie, 2015) .
The major cause of the theme of betrayal in Manto’s stories is the frenzy caused during the partition. Partition caused communal conflict and mass dislocation. There is violence all around, accompanied by inhumane practices such as riots and rape. Ironically Manto himself was a victim of dislocation and the frenzy of the partition. During the time of the partition he began to drink excessively. He was met with extreme poverty and depression. Manto in his writing has been extremely blunt and has written about the bitter reality of the time. Perhaps this is why his main characters were mostly deprived and lonely people including prostitutes and beggars. Also his description is vivid which in turn reflects his state as well. He penned down most of what he observed around him from a very neutral perspective. In most of Manto’s stories the characters do not completely meet their closure. Death is the ultimate end. This notion is important in the way how loyalty between characters plays its part to meet this final end - death. In ‘The Assignment’ the story ends with Santokh Singh remaining loyal to his ancestors yet betraying Mian Sahib. Manto has written talking of the partition "were the times when philosophy, argumentation or logic had lost their meaning;they were nothing but an exercise in futility"(Manto 103). As mentioned previously madness and betrayal go hand in hand. When people live as if there is no tomorrow, when people have literally nothing to lose there is chaos. This chaos leads to bestiality which is very much evident in stories like ‘Bitter Harvest’. When there is bestiality people lose control, people lose rationality.This lose of rationality leads to irrational decisions which eventually lead to betrayal. This is s...
There are few animals in the world that have as medically significant biology as mosquitoes. Carrying diseases that annually kill thousands, if not millions, of people worldwide, mosquitoes and the way they interact with pathogens are topics of concern for many researchers. As invertebrates, mosquitoes possess various immune responses designed to rid themselves of pathogens. Study of these immune responses has led to a deeper understanding of the ways in which the immune cells of mosquitoes, hemocytes, function and serve the purpose of killing the invasive pathogen. In conjunction with the circulatory system of the mosquito, these immune cells react in various ways upon infection with a pathogen such as a bacterium or virus. The Hillyer Lab
The Animal Kingdom is generally believed to have originated in Archeozoic oceans long before the first fossil record. Every major phylum of animals has at least some marine representatives; some groups, such as cnidarians and echinoderms, are largely or entirely marine lives. From the ancestral marine environment, different groups of animals have invaded fresh water; some have moved onto land. There are over a million described species of animals. About 5% of this number are consists of animal with backbones or simply known as vertebrates. The rest of the 95% consist the greater part of the Animal Kingdom, which are the invertebrates. Backbone is the single characteristic which separates the entire animal kingdom into two groups. However, the most successful animal among all the animal exist are the arthropods which consist of 85% of the animals. Invertebrates do not hold a single positive characteristic in common. Some invertebrates have common phylogenetic origins and others are only remotely related.
Have you ever wondered why the sky is blue. Often times I find myself looking up on a clear day, pondering over that question? Why isn’t it green, or red or pink for even that matter. Every day, the human eye blinks more than 23,00 times. The human eye is a complicated organ that performs one of the most important tasks for our body. There are many questions about the eye however. What function do they perform? What happens if we don’t take care of them? How exactly do they work together to help us form images? Exactly how far can they human eye see?
Ant like insects have been inhabiting this world for over 130 million years, evolving into the insects that we recognize today from their wasp-like ancestors. Ants are one of the planet’s most successful insect species at adaptability and have even been referred to as super-organisms. Their adaptive success is due to their hive-mind like structure. This hive-mind like structure allows ants to not only defend themselves effectively from predators but it also allows them to exploit resources and modify their habitats efficiently. Ants inhabit almost every land mass on the planet with an estimated 12,500 discovered species. (Dvorsky 2012)
Everyone must have asked these questions once in their life, why are ants so important or interesting to the world and life? Well, ants help in a lot of ways; they scatter seeds from place to place allowing more plants to grow all over the land, they pollinate and protect our plants and flowers and they dig galleries and tunnels that increase the nutrients in our soil. Ants have mutualistic relationship with several organisms likes other animals and plants. Ants can also be used as a pesticide for crops, because they keep unwanted harmful insects off the corps and the corps do not have to be sprayed with any deadly chemicals; which makes using ants as a pesticide organic and safer for the environment. Allow me to get more into detail; here are some more interesting facts and jobs that ants do to help us.
