The Influence Of Shrimp

AP Biology Lab Report: How the Amount of Motor Oil Affects Hatching Viability of Brine Shrimp Eggs

Brine shrimp have survived successfully since the Triassic period, around 200 million years this has been possible through their unique adaptations which have enabled them to avoid predators and suit their environment. They are pretty good at surviving except in space (who knew radiation isn’t good for shrimp). One of the best adaptations the brine shrimp have is their ability to survive in waters of very high salinity (up to 25%). There optimal levels of salinity are 3-3.5% but they are rarely found in waters below 6-8% salinity for the same reason this adaptation is so good, no predators occupy waters with this level of salinity. With this adaptation they are protected from much predation and have very few predators except for birds. Another reason there environment is good for their survival is that it is so widespread. Salt water lakes are found all over the world.

Brine Shrimp are a micro-crustacean that is found mostly in inland saltwater bodies, however, the salinity levels that they live in vary greatly. The conditions that they require can be made at home as the eggs (cysts) of the shrimp are dry, hard shells that can withstand drought and go without water for up to 50 years. This study presents the results of 3 different salinity levelled environments to the Brine shrimp in order to discover a salinity level that produces the most successful hatching rate. By filling 3 Petri dishes with 20mL’s of purified water, each dish contained varying sodium chloride amounts from 15ppt, 25ppt, and

Crawfish are delicious crustaceans that closely resemble lobsters. Many people consider crawfish to be as delicious as lobsters, which is why these crustaceans are harvested all over the world. In the U.S., crawfish are closely associated with the haute cuisine and culture of Louisiana. In fact, crawfish are the official crustacean of the state. I normally prefer to harvest or purchase crawfish on the day I intend to cook them. However, many people prefer to purchase and eat them later but do not know how to keep crawfish alive in a sack or container for several days before finally preparing and eating them. Fortunately, I will provide you with some tips on how I keep my crawfish fresh and healthy

Adapted for a wide range of aquatic habitats, various shark species inhabit shallow coastal habitats, deep-water ocean floor habitats, and the open ocean. With a wide selection to feed off of, as a whole the shark species feed on just about everything. Their diet consists of fish,

Behavior of Brine Shrimp in Habitat Selection Introduction: This experiment was developed primarily to find the optimal or preferred living conditions of adult brine shrimp. In this lab 3 variables were tested in different degrees to determine which the shrimp prefer. The different variables were light, ph, and temperature. From outside resources I have found that brine shrimp can survive in temperatures ranging from 4° Celsius to 40° Celsius with an optimal temperature of 20°-25°. So I hope to reinforce this research by testing its validity in the lab. From another outside source brine shrimp display positive photo taxis, which means that they are attracted to light. And finally from my last outside source I have found information that

Reaching a length of up to 5.5 centimeters (or about 2 inches), the bigclaw snapping shrimp is the largest member of the family Alpheidae, which are also known as the pistol shrimp. It is found in water up to 30 meters (98 feet) deep from as far north as North Carolina’s Outer Banks to the Brazilian coast. It also is able to survive in areas of rapidly different salinity; A. heterochaelis has be found in environments that range from mesohaline (having a salinity of 5 to 18 parts per thousand) to hyperhaline (having a salinity of 40+ ppt). This means that it lives in environments that range from brackish to seawater of above average salinity. It is most commonly found in areas where cover can be easily found during the day, such as an oyster reef.

Daphnia are Crustacea. Crustacea are animals that have ten legs, four antenna and two main body parts. Most live under water. Some examples of Crustaceas are Crayfish, Shrimp, and Crabs. Daphnia are filter feeders. They eat small particles of algae and bacteria. Some are carnivores and eat other water fleas. Daphnia live in fresh water places such as ponds and lakes. They are found living in the vegetation or near the bottom of the body of water.

Carl hurried through the streets of Boston, his Red Sox baseball cap pulled low over his eyes to cover his graying hair and his mail clutched tightly in his fist. He strode into his cramped apartment and paused in front of the pile of blank canvases leaning against the couch, collecting dust. Carl hadn’t worked in days. His profession wasn’t the kind to call and demand that he return to work. Though he loved the atmosphere of the city, he didn’t envy the life of suits and corporations and business meetings. He preferred to create and, luckily, he was not unsuccessful.

The last things that have some effect on the shrimp habitat is the weather. For the last two to three years we have been in a drought. This can also cause the stream or creek to been dry up or low on water. When the stream dry up can cause the whole habitat to an end. Also when we in a drought with little to no rain the shrimp can’t survive due to the water is not moving from other end of the stream. The water is not moving then the shrimp doesn’t have a lot of food source to eat.

There are many different creatures in the ocean. They are categorized into 3 different groups that are Zooplankton, Nekton, and Benthos. In the ocean the zooplankton eat phytoplanktons. Zooplankton are eaten by all of the larger animals. Phytoplankton self reproduce so they don’t need to eat other things. They create their own food. The Nekton eat the zooplankton because it is a smaller species than the rest.

The complex eyes and polarized vision of the mantis shrimp has influenced a group of researchers to create a camera than can detect various forms of cancer. Polarized light is a light that radiates in different planes of direction, similar to looking at a white wall and a black table and can be used to see things the human eye can’t, such as cancer cells. Research conducted shows that its sensor has the ability to detect cancerous legions before cells can become abundant enough to appear as visible tumors. Associate professor of computer science and engineering at Washington University, Viktor Gruev, whose lab worked on building the sensor, says that polarized light makes it easier to see cancer cells because their disorganized and invasive

Found in shallow, tropical waters is a little crustacean known as the “mantis shrimp” even though it is neither mantis nor shrimp. More specifically known as “stomatopod” (or scientifically as Odontodactylus scyllaru [1]), this combative sea dweller is well known for its high-velocity punch. Its bullet-fast clubs have been witnessed to cause water to boil with visible flashes of light and release air bubbles that “[unleash] tremendous amounts of energy [2]” when collapsed. Even more unbelievable is its legendary feat of breaking aquarium glass measuring a fourth of an inch thick: an accomplishment achieved in April 1998 [2] by a specimen named Tyson. However, the mantis shrimp is not just a formidable fighter; it is also able to see like almost

The LDH activity for mako sharks was 1050.7 ± 72.3 (Dickson, 1993). Which is close to what lizard fishes LDH activity was (1131 ± 221). Mako sharks can be found at great depths in the ocean and so can lizard fish (MarineBio, 2015). White muscle in elasmobranchs uses anaerobic metabolism during burst of energy that causes them to move quickly (Dickson, 1993), which could be how lizard fish use anaerobic metabolism as well. Blue sharks LDH activity was 149.1 ± 19.1 (Dickson, 1993). Shrimp have the closest LDH activity to blue sharks with 134 ± 30). However, blue sharks tend to be found in the open sea, whereas shrimp are normally found in shallow waters (Vandeperre et al. 2014). Blue sharks are very large (100-225 cm) compared to shrimp (5-6

The Berkeley prawn that has been an iconic structure since 1992 has been demolished, despite locals running a public campaign to preserve it.
