Mollusca Essays

Australian Giant Cuttlefish are in the following taxons, being ordered largest to smallest, Animalia, Mollusca, Cephalopoda, Sepioloida,Sepiidae,Sepia, lastly Apama. Their scientific name is, Sepia apama coming from their genus and species. Sepia apama is found about 100 meters under water around the southern coasts of Australia and Tanzania, in the seagrass beds of these coastal waters. Sepia apama typically eat small like crabs organisms called, crustaceans, and small fish. Sepia apama has predators

The Atlantic Horseshoe Crab is an amazing a unique animal. Despite it 's name it not really a crab. It is actualy more colsly related to spiders, ticks and scorpians. It is in the Animalia kingdom and is in the Arthropoda phylum. It 's most common name is the Horseshoe Crab but it 's scientific name is Limulus polyphemus. The Horseshoe Crab is not just found in Cape Cod, it is also found along the northern Atlantic coast and up the Gulf of Mexico. The horseshoe crab looks very round, it also has

Cephalopods, such as limpets and octopuses, played a significant role to help us understand how animals build their own civilizations. Martin Wells, the author of “Civilization and Limpet”, provided a series of factors throughout the essay to guide the readers, also presented the core of how civilization works by the contrasting the human to the cephalopods. Wells first investigated about limpets, finding a probable answer to explain how limpets could return to the exact spot after several hours

Echinodermata and Mollusca is the two common phylum in the kingdom Animalia. Echinodermata consist of five large classes which are, class Crinoidea, example feathers star, class Asteriodea, example star fish, class Ophiuroidea example, brittle star, class Echinoidea, example sea urchins and the class Holothroidea, example sea cucumber. Phylum Mollusca consist of six major classes, which are Monoplacophora, Gastropoda, Cephalopoda, Polyplacophora, Scaphopoda and the last class which is the Bivalvia

My First Box Turtle About three years ago I had a female Eastern Box Turtle. She was maybe as big as a small paperback with an orange stomach and a hazelnut color with brown plates colliding into each other making a hard and sturdy shell. Her extremities were scaled but rough; each scale had an orange underside that matched her smooth underbelly. Her face was wrinkled and her eyes were red rimmed. The most obvious detail was the large white patch in the center of her shell from a distance looked

Name: Jewel Ward ID: 812004483 BIOL 2262- Evolutionary Biology Lab # 3 – Fossils Aim: To study fossils and the sedimentary layers they were found. Examine the clues left to appreciate the species found and the characteristics of the environment at the time when the organisms died and became fossilized. Introduction: Fossils are the remains of organisms that are formed when those organisms died and become buried in such a way that the decaying process was slowed down due to environmental conditions

Sexual reproduction is most common type of reproduction among the plants and animals. They are of following types; 1) Syngamy: The fusion of gametes takes place completely, if male and female gametes are produced by same cell or organism and both gametes fuse together to form a zygote, this is called as Autogamy, paramecium is its example. Another is Anisogamy in which some organisms produce two types of gametes. Both types of gametes differ from each other in their shape and size and are known

The following analysis is a comparison of two marine animals, octopus, Octopoda, and the moon jelly, Aurelia aurita, and how their nervous systems differentiate. Octopus have bilateral symmetry and jellyfish have radial symmetry which correlates to their body functions. Both species behave differently but share similar features, although they are not related and have unique developments which evolve over time. The two species to be compared are the octopus, Octopoda, and the moon jelly, Aurelia

Common name: Giant African Snail Description: Compared to other snails, the A. fulica is bigger, can be up to eight inches tall and like any other organism in the mollusca phylum possess a shell. The shell is shaped in the form of a cone and has up to nine swirls of color adorning it. The color of the shell ranges from dark brown and reddish brown. Additionally, the shell can be decorated with streaks and marking that can be dark or light in color. Although the color of the shell mainly depends

Arthropods and Molluscs, although both common in harsh coastal environments, in fact do not share many similarities due to the differences in their adaptations to their environments. Arthropods are described as segmented coelomates that have jointed appendages whereas Molluscs are coelomates, but have neither segmented bodies nor jointed appendages. By animal classification, both Arthropods and Molluscs have bilateral symmetry, are tripoblastic (having three layers of tissues in tissue development

1003939759 Week01 Thursday 1:30-4:30 Qing Rui Teng Jalina Bielaska Da Silva #15 Blue Safety Rings: a study of colour pattern variation in the greater blue ring octopus (Hapalochlaena Lunulata) in Australia. Introduction Sea dwelling organisms are often faced with the danger of predation, thus many marine organisms had developed some forms of self defence or rather forms of protective measurements against predators. The greater blue ring octopus (Hapalochlaena Lanulata) possesses one of the deadliest

The octopus has captured the attention of the science world in the past few decades. These elusive sea-dwelling creatures mystify us with their behaviors that indicate intelligence. Researchers are perplexed by octopuses’ complex behaviors; octopus demand our ongoing attention because the more we look at them, the more questions we formulate. Octopus force us to question our definition of intelligence. They push us to realize that we might not be the only creatures that have the ability “to solve

Aquaculture is the harvesting and breeding of organisms in water environments. There are two different kinds of aquaculture which are for freshwater and saltwater species. Aquaculture is used for many different things such as food, jewelry, restoration and the making of commercial products. In the United States, there are many different types of organisms that are involved in cultivation. These organisms consist of things like mussels, oysters, sea bass, shrimp, clams and so much more (NOAA). In

DISCUSSIONS Life and Climate during Mesozoic Era According to the International Commission on Stratigraphy’s International Stratigraphic Chart (ICSISC, 2008) the Mesozoic era or the “Middle Life” is divided into three periods: the Triassic which spans from 251-199.6 million years ago, the Jurassic which spans from 199.6 – 145.5 million years ago, and the Cretaceous which spans from 145.5 -54.5 million years ago. During this time the climate is hot and tropical worldwide. The Earth is continuously
