The 11 armed sea star lives in South Australia , new Zealand and in the cape peninsula .it’s the largest seastar in southern australia they are found under rocks,algae in pools and in low water levels. It eats oysters,mussels,snails,shrimp and other starfish. It’s scientific name is the Coscinasterias calamaria . it could be brown, blue , green , grey, mauve,white,cream or orange. It you cut off one of its arms it will grow into a new starfish. It’s arms could grow to be up to 30 cm. 11 armed…

warmest seas to the coldest oceans off the coast of Antarctica. Because Sea Urchins are edible you may be able to find a sea urchin on the menu in a sushi restaurant. Sea urchins mostly eat kelp that they find nearby, but occasionally they will eat algae, sponges, or muscles. The Sea Urchin isn’t extinct because of its reproduction process. The way Sea Urchins reproduce is very complex and Sea Urchins can have a very long lifespan. The female's role in reproduction is to mate with a male…

also causing carbon levels in the ocean to get too high and is leading to ocean acidification, which leads to coral bleaching. Coral bleaching is when the algae living in the coral tissue can no longer survive due to too much carbon in the water. Without the oxygen given off by the algae, the coral then becomes sick and can’t survive. If the algae is not able to regain its population in that reef it soon dies.Global warming is also creating dangerous heat waves, severe droughts and extreme…

Polluted runoff is water from rain or melting snow that runs across the paved land instead of seeping into the ground and being filtered naturally. It happens with the water that flows off of our streets, parking lots, and building rooftops and it picks up all kinds of hazardous waste like pet waste, debris, manure, pesticides, oil, and automotive fluids. If the runoff is poorly treated or untreated, it negatively affects the water quality and the aquatic life in the local streams, then the…

Dinoflagellates are marine plankton, they are producers and have eukaryotic cells (meaning that the cells have a nucleus). Diatoms are unicellular, they are a type of algae. Cleaner shrimps free other organisms of parasites. Copepod are small crustaceans found in marine ecosystems. Ptereopods are a type of sea snail/slug. The type of squids, sharks and small fish found in a marine ecosystem depend on the abiotic elements…

organism. Most of the organic matter in lakes is in the dissolved form. The suspended matter caused the light scattered and absorbed rather than transmitted. Turbidity of water also affected by water current or wave action and it can cover the benthic algae with muddy sediment and deprived them of light. However, turbidity is not a measurement of the amount of suspended solids particles presents or the rate of sedimentation in a stream. It measures the scattering of light by the suspended…

Some fish eat plant life. They may scrape algae off rocks or eat plants that grow in the ocean or sea. Some fish, called predators, prey on other fish and animals. The fish of omnivorous category feeds at the ocean’s bottom contains a mixed diet. They’re naturally opportunistic and survive on nearly…

dioxide, water vapour and hydrogen compounds such as methane and ammonia. Within million of years life evolved in the oceans. 3.2 billion years ago photosynthesis had evolved with the first oxygen producing cyanobacteria, similar to today’s blue-green algae. At first, the oxygen given off simply reacted with the rocks, but gradually it built up in the oceans and started to bubble out into the atmosphere. To start with, it was a toxic gas harmful to life, but soon life evolved to make use of the…

I chose the topic, Geology: Understanding Fossils. I’ve always been fascinated by fossils and where they came from, what we can gain/learn from them. My source for research is below, used via Google Scholar. Fossils - why are they important? This is a great question that a lot of people should be well-informed with. In the mission to seek out and discover fossils, we learn a lot about why this is important and where it all started. In the book, “Discovering Fossils: How to Find and Identify…

Eutrophication is the process which causes ecosystems such as lakes and rivers to increase in fertility due to a higher level of nutrients entering the lake or marine environment (Mayhew, 2015). This results in a growth of plants such as algae. As these algae plants die, aerobic and anaerobic bacteria cause decay, therefore use up the oxygen within the marine environment (Credo, 2015). Eutrophication has significant impacts on water quality of rivers and lakes within the Waikato region. Although…
