Mayfly Gills Adaptation

359 Words2 Pages

Adaption 1
Tracheae: an insects tracheae is a complex network of tubes that delivers oxygen-containing air to every cell of the body
Cuticle: in particular an outer layer of living tissue
Mayfly nymph adaptation
An adaptation that mayfly nymphs need most to survive in the water is having gills. On a mayfly nymph there are four to nine pairs of gills that are located on each side of their abdomen. These gills are leaf-like in shape and constantly keep moving back and forward. This beating motion increases the amount of water that goes through the nymphs gills. The gills create currents of water that bring in a fresh oxygen supply. It is important for mayfly nymphs to have these types of gills because in water there is less than one percent of oxygen and the oxygen that there is barely moves. This means if a mayfly nymph stays still in the same place in the water without their gills, not much oxygen will get to it and slowly it will die. Instead of moving itself through the water to get oxygen mayfly nymphs (gills specifically) moves water through itself. …show more content…

This even 's out the amount of water that runs through their body in different habitats.
A mayfly nymph has what you call tracheae gills, which are gills that attach to your tracheae. After air diffuses through the gills, the oxygen moves into the tracheae. From here the tracheae transports it into smaller branches and these branches lead to every part of the body. The gills, being covered by a thin layer of cuticle only let air and carbon dioxide to the tracheae.
Additionally, these gills can also be used to mislead predators. If the gills send out water in one direction, the nymph would be easy to track. Therefor the gills wave out water in all different directions of their body so a predator doesn 't know exactly were the mayfly nymph

Synthesis And Coloration Of Daphnia

1196 Words | 5 Pages

They create a well balanced ecosystem by being the prey of amphibians and small water insects and eating algae found in ponds and lakes. When there is not Daphnia present in lakes and ponds, an increase of algae and decrease of fish can be seen. Because of their sensitivity to the surroundings and its transparent carcass, when Daphnia are in hypoxic conditions, more hemoglobin is produced and they appear red. Hypoxic is when the body or part of the body is lacking adequate oxygen supply. This red color can be seen about

Essay On Daphnia Magna

187 Words | 1 Pages

Daphnia magna is a transparent water flea species found in rocky pools along the Atlantic Ocean. The Daphnia’s body is encased in a clear structure called carapace (Elenbaas, 2013). The exoskeleton, carapace, provides protection for the Daphnia magna, “The portion of the hard exoskeleton, or shell, that covers all or part of the body of many crustaceans…” (“Definition, n.d.). The heart can be easily seen under a light microscope due to the transparency of the skin (Handy, 2012).

Cray Fish Lab Report

677 Words | 3 Pages

We measured metabolic rate indirectly from the rate the crayfish consumed oxygen, which was expressed in terms of body mass. Because we were using more than one crayfish, and all crayfish had a different body weight, expressing the oxygen consumption rate per unit mass made it more reasonable to compare different crayfish. As our resulted had shown that there is no significant difference in oxygen consumption between the warm and cold acclimated crayfish, and oxygen concentration should decrease when water temperature went up, crayfish must increase their ability to pick up oxygen from the environment when acclimated to higher temperature. This was supported by Powell and Watts 2006 that acclimation affected directly the ability of hemocyanin to bind oxygen. This told us that hemocyanin, analogous to hemoglobin in vertebrates, increased their ability to pick up oxygen when acclimated to a higher temperature.

This is one of the reasons why it got the name – Coat of Mail Fish. The hardy body makes it difficult for predators to be able to consume it. Also, the body has been found to help it adapt to various environments prevalent in a tank. It is important to mention that this fish is sturdy and can withstand most diseases that attack other fishes. The Port and Starboard Lightfish is easy to maintain and it can feed on anything that you give to it.

Gold Fish Respiration Lab Report

In this experiment we are observing how colder water is associated with the respiration of goldfish. Respiration, also known as breathing, is the process in which the body exchanges gasses and supplies oxygen. Goldfish use their gills to receive oxygen and get rid of carbon dioxide. Oxygen is an essential part to life because it is broken down to create ATP. ATP gives the goldfish energy to carry out it’s everyday goldfish activities.

Roughly 34 million people in Canada and the United States live in the great lakes basin, and also 35 000 plants and animals, over 170 of those being fish, inhabit the great lakes (Zimmermann). This significantly large water body holds an estimate of 6 quadrillion gallons of water.

The Daphnia Magna Experiment

This laboratory experiment involving invertebrates is conducted to enable students to investigate Daphnia magna’s responses to external stimuli, therefore developing a better understanding and knowledge of homeostasis that occurs in organisms and the reaction and behavior exhibited by the daphnia magna when varying conditions are exposed to the organism compared to its natural environment conditions (Carter-Edwards et al, 2011). In order to understand the experiment, a foundation of information about the chosen organism such as its natural environment and physiology must be understood. According to Clare (2002) and Ebert (2005), Daphnia magna are small planktonic crustaceans belonging to the subclass Phyllopoda, found in lakes and

Tongue Eating Louse Research Paper

Also because these juveniles will choose just about any fish they can find, their temporary host might not be enough to complete their cycle. Either because of the size of the host or it’s susceptibility to predators. As the juvenile matures it will eventually look for a more acceptable permanent host fish in order to complete its life cycle and eventually reproduce. After the developed louse attaches to its permanent host and transitions into a functional male, the natatory setae which were used by the juvenile to swim, are lost. This is part of its transition to live in its new permanent

Now, artificial fly fishing flies come in many shapes and sizes. However, there are three main categories that can be distinguished, and those are wet, nymph, and dry bait fishing flies. When the fly population is in a terrestrial state, or living above the water, then a dry fly is typically preferred. A dry fly is the one that is intended to float. When local flies are living underwater, typically just after hatching and during the immature phase, fishermen should use a wet fly.

The second layer of fur is a lot longer to give it some protection, with more a bit more density to the fur of the Nutria. The outer layer of hair is only about 3 inches longer, covering up the nutria completely. The Nutria also have whiskers that can reach up to 4 inches long. The feet of the Nutria are webbed making them excellent swimmers, they also have a hind “thumb” that is not connected to the webbing.
