Isopods Research Paper

Isopods are land dwelling crustaceans also known as pill bugs. In the lab the isopods will be studied on ethology which is the study of animal behavior. The taxis and kinesis will also be studied of the isopods. Taxis is when a certain factor attracts or repels an individual. Kinesis is when an individual randomly moves because of a certain factor.

The isopods used for this experiment range in color from gray to brown and were about 8.5 to 18 mm in length. Each Isopod’s head had one pair of antennae and one pair of antennules, both used to detect sensory stimuli from the environment around the pillbug. Their bodies were made of a hard thorax with seven segments and an abdomen. Each pillbug had seven pairs of legs, one for each segment of its thorax. Pill bugs breathe through gill-like structures and must live in moist places.

Introduction: Terrestrial isopods, also known as pill bugs, are comprised of a variety of different species and are known for their adaptability to different environments, which have certain wavelengths of light and sufficient water and nutrients to survive (Danielson et. al. 1976). They are usually found in moist, dark areas because they are extremely vulnerable to dehydration and need a sufficient amount of water to survive (Wagler et. al. 2013).

This cartoon goes by a few names, but the Standard Oil octopus is the most common, it was created by Udo J Keppler in New York and wad published in Puck magazine on September 7th 1904. The cartoon depicts a standard oil tanker as an octopus it has its tentacles wrapped around Congress, state capital, the shipping industry, the railroads, and other business owners or politicians. The only thing that the octopus does not have control of is the White House, its eyes are fixed on it but its tentacles are just hovering above it not able to grasp it, the reason for this is because of President Roosevelt using the Sherman Antitrust Act to regulate the monopolies. The point Kepler was trying to get across the importance of regulating Standard Oil to prevent them from monopolizing farther in controlling the entire country, which at the time they already pretty much did.

In our lab we were working with isopods, also known as pill bugs or rollie pollies. The isopods that we worked with were land isopods. They like to live in moist places under untouched objects such as boards, bricks, rotting logs and or rocks. Basically, they will live anywhere! If you are lucky enough, you can even find them next to buildings where it is moist and if there is food. All living organisms like certain things and don't like certain things, for example; most animals will try to eat something sugary or sweet, like a piece of candy. While the same animal my not wanting to eat something that is not sugary or sweet like peas.

Did you know that you share the same genetics as a mouse, or what about a fruit fly, and also a chimpanzee? In this paper I will be talking about how we share the same genes, and what the percentage is o the same genes we share with the 7 model organisms. I will also be telling important information on why we are related and how this all came to be.

These cephalopods have been studied and collected since 1990, but it's only now that researchers are considering naming them. Before a name can be given to a new creature, the entire structure must be analyzed to determine whether they are dealing with a new species or simply a related one. If it's a new species, the information is published in a scientific journal. What scientists do know is that the species belongs to the Opistotheuthis genus. This is an octopus species known for their smallish, condensed shape and webbed limbs.

They use their legs for flying and walking. They have six legs they have two forelegs, two middle legs, and two wind legs.The legs look like pincers. The wind legs are longer than the forelegs and middle legs.

The title of this project is Octopi, and is based on the original Pac-Man where the player controls the titular character through a maze while eating dots. When all dots are eaten, you progress to the next stage. Four enemies roam the maze trying to catch Pac-Man. If an enemy touches Pac-Man, a life is lost, and when all lives have been lost, the game ends. Near the corners of the maze are four larger dots that provide Pac-Man with the temporary ability to eat the enemies. The enemies turn deep blue, reverse direction and usually move more slowly. When an enemy is eaten, its eyes remain and return to the center box where it is regenerated to its normal color. A bonus life is also awarded each time the score accumulates 10k points.

In the 1880s, Antonio Berlese, an Italian entomologist, built a system to remove small invertebrates from soil samples. His first design was larger and much more complex than the system that we now make, but it worked in much the same way. Berlese funnels are used for extracting arthropods, an invertebrate animal having an exoskeleton, a segmented body, and jointed appendages (Bio 2 Book, page 684), from soil and litter samples. The earliest fossils with this particular body structure are from the Cambrian explosion (525-535 million years ago), indicating that the arthropods are at least this old. Berlese Funnels work on the principle of insects and other arthropods that normally live in soil and litter will respond negatively to light. Therefore, a light source is used to force the arthropods to move downward, where they will fall into a funnel and then into

They are cold blooded tetrapods having ability to live both in water and on land. *Two pairs ofpentadactyle limbs. However,some forms are limbless. *Skin is moist,glandular and devoidof scales (except gymnophiona). *Nostrils are paired. *Eyes with movable eyelids. *Skeleton is mostly bony.

Arthropods are animals with jointed legs, a segmented body, and an exoskeleton that live on land and in the water. Arthropods include arachnids, crustaceans, insects, and myriapods. Some well-known arthropods are spiders, scorpions, crabs, lobsters, shrimps, and butterflies. They live from the bottom of the sea to just about anywhere on land, even at the Antarctic. They have different predators depending on where they live. In the sea, they are preyed upon by seals, fish, birds and bigger arthropods. On land they are eaten by frogs, birds, lizards, mice, and larger arthropods. Humans also eat both kinds of arthropods, like crabs, lobsters, and even spiders. Arthropods eat fish and other meat, other bugs, fungi, bacteria, and plants.

Squids, an animal that lives in water, knowns as cephalopods. It also has a scientific name; Teuthida. Squids are capable of jet propulsion, walking, swimming and sometimes flying… Yes, flying! Jet propulsion! It has another definition when it comes to an animal that lives in water but it’s original physical definition is the jet of matter passed by the thrust produced in the opposite direction, to direction of movement. Furthermore, Newton’s third law states that the motion of body is propelled in the other direction of the jet. Jet propulsion occurs when the squid wants to speed up, their fins (Fig.1) propel themselves in water and then water gets in mantle cavity and above the gills, then reaches an opening by the head. The mantle cavity’s

Spiders can be found in all environments throughout the entire world, except in the air and sea. (Biology of Spiders, R.Foelix) These invertebrates of the order Aranea are one of the several groups of the Class Arachnida, with about thirty four thousand species.

There are two biological impacts during handling and storage of crustaceans such as oxygen and temperature. Crustaceans need oxygen to life. Besides, crustaceans have the ability to survive for some time out of water. However, when in air the animals may appear to be blowing bubbles, which they use to keep their gills moist and allow some exchange of oxygen. Meanwhile, this leads to a built up of waste products in the blood and gill chamber, which are released rapidly when the animal is returned to seawater. Storing the crustacean out of water will dry out the gills causing damage. It will prevent animals from recovering when re-immersed and this can result in high mortality. Crustaceans also developed a short term capability to cope with water that has low concentrations of dissolved oxygen. However, low levels of dissolved oxygen leads
