Exam 2 Colette Cabaniss Student K00479544 (colettecabaniss@yahoo.com) login:fireant Question 1 Echinoderms are captivating organisms. They have a number of specialized structures and functions. They have unique water vascular systems, aboral surfaces, and feeding structures. This sets them apart from other animals because of their distinct characteristics. The water vascular system of echinoderms is a hydraulic system that they use for respiration, getting rid of waste, and a way of movement
The Life of a Brittle Starfish The type of marine organism, which will be reported on within the following text, is the Brittle Stars. The Brittle Star is also called the serpent star and a common name for a large group of echinoderms closely related to the starfish. These organisms make up the class Ophiuroidea; another common name for ophiuroidea is snake stars. These organisms can be found in all oceans but are more abundant in the Tropics. Brittle stars can come in different colors. 2.0
Echinoderms (scientific name Echinodermata) are a major group of only marine animals. The name comes from the Greek word for "spiny skin". There are about 7,000 species found usually on the sea floor in every marine habitat from the intertidal zone to the ocean depths (Marine Education Society of Australasia 1999-2015). They occur in various habitats from the intertidal zone down to the bottom of the deep sea trenches and from sand to rubble to coral reefs and in cold and tropical seas. Some echinoderms
Echinoderm (meaning Spiny skinned) is a diverse group of invertebrates belonging to the phylum Echinodermata. Phylum Echinodermata consists of five main classes that are divided into 7,500 extant species and approximately 13,000 known extinct species, including several classes that were discovered through fossils. The five main classes are proposed to have evolved from a common metazoan ancestor approximately 500 million years ago during the early Palaeozoic period (Britannica, 2014). Echinoderms
system in the body by which blood and lymph are circulated.” - Boundless Textbook. In other words, a heart is not required to be a part of the circulatory system. The human circulatory system has a more complex physiology and anatomy compared to echinoderms. Humans have a system that circulates through the body through millions of blood vessels, delivering oxygen to cells that require the substance. The system is consisted of a heart, lungs, different
Annelids: I learned that the phylum Annelids can consist of many creatures such as earthworms, leeches, and scale worms can adapt to a variety of environments. Annelids’ bodies are divided into segments which are seen as rings by the naked eye. They have muscles which help them move by contracting their longitudinal and circular muscles. When Annelids take in food, the food particles travel through one end of the body and are excreted out the other side. The video enhanced my understanding about

of this a small quantity of animals are capable to live in this areas and the animals that accomplish this difficult task usually has some adaptations that allow them to survive. Some animals present in the abyssopelagic zone are some species of echinoderms such as sea cucumber and pig-fish, some types of squid and arthropods like the sea spider. The adaptation that some species of squid have is the coloring transparent of their body allowing them to become invisible to their prey in dark environments
The Permian Triassic Mass Extinction The Permian Triassic extinction was an event of cataclysmic disaster and almost the extinction of all species on planet earth. The Permian Triassic extinction is said to have occurred millions of years ago, geologist have estimated that its occurrences happened about 248 million to 286 million years ago. This rare occurrence of events proceeded the Triassic geologic periods and the Paleozoic and Mesozoic eras. This mass disaster was the largest dissipation
likes to live in shallow waters that are only 2 to 12 meters deep off the coast of Sulawesi, Indonesia and is restricted to this area. More specifically, it can be found at river mouths in the sand substrates, a habitat that flourishes in fauna, echinoderms, fish, crustaceans, and copious amounts of burrows and mounds. The mimic octopus has a striped coloration and, like all octopi, the mimic octopus has 8 arm-like appendages, a globe-like head, and can change the p...
When we look up to the night sky, there are beautiful, sparkling things that can not be taken away to make a wonderful gorgeous night. There are the stars and the moon which make the night sky shining, shimmering, and have inspired people to paint and discover their special features. On the other hand, we also have stars which are close to us and are as fascinating as the stars up in the sky; they are called: sea stars. Sea stars used to be known as the starfish because aquamarine scientists have
The Truth of Jurassic Park Jurassic Park is an action packed movie based around the recreation of dinosaurs, but the dinosaurs are all female to control birth. The dinosaurs were created by DNA from preserved insects in ancient amber. Because the DNA is so old, sections of chromosomes were not there. To patch the empty spots, the scientists used frog DNA. In the movie, one of the scientists, Malcolm, says that controlling the dinosaur population by having only females will never work, and that nature
create Calcium Carbonate (CaCO3). This calcium carbonate is used to make up the hard shell coatings of many marine organisms from small plankton such as coccolithophores and phytoplankton, to larger organisms such as mollusks, crustaceans, and echinoderms. The biological pump can mostly be explained as the cycling of these organisms and their shells. When an organisms dies, the fixed carbon from its soft or hard tissue is mostly contained in the upper lev... ... middle of paper ... ...on of drawing
adapt had the opportunity to pass on their genes. Those that could not, died off and became extinct. Because of early organisms' ability to adapt, many of the animals alive 543 million years ago, in the Cambrian Age, are alive today. Animals like Echinoderms, now the modern starfish and sea cucumber; annelids and priapulidas, now worms; chordates, mammals and anything with a backbone; arthropods, including insects and spiders, crustaceans and scorpions are such animals that have been evolved from early
the world's ocean surface, they support over 25% of all marine species on earth. They provide complex and varied marine habitats that support a wide range of other organisms including, but not limited to, fish, mollusks, worms, crustaceans, echinoderms, sponges, tunicates and other cnidarians. Some of these animals feed directly on the corals, while others graze on algae on the reef. The reef also provides a protective habitat for many of these animals. In addition to their tremendous ecological
The Red King Crab’s scientific name is called Paralithodes Camtschaticus. The crab is the ancestor of the Hermit Crabs, and as well as many other crabs (A-Z Animals). The red king crab both live in Alaska, the Northern Pacific Ocean, the Sea of Japan, Northern Kamchatka, the west coast of North America, southern of Queen Charlotte Island, and the Southeastern Bering Sea. The adult red king crabs live in the Intertidal Zone and they prefer mud and sand. The king crab lives underwater on the sand,
According to Campbell and Reece (2007) biogeography is the study of the past and present distribution of species. Cristopherson (1994) states that it is the study of the distribution of plants, animals and related ecosystems and the geographical relationships with related environments over time. It involves a wide range of disciplines such as biology, geology, geography and ecology. It begs the question, why are there so many more species in tropical rainforests than in woodlands? What allows a species
INTRODUCTION: The Animal Kingdom is generally believed to have originated in Archeozoic oceans long before the first fossil record. Every major phylum of animals has at least some marine representatives; some groups, such as cnidarians and echinoderms, are largely or entirely marine lives. From the ancestral marine environment, different groups of animals have invaded fresh water; some have moved onto land. There are over a million described species of animals. About 5% of this number are consists
planci on the Great Barrier Reef The organism Acanthaster planci, commonly known as the crown of thorns starfish, has a drastic effect on the health of coral reefs all over the world, including the Great Barrier Reef of Australia. This poisonous echinoderm feeds upon the coral, and although this should be a healthy and natural part of the ecosystem, the population explosions of the starfish have caused devastation in many portions of the Great Barrier Reef. Reef sections take anywhere from ten to
Marine Biology of the Jurassic Period The Jurassic period is known as one of the most interesting periods of time in earth’s history, mainly for the awe-inspiring creatures many of which have gone extinct, the most remarkable being the dinosaurs. Life in the ocean during this time was also extremely diversified and amazing for the creatures it beheld. The Jurassic occurred from 199.6 to 145.5 million years ago, following the Triassic Period and preceding the Cretaceous Period within the Mesozoic
