Fish Informative Speech

Some plants and animals have to adapt to the amount of oxygen and visibility underwater. For example, plants have adapted to the amount of sunlight they receive in certain environments, and cattails and water lilies have adapted to be able to survive humid climates. For animals, certain fish like trout have adapted to clear and cool water with a large amount of oxygen. On the other hand, other types of fish, like catfish, are able to survive in an area with a low oxygen level and gloomy visibility. Since otters live on the land surrounding the water, they have adapted to be able to swim to catch their food. Frogs and alligators have adapted to their environment by being able to live on the land after coming from underwater as an egg. Lastly, beavers have adapted to use their teeth to create the dams they live

The fork in the tail shows that the fish is not a very fast swimmer. The lateral line helps the fish detect predators or prey. The pelvic fins do the job of the dorsal fins to help keep its balance. It uses it's mouth to crush its prey. The pectoral fin helps steer the fish in the direction it wants to go. It has very well developed eyes so it can see its prey and predators very well. The anal fin or fins are used the same way as the pectoral fins and help move the fish it the direction it want to go. The gill cover protects the

This experiment was designed to identify the effect of cold-water temperatures on the respiration rate of goldfish. The respiration rates helped to identify the goldfish as being ectotherms or endotherms. Organisms exchange gases with their environment through a process called respiration or breathing. Aerobic respiration, also known as aerobic metabolism, occurs when oxygen is taken into the body and sent to all its cells; the oxygen is then used to break down food for energy (White and Campo 2008). Respiration can be experienced through several structures such as the lungs, tracheae, gills, and integument in order to obtain

What was the first image that popped into your head when you read the word “Parrotfish”? Did you imagine a rainbow colored fish with wings? Although they do not have wings, Parrotfish are some of the most colorful fish in the world. In fact, when scientists first started studying the Parrotfish in they thought there where over 350 different kinds! Today we know there are only 83 species of Parrotfish (National Audubon

The circulatory system brings in the oxygen that then the lungs take in and transport it around the body and then brings the carbon dioxide back for the lungs to push out(exhale) The lungs bring oxygen into the blood stream which goes to feed the heart and the rest of your body. The respiratory system brings in oxygen, which then the circulatory

The blood is pumped by the heart through the afferent bronchial arteries to capillaries in the gills, where the blood is oxygenated). The blood

The operculum is a late that forms a flap that covers the gills in bony fish. Since it did not have an operculum, the fish most likely moved water or air through respiratory organs by the mouth either pumping or changing shape. In other words, it is possible that Tiktaalik was capable of breathing through its mouth.Thus, Tiktaalik did not solely rely on gills for breathing.

The crayfish has gills but you can not see them under its hard shell body. Hunting mostly at night, the crayfish is an omnivore. The crayfish is large enough to bee seen with an unaided eye. Being an invertebrate the crayfish does not have a backbone.

The Stereolepis gigas, or Giant sea bass, is a fish native to California. They are very large creatures, their typical weight being 562 pounds, and their typical length being 8 feet. Aside from their size, they have big, robust heads with large mouths to help capture their prey. They have long dorsal spines that fit into grooves in their back to help them swim. Their color can vary from reddish brown, to grey, and to dark brown. Most of the time, they have dark colored spots. They have a surprisingly long lifespan, on average, they live to be 75 years or older.

When most people hear the words “ocean life,” they think of FISH. There's more to the ocean than a few fish. The ocean is mysterious and we don't know all of the secrets that live in it. We're here to tell you some interesting things about the ocean. We might not answer the mysteries that live in the ocean, but we will inform you more about the ocean and its creatures.

Their bodies are also shaped somewhat like a torpedo to give them a more streamlined affect in the in water. Yet, some types of sharks, the ocean dwellers have a flat body similar to that of skates and rays. Sharks can travel with great bursts of speed especially when attacking their prey or when excited. The fastest-swimming sharks have a moon-shaped tail that provides extra power and durability for swimming.

There are many different types of fish, but there are four classes: jawless fish, cartilaginous fish, ray-finned fish, and lobe-finned fish. Jawless fish have no jaw but have teeth like the lamprey. Some cartilaginous fish lose their teeth but eventually grow them back like manta rays and sharks. Finally, lobe-finned fish, which are uncommon and rare, are named after their large lobe-like fins. These fish live deep in the ocean and includes the lungfish and, the thought to be extinct, coelacanths.

Insects that live in water also exchange gases with the environment through the trachea. Air can be carried with the insect or it can diffuse into the tracheal system from the water. An example of this are diving beetles. Diving beetles carry a bubble of air under the elytra (wing covers) or trap the bubble of air against their body by specialised hairs. The bubbles one or more spiracle so that the insect can breathe air from the bubble when submerged in water. The air bubble only provides the diving beetle with a short- term supply of oxygen, therefore the bubble is also able to collect some of the oxygen molecules dissolved in the surrounding water. In effect, the bubble acts as a physical gill as it replenishes its supply of oxygen through

Fish exchange gases between the blood and the environment using gills. Gills are thin filamentous, vascular structures located just behind the head. Fish obtain the oxygen they need from the water by means of gills. Gills are membranous structures supported by cartilaginous or bony struts. Gill surfaces are very large due to numerous folds, but the gill filaments are very thin and respiratory gases are exchanged between the blood and the water by diffusion the folds are kept supported and moist by the water that is continually pumped through the mouth and over the gills. Fish Facilitate gas exchange by ventilating the gill surfaces, either by using the gill cover (operculum) as a pump, drawing water past the gill filaments (e.g. bony

The Corydoras is part of the Anabantoidei suborder. This means that although they do have gills, they require both atmospheric and dissolved oxygen in order to survive. Anabantoids or labyrinth fishes have a lung-like organ that allows them to consume airborne oxygen. The Corydoras catfish will frequently rise to the surface of the water to gulp in needed air.
