Phylum Hemichordata Research Paper

Dallin Ashby, a graduated UF entomology master's student, normally spits crickets with his 11-year-old son Myles Ashby when they participate in BugFest. But this year, his 8-year-old daughter, Eliza Ashby, said she was going to try too.

In the article, “Is Drinking Alcohol While Pregnant an Unnecessary Risk to Prenatal Development,” Phyllida Brown believes that drinking is bad for pregnant women and can put the baby at risk for Fetus Alcohol Syndrome (FAS) (76). She supports her claim by providing follow-ups on children whose mother consumed alcohol during pregnancy. The children whose mother consumed alcohol, tend to be more aggressive and had a hard time focusing compared to children whose mother didn’t consume alcohol. Some physical traits that children with FAS have are thin lips and tend to be smaller than the average kid (Brown 76). Brown also supports her argument by using a counterargument about how some women claims that it is okay to drink wine or alcohol every once

On this image, we see the external dorsal side of a preserved crayfish. As part of the largest animal phylum the Arthropoda, the body of the crayfish is segmented, with jointed appendages and exoskeleton. The paired antennae (1) are long appendages located the front of the mouth and modified for help the animal to sense touch and taste. The antennules (2) are shorter, also paired with the same function but they also help to maintain balance. The chelipeds (3) are located on the front of the thorax, and they are responsible for defence and grasping food. On the at ventral part of the thorax, we found four pairs of walking legs (4), with these legs the crayfish changes locations on the bottom of freshwater lakes, streams and also on land. They

The materials needed for this lab were: a light microscope, lamp (if needed or available), microscope slide, coverslip, tweezers, preserved insect leg (or a parakeet’s

The signs are plastered where everyone can see, “Clean, Drain, Dry your boat!” these words have become so well known, we are starting to forget their importance. The invasion of Zebra mussels into America’s waters has tremendously grown over the past several years and now, we are finally able to turn the tide on these treacherous creatures.

Horseshoe crabs are considered “living fossils” or evolutionary survivors because the external appearance barely changed in over 150 million years. The horseshoe crab is part of the arthropods, which include organisms such as spiders and scorpions. The horseshoe crab is made up of the prosoma, which is the head, opisthosoma, which represents the central part of the body and the telson, which is the tail. The tail is harmless and is only used to help the crab flip itself over if it’s turned over on the wrong side. Horseshoe crabs have been researched numerous times. Findings include their, ancestry, survival, morphological changes (if any) and phylogenetic research among the different variations of horseshoe crabs.

The most prominent fossils in the Crato Formation are the insects that are preserved. One example of an insect that has been recently found is the Araripenymphes seldeni (as seen in figure 3), an extinct species of lacewing (Myskowiak et al., 2016). The taphonomic classification of A.seldini is: Nymphidae Family Neuroptera Order, and Insecta Class (Myskowiak et al., 2016). This particular species shows sexual dimorphism, a difference in characteristics beyond the sexual organs (Clarkson, 1998). In particular, differences in the wing colouration and wing lengths (Myskowiak et al.,

In my ecology project the invasive species that interested me the most was the zebra mussel. In this report, I will be addressing the negative impacts that zebra mussels have on an ecosystem and the positive impacts of human actions on those ecosystems.

For the farmers of south east QLD (Australia), Barbers Pole worm is the main worm internal parasite infecting their sheep. This is due the amount of rain and the summer heat. Due to the weather and the climate of south east QLD, makes it the perfect environment for the Barbers Pole worm to infect the sheep. The Barbers pole life cycle is as so, once the barbers pole worm has laid its eggs in the stomach of the sheep, (barbers pole worm can lay up to 10,000 eggs per day), the worm eggs move through the digestive track and are mixed in this the fesses, the fesses are pooped out and into the land, the eggs hatch within 4-10 days, they will hatch faster in hot climate and slower in cold. Once the eggs have hatched they begin to feed on the bacteria

In incomplete metamorphosis there are few changes in internal structures which make larvae and nymphs anatomically resemble to adults and consequently they have similar feeding habit and behaviour. The only difference is the size and maturity of theses organs.

Lamprey are classified as hagfish. Lamprey are eel-like scale less animals that can grow up to 6 to 40 inches long. The skeleton of a lamprey consists of cartilage. The mouth is a round sucking hole surrounded with horn shaped teeth. They have eyes, one or two dorsal fins, a tail fin, a single nostril on top of the head, and seven gill openings on each side of the body. Lamprey live in coastal and fresh water. Not all lampreys spend time in the ocean. Some are landlocked and are stuck in fresh water.

Exogenous feeding signals trigger the transition from prolarval to larval stage. The anal plug is shed and the post-yolk sac larva (22 mm) can be identified by the prominent lateral band extending the entire length of the body.

The kingdom Animalia means animal. The phylum Chordata includes animals with vertebrates. The class Chrondrichthyes includes cartilaginous fish, which are fish that has a skeleton made of cartilage rather than bones. The family Lamnidae includes sharks as the white shark and mackerel sharks. These sharks are usually very large and can swim really fast. The genus is the group before the species which includes other sharks that are very similar to the white shark. The species is the last group, which contains the Latin name of the specific organism. Through taxonomy, scientists are easily able to identify and classify species.

In the Pacific Northwest on the Eastern side of the Olympic mountain range there can be found an animal that you would normally think would be found in the waters of the oceans, but here they are in trees, this is where you can find the Tree Octopus. They can be found on the Northwest side of the United States in on the Eastern side of the Olympic mountain range, adjacent from the Hood Canal. They live in this area because of the moistness of the trees and how their skin is they are able to easily adapt to the conditions of the rainforest. They also have the largest brain to body ratio compared to any mollusk of its kind (Zapato).

Paragonimus westermani’s Taxonomy is Eukarya (Domain), Animalia (Kingdom), Platyheminthes (Phylum), Trematoda (Class), Plagiorchiida (Order), Troglotrematidae (Family), Paragonimus (Genus), and Paragonimus westermani (Species).
