Bull shark

who has found (and continues to find) new sharks, I jumped in….to the story, not the ocean. Apparently, Dave Ebert travels to Taiwan because of a certain fish market. That market has dished him at least 10 new sharks, not yet documented. However, what’s really weird to me is that sharks have been around way longer than crocodilians. They have outlived dinosaurs. Sharks have been around for 450 million years. Here are some of my personal favorite sharks… The Frilled Shark I think all shark lovers know about the rare —supposedly extinct— frilled shark caught in Japan. Being a bottom feeder,…

You have probably heard of the Great White Shark and the Bull Shark. They are some of the scariest ocean predators. These two are in some ways similar, but they are very different, too. You will want to know how to tell the difference between the Great White and the Bull shark. To tell these two sharks apart, just see how different and similar they really are. There are some similarities between the two sharks like color, appetite, migration, and where they live. The sharks are similar in…

beach for your summertime activities. Local marine biologists who specialize in the Great Lakes and surrounding waterways recently released a startling statement regarding Lake Ontario, saying there may be a bull shark population on the rise. In late summer of 2015, scientists released roughly a dozen bull sharks into Lake Ontario in order to curb the grass carp numbers. The grass carp, an invasive species to the area, has caused many problems to fishers and the endemic species of the Great…

and oceans. And that kind of freaked me out because of bull sharks, and bull sharks can go in fresh water and I was pretty confident a shark would come bite me in the leg. But in the end a shark did not eat me, so I was okay! As I, dove down into the water the colorful reefs and fish that shined in the water, I either haven’t heard of them or heard of them but never seen them before. Cation Tape stood at the bottom of the water floor waving like crazy when the catfish bumped into it.…

DNA samples were extracted from sixteen unidentified shark tissue specimens and underwent PCR amplification of CO1 mitochondrial gene. DNA samples were assessed for presence and quality using agarose gel electrophoresis. Species identification was performed by importing finalized CO1 sequences into two DNA databases to ensure accurate identification. Phylogenic analysis was then conducted to determine relationships between identified species. Electrophoresis Electrophoresis of DNA run in 2%…

March 2018 Why Sharks Aren’t Scary Yasmine Hamdi Once said “Sharks aren't the monsters we make them out to be” Although they can be dangerous, sharks are not as scary as you think. People think that sharks are scary because of their sharp teeth, their big scary bodies, and the fact that they can attack you, but there are very reasonable explanations for each of these things, so you need not fear. The first explanation to why sharks are not scary is by explaining their teeth. Sharks have no…

Sharks Need Love Too Cold-blooded killers, heartless monsters, vicious beasts: these are a few descriptions that are used to define the most feared predator of the sea, the shark. The reputation the media has put into our heads is making a species so vital to our marine ecosystem become closer and closer to extinction when sharks are not even interested in humans in the first place. Here is a paper showing the very rarely showed, good side to sharks. Reputation is defined as: the beliefs or…

into buying or watching products they neither want nor need. According to Charles I. Brooks, author of How Psychology Applies to Everyday Life, “advertising executives try to convey a product message to viewers.” Shark week advertisement in PEOPLE Magazine is a great example of how this magazine uses psychology to capture the audience 's attention. Let’s take a look at how this magazine is effective by analyzing the image and text, the context of the advertisement, and the metaphoric context…

Anaerobic Respiration Aerobic respiration uses oxygen, and anaerobic respiration does not. Instead it has different electron acceptors. However, they both use carbon dioxide and occur in the mitochondria. Gas exchange in sharks occurs in the gills, and the gill slits found at the side of the head. Sharks have a high oxygen demand, and oxygenated water constantly has to be flowing over the gill filaments for the respiratory system to work. That’s actually why sharks have to swim while they sleep!…

Ningaloo Reef Marine Ecosystem 1. Identify ten organisms from your chosen ecosystem and draw a food web to show trophic interactions between them. Within this food web, you must include and label a decomposer. Ten organisms that live in the Ningaloo Reef include the bottlenose dolphin, loggerhead turtle, tiger shark, whale shark, Southern Calamari squid, jellyfish, zooplankton, dugong, phytoplankton and seagrass. The decomposer in this food web is bacteria, which works to further break down…
