Introduction

Brine Shrimp are crustaceans which are distantly related to shrimp, crabs and lobsters. Brine shrimp live in salt water lakes because they can avoid predators; not a lot of aquatic life can survive in that condition. Brine shrimp have eleven pairs of legs used as gills. Their gills are used to help them breathe like lots of sea life, but these gills are also used to pump chloride ions, which take out the salt from their bodies and go into the water. You can tell the difference between a male and female brine shrimp easily. Males are usually green/blue, while the females are brown/red. The females have a sack of eggs along their body, and males develop a big and hooked clasper. The temperature of the brine shrimp tank was originally …show more content…

The control group was the tank where we did not add two ice cubes a week. Some constants that were the same between the two groups were the temperature of the room, the amount of food the shrimp were given, the initial temperature of the water, the pH level, the tank, the number of eggs the tanks start with, and the initial amount of water. If we add ice cubes to the experimental group of brine shrimp, then some will die and others will survive, but go into dormancy because brine shrimp are not good in cold …show more content…

We were also not consistent in the days that we added ice, and we even added it two days in a row one week which could have caused an error. We could have also gotten a bad bag of eggs which could have affected them hatching. A suggestion to improve this experiment is to make sure that the tanks start out identical, and so do the bags of eggs. You could also improve this by making sure you consistently add ice cubes in the same cycle. A follow up experiment I would like to do is to add an ice cube every day and see if we get different results then we did with this experiment- adding ice cubes twice a week. I predict that the population will stay the same, then start to decrease. In conclusion, the brine shrimp population increased when we added ice cubes in the water because it brought the water closer to their preferred

    Using the 0.1 M stock solutions of sugar, a 0.01 M dilution was created for each sugar type by adding water to the stock solution 9 out of 1. A 20 mL dilution was made for each trial. The same volume of each solution (10 mL -5 mL ) was added to the green sponges to create four group; Group 1: Sponge with 10 Ml 0.01 M glucose solution, Group 2: Sponge with 10 mL 0.01 M fructose solution, Group 3: Sponge with 10mL 0.01 M sucrose solution, Group 4 (Control): Sponge with 10 mL water. The four sponges were placed every 90 degrees on the edge of the arena. The isopods were placed into their environment for one to two minutes to acclimate with the environment.

    Students started off with a population of ten Skittlefish (skittles) on an orange reef (construction paper). The skittles had varying colors, and the adaptive trait being examined was the ability to blend in with the reef so the predators would not find them. The hypothesis that was thought up was that individuals’ survival was based on their location and coloring. The first year began with two of each color, and 5 Skittlefish were eaten that “year”. The ones eaten were two green, two purple, and one red.

    For temperature treatment, 89% of brine shrimps prefer Sec. 2, 3 and 4. This is a very high percent and does not show that species only prefer one specific environmental condition. For pH treatment, all four sections have species equally divided around the expected results. This is more evident where Chi-square test value (X2=19.91 with p≤0.05). For light, 90% of the species prefer Sec. 1, 3 and 4, each with different gradients of light shows that species are equally divided into all four sections.

    Its flaxen eyes are usually the only part of the cuttlefish that pokes above the ocean bottom. At nightfall, the cuttlefish comes out to feed on small shrimp and fish. Two long fins haunch the sides of the striped pyjama squid body and the arms of its two tentacles have small suckers, each having a toothed horny rim. The lower side of its body is veiled in small glands that let out slime when The Striped Pyjama Squid is under attack by predators, quickly scarring off or terminating any predators from harming it by any means. It can also quickly change color to a dark purple-brown, making it easier to screen itself against corals and rocks near the bottom of the

    Salinity Changes With Sheepshead Minnows Sheepshead minnows are one of the few fish that can survive in a big change in salinity and temperature. I would like to observe how long they can survive in a certain amount of salinity with small changes in salinity over time. I will slowly over five day period, take away salt from the sheepshead minnows tank. I will have twenty sheepshead minnows in all, ten in the tank having the salt removed and another ten in a tank with the same salinity as the water I found them in. This is important because we can learn how some animals adapt over time to live in different environments.

    Before getting the goldfish subjects, two beakers were filled with 200 ml fish water and weighed. Four goldfish were then collected gently from the fish tank and each two of them were transferred into one beaker. Each beaker along with fish and water was weighed again to determine the weight of each pair of goldfish. For the control group of each trial, the oxygen chamber was firstly filled with 200 ml fish water; after two goldfish along with 200 ml water were transferred into it, it was sealed in order to prevent oxygen exchange with the ambient environment.

    For the past 30 years marine scientists have found out that there is a relationship between the animal and the current, they have found out tat there is a circulation pattern for lobster recruitment. Around eight different types of cray fish is found around the western Australian coast, with most living around the area between Perth and Geraldton. Depending on the Leeuwin current and the pressure levels, the amount of cray fish is determined. The stronger the the current the more larvae will be transported near the coast. There are many cray fish larvae that is produced every year, but depending if it makes it to shallow waters or, near the coastal edge then the more or less juveniles will survive.

    Salt is what the brine shrimp need to hatch. Without salt the brine shrimp won’t be able to hatch or stay alive long. My question ‘Which water will the brine shrimp thrive the best in with with the different amounts of salinity?’This experiment will test whether it matters how much salinity is put in with the eggs.

    The first figure helped understand the location of the different tributaries in the upper Kiamichi River being used in the experiment. The first table helped highlight the point that the known range of O. saxatilis was shown to have increased and that the sympatric species P. tenius inhabits the same streams as O. saxatalis compared to the other sympatric species. Table 2 helped demonstrate that depth and flow velocity differed between riffles and pools especially between the dry and wet periods. This showed that the difference in water levels between riffles and pools could affect the habitat that the crayfish is living in and their preference for a certain environment. The other abiotic factors did not vary dramatically, which showed that they do not affect crayfish distribution.

Cowperthwaite positions the audience to feel sympathy towards the killer whales by making deliberate choices in sound, visual, language, and structure through the representation of trainers as unprofessional, and whales as mistreated, also experts as reliable information source. Firstly, Cowperthwaite uses effective language techniques to position the audience to view the trainers as undertrained and unprofessional.

    In addition, when crayfish were acclimated to 30°C, at least two unique acidic protein bands with isoelectric points (pI) ranging from approximately 4.6 to 4.8 were expressed (Powell and Watts 2006). Threrefore, the adding of acidic protein must have played an essential role in increasing the ability of hemocyanin to bind oxygen. Alteration in gene expression usually took days to happen, therefore crayfish that were acclimated to 20°C would be fine to acutely exposed to 10°C, because

    Sometimes the cuttle fish will use its arms to walk across the ocean floor to hunt food and to keep away from larger predators. Their favorite food is crab, but they also eat small fish, shrimp, and some are even carnivores. They have a fin like thing that goes around their bodies so they can swim. The cuttlefish also has an internal shell called the cuttlebone.
