Is the color of a fly important? It is very important to know if the color of the fly is important for fly fishers because the flies are tied on a hook look like an actual fly in nature. The correct fly can yield a great amount of fish while the wrong fly could leave you without a fish all day. So does the color of the fly matter? Fish have been around for over 450 million years, they have learned to adapt over the thousands of years. Living in the aquatic system is not easy there are many dangers both in and outside of the water that can endanger a fish’s existence. Sound travels five times faster in water then in air, fish have adapted to use both their inner ears and lateral lines to avoid a prey. Fish have also developed the sense of smell that is said to be a million times better than humans; they use their sense of smell to smell their prey and identify fish from their species when it comes to reproduction time. Water plays a significant role and a challenge to the fish and fishermen when it comes to vision and color. Water will change the color of an object in the water and in air. For example, a fly will be a different color in the air compared to when it is in the water. Many fish also have the ability to see colors we cannot see such as ultra violet.
Attenuation occurs when light enters the water and changes

They only use their vision right before they attack their prey. Most fish see well in dirty water and low light and are believed to be near sided with the exception of sharks. They also have the ability to detect colors that are typical in their environment. Most fish hunt for their prey by seeing the change in different background colors. The change in contrast depends on time of day, type of bottom, waters transparency, if its cloudy or not and the time of the year. All the different factors can play in influence in how see fish see
Different wavelengths of light determine what colors we see in fish and other organisms. For instance, the changes of season affecting length of daylight triggers many species in the wild to change into their extreme breeding dress. Scientific studies exhibit numerous reports of fish that faded in color after becoming blind, an observation that would have some implications for fish kept in the dark.
Their shapes and patterns are similar with the majority displaying three wide stripes which are placed vertically across their bodies. The reason why these beautiful fish are known as peacock bass is because they all possess a spot on their tail fins that imitates the eye on a peacock’s feathers. The eye is used by both the peacock and the peacock fish, as a defense mechanism against predators. In addition, the eye can be used by the peacock fish as a lure of its own when
All animals under go a process of constant change in their physical appearance and in their behaviour. These changes take place over millions of years and the species that survive, do so because throughout their evolution they have perfected certain strategies that have enabled them to develop more successfully in the environment they inhabit. One such case of this successful development is the great hammerhead shark.
Seahorses have excellent eyesight and their eyes are able to work independently on either side of their head. This
In “Hooked on a Myth”, Victoria Braiyhwaite states that fish feel pain. Even though many think otherwise. I totally agree. In spite of the fact that fish might be seen as dumb , that does not imply that they can't feel pain. I've never been fishing but i can only imagine how much pain they go through and we don't realize because they show empty expressions. In any case, if no one shows their emotions you won't realize what they're going through.
A fish is a creature that preceded the creation of man on this planet. Therefore, Bishop supplies the reader with a subject that is essentially constant and eternal, like life itself. In further examination of this idea the narrator is, in relation to the fish, very young, which helps introduce the theme of deceptive appearances in conjunction with age by building off the notion that youth is ignorant and quick to judge. Bishop's initial description of the fish is meant to further develop this theme by presenting the reader with a fish that is "battered," "venerable," and "homely." Bishop compares the fish to "ancient wallpaper.
They can be almost every color in the world, even the made up ones like Mint and Blurple. Angelfish have a black spot in the center of their foreheads that is called the fake eye, but it's not just black, it is a ring with a shade of royal or dark blue. The Emperor has a yellow tail and its face can be sky or baby blue. This fish wears a black band over its eyes and wears it as if the fish were wearing a Batman mask all day and night.
On average they weigh 4,000-7,000 pounds and grow approximately 16-20 feet long ( Great white sharks 1). < commentary needed>Great Whites are the apex predator of the ocean containing 300 serrated teeth and highly-developed senses to hunt prey. Sharks have a great senses of smell, the Great White can smell a drop of blood thousand of miles away. They’re hearing is very powerful , being able to hear the vibrations of prey distances of about 800 ft away and find the exact location through ‘ear stone’( Great white 3). A shark 's sense of hearing truly shows their uniqueness as an apex predator. In addition to great hearing they’re known to have great sight by being able to see up to 50ft away and transition into seeing in light and dark. Additionally sharks have a lateral line on their back that reaches from the front to the back tail, allowing
One of the most important (and most interesting) conclusions of the biology of vision is that color is not technically generated by physical reality. Color appears to be a mental construct, and therefore, everyone views color differently. The rationale one is often given for the color of particular objects is the following: light consists of all colors. When light strikes an object in absorbs most of the wavelengths of light, but those that it reflects correspond to the color one sees.
• You need to know that fish has senses. They can hear, taste, see, and smell. They have lateral line which helps them to detect movement in water. When they are in danger, they can run away. You will really have to watch your movements because you do not want to go away with empty hands.
Most people think that sharks are large, fast-swimmers, and savage predators. This is true of some species and groups should be interested of the appealing aspects of biology found within it: all sharks have an excellent sense of smell; some can detect electrical discharges; some sharks give birth to one of the
In general, electroreceptive fishes are categorized into non-electric fishes and electric fishes (Crampton & Albert, 2005). On the one hand, non-electric fish do not possess electric organs and use passive electroreception, which is when the fish reacts to external electric stimuli (2005). On the other hand, electric fish are fishes that have specialized electric organs (electrosensory organs) present and use active electroreception, which produce or generate electrical stimuli (2005). The receptors that electric or non-electric fishes use to detect the electrical stimuli are called pit organs that are often open to the surrounding water by way of canals that are filled with an electrically conductive gelatinous substance (2005). There are two types of pit organs: tuberous electroreceptive organ, which are used in active electroreception, and ampullary electroreceptive organ, which is used in passive electroreception.
Freshwater fish and saltwater fish are very similar in a lot of ways, but also have differences between them so you can tell them apart. Marine water (saltwater) equals over 96 percent of the water on Earth and over 70 percent of Earth’s total surface. Freshwater is less than four percent of Earth’s total water and is about one percent of Earth’s surface (Freshwater Fish). Interestingly a few species of fish can live in either freshwater or saltwater, but for the majority, they must live in a specific environment. All species of fish used to live in a saltwater environment until certain geological events (earthquakes, volcanic activity, etc.) occurred, creating conditions that isolated groups of fish. The new habitats, included freshwater, and new food sources caused fish to either adapt, or to die (Lohrey).
Fish are one of Allah’s mighty creations on this world. Fish are just another common type of organism which exists on this Earth. Fish are everywhere; from the aquarium in an office to the Atlantic Ocean and from the book “Fish Tales” to the notorious movie “Finding Nemo.” The term fish usually refers to a cold blooded (exothermic) aquatic vertebrate which lives and swims inside the water.
