Overfishing

Introduction Marine invertebrates in the class Anthozoa are known as Corals. These diverse organisms give quite a show in the shallow clear parts of the ocean. Corals live closely together in groups expressing their bright colors that stand out so nicely. Many people consider coral reefs to be very diverse and productive than anything on land. Their skeleton is made out of calcium carbonate protecting them from future encounters with predators. Many more coral polyps then can attach themselves…

For my senior project, I decided to research water pollution, and how it affects ocean life and its inhabitants. I will be answering questions that I have about water pollution and how it 's affecting our oceans. The reason I’m doing my project on this topic is because I find it very interesting, and I also want to bring awareness to this issue. It 's a worldwide problem that needs to be addressed, because if we continue to do nothing, I believe that ocean life as we know it will go extinct.…

Hawai’i is known as the endangered species capital of the world with the largest number of endangered species per square mile than any other place on Earth (Meditz et al., 2013). Hawai’i is called this because of an invasive algae called Gracilaria salicornia, or gorilla ogo. Studies on Gracilaria salicornia provide background information of on the specific algae. Current research also analyzes the ecology of the algae, along with how the algae affects Hawaii's economy. Additional research…

engineer and writer of Scientific and Educational Publications talked about the shark numbers in the ocean and that the “populations of dusky, oceanic whitetip, and silky sharks in the Gulf of Mexico have declined by 79% to 97% since the 1950s due to overfishing. Massive declines are also reported over the same time period for blue, mako, oceanic whitetip, silky, and thresher sharks in the tropical Pacific Ocean” (“Threats to Aquatic Environments”). As the fishermen continue their job the…

Rudraksh Kapil Topic Area: Biodiversity Loss of biodiversity: what are the causes and what can we do? Biodiversity is the variety of all forms of life on Earth - plants, animals and microorganisms. Biodiversity refers to: Species; Variations within species; and interdependence of species.

A range of factors and…

Their extended bodies are surrounded by bony rings with small gill slits (Zubi, 2004). Their fin patterns and distributions are different than those for other bony fish. They have no pelvic fins, small pectoral fins, and one dorsal fin (Zubi, 2004). The pectoral fins turn the Seahorse and aid in steering, while the dorsal fin moves it forward. The coronet of the Seahorse is its most distinctive feature, helping in identification as the thumbprint does for humans (Zubi, 2004). Seahorses are…
