They have tube feet on the underside of their bodies which allows them to move around. This starfish has two stomachs the cardiac stomach…

The crown of thorns starfish (Acanthaster planci) , a large multiple-armed starfish that prays on hard coral polyps, can be found in and throughout the Indian and Pacific Oceans. Some predators of these species are Giant Triton snail, the stars and stripes pufferfish, titan triggerfish and the humphead maori wrasse. 2.2 What causes COTS outbreaks: The cause of Cots outbreaks are not 100% certain but one of the most widely accepted hypothesis is that the outbreaks of COTS are caused and…

“The Blue Lankia starfish is so distinct when It comes to salt water that you can’t find those anywhere else. I got started around 1992 and the country was in a recession and there were really no jobs, especially for ex-military. Diving was a passion of mine and this hobby was a passion of mine, so I was able to keep things that others weren’t able to keep and I had special permits from the government to keep things that weren’t typically allowed just to see if we could keep them alive to pull…

The Crown of Thorns starfish (Acanthaster Planci) Anjali Barnes 2016 Ms. Lee 9X Acanthaster planci Introduction The Crown of Thorns starfish, or Acanthaster Planci, is one of the largest threats to the Great Barrier Reef. The starfish, also known as COTS, can have up to 21 arms, each with hundreds of toxic spines. They move by expanding and contracting these feet, and feed on hard coral. Abiotic features are non-living or physical factors and can have a large effect on the Great Barrier Reef…

Methodology Crab, lobster, snail, sea sponge, starfish and jellyfish are the six organisms that were studied. Using observationational skills, the organisms were located and collected using a dip net. All of the specimens live in salt water habitats, with crab being found both on land and in the water. Starfish are bottom dewellers and found ether on top of, or slightly buried under the sand. They can be located by shuffling…

Introduction The purpose of this lab is to discover the respiratory and circulatory systems of three different species: the Starfish, the Bullfrog, and the Perch. All of these species have similarities and differences and is discussed in detail in this research report. In order to determine the respiratory and circulatory systems, a dissection of the three species is needed to obtain data. Determining the systems of these species will help understand how these species work and work together in…

population of crown of thorn starfish, natural predators of coral, certainly doesn’t improve the situation. These large creatures invert their stomachs onto the coral so that they can digest the coral as they move along, leaving traces of white skeleton in their path. Humans can’t be responsible for this factor, can they? Unfortunately, we are. Our immense contribution to the ocean’s unnatural contents has created an ideal habitat for the over reproduction of the crown of thorn starfish. Runoff…

A short YouTube video by Hank Green provides an easily understood run down of evolutionary adaptations. Green gives examples of evolutionary traits in starfish, octopi and humans. For starfish, Green uses the evolution of the starfishes’ eyes. Some species of starfish have evolved eyes that allow them to find food more easily than those species that have evolved without them. Green also relates how some octopi have evolved with copper and the protein hemocyanin in their blood which combine to…

Earth is a precious resource, for it is home to many amazing, unique habitats and species. In current times, there has been troubling news that human hands are destroying many creatures and areas. Sources of the damages include air pollution from production activities and deforestation. When a specific environment is impacted, there is a long-lasting change. For example, when a home is demolished, the inhabitants do not have a place to go and will likely lose protection from prey. An ecosystem…

My Responsibility to America At a young age, my parents taught me what it meant to be responsible.They told me that being responsible for something is a way to show respect and appreciation for what you own. For starters, I was given jobs around the house, which my parents told me was my way of showing appreciation for the home I was provided, and it was my responsibility as a member of my family. America is also my home— a home which other brave Americans have paid for and founded. In return,…
