Underneath their gill slits there are blood vessels which intake oxygen from the water; some sharks keep their mouths open to breathe so it’s easier for the water to pass over the gills. Most sharks don’t have strong neck muscles so the water doesn’t easily pass over their gills, that is why they have to keep moving with their mouths open to breathe. Some sharks, which have strong neck muscles, push the water over their gills so the shark can stay at rest and still breathe. Other sharks have tiny holes over their eyes, which the water is pulled into so the shark can breathe with its mouth closed. A sharks diet is very interesting.

Because the bull shark change its lungs and cells in order to breathe oxygen from both fresh and saltwater. The Bull shark will most often go into freshwater or a river in to breed and raise its pups, “The Bull Shark will going into Fresh water only for breeding, which includes raising its pups witch is down by the mother” (Costa rica and its changing habitat) says freshwater biologist Smith Angel.
Without sound editing this movie would not have the Hitchcock horror feel. Verna Fields did a great job blending everything together. The editor made sure through her editing style would make the shark look as authentic as possible. The best scenes in the movie take place on the boat. These are the scenes that makes Jaws great, the main characters trying their best to stay alive and kill the shark before it kills any more people.
Sea otters are omnivores as they do eat kelp and other sea-going plants. Regardless of this however, most sea otter people have an essentially flesh eating diet with sea otters known to eat more than 40 unique types of marine creatures. The sea otter chiefly chases ocean urchins, mollusks, crabs, snails and little fish in the water. The sea otter is one of only a handful couple of creatures on the planet that has the striking characteristic of utilizing devices, for example, rocks, keeping in mind the end goal to get at it 's prey. Sea otters have couple of normal predators in the ocean because of their vast size.
After the expository phase of both the movie and novel, the shark attacks its first victim--a drunk woman named Crissy. The kill set off a bloodlust instinct in the shark that made it hungry for more, and that there is more food for him at this beach; This is why it keeps coming back, because normally sharks to not attack humans unless they are in distress. Unfortunately for the Crissy, she was swimming in an unconventional way which made her appear to the shark as prey.

After the death of the guy in the pond, and near death experience of his child, Brody seems to realize that this is a pressing issue that needs to be resolved now.

Once an alligator “closes it jaw on a limb the force is so great that getting the alligator to open its mouth again is virtually impossible “ (Strawn 43 ). The adult reptile “has small legs and webbed feet that are designed for “propulsion and maneuvering but not for attack” (Visiting the Heart of Alligator Country) However the “swipe of a gators tail can knock a person into the water when it is most agile, powerful and destructful” (Strawn 43). Not to men-tion an alligators tail is what gives it it’s speed of up to approximately 20 miles per hour in water but then becomes a slower awkward giant on land. This sounds to be very similar to that of some of the dinosaurs from many years
He ends up wandering into a different species of sharks territory looking for food. He has to help them fight in a war in order to get food and a shelter. An adventurous characters, off-this-world setting and an ineffective theme make Shark Wars a book all shark lovers will pick up.

Male mature to be 2 meters maximum, females mature to be 2.6 to 4 meters long(Carson, 2015). Their average weight is 551.61 pounds to 1,102.31 pounds. The mako shark 's skin is smooth which helps the shark to swim as fast as possible. Mako sharks are very diverse in where they live. For example,
I have swum with Caribbean reef sharks in the Bahamas and have seen how beautiful and strong they truly are first hand. Sharks are a vital part to every ecosystem they are in and currently being killed at a rate that they cannot reproduce at. Alpha predators are a necessary component of eco-systems because they keep the populations of every trophic level below them in check. You can compare an eco-system to a skyscraper; you need every single part so the entire building does not fall apart. Sharks have the task of killing the wounded, old, and sick fish in schools to keep the stocks of fish healthy and plentiful.
All is quiet in the beautiful ocean then you hear a scream then you look out into the ocean and the only thing you could see was a shark tail. Older Than Dinosaurs? Sharks have lived on the earth longer than you think for example, over three hundred years ago sharks roamed in waters, that is one hundred million years before dinosaurs roamed the earth! Some of the sharks that roamed long ago don’t roam today, on the other hand a handful of the sharks that lived then still live today. Who knows there may be more sharks in the deep of the ocean that we don’t know exist, most of the ocean has not been searched.
A couple minutes later something happened that no one suspected. A couple minutes after they got to the beach, Bethany was lying on her board and she was dangling her arm in the water. Before she knew it a shark came out the water and bit her arm clean off. Bethany didn’t panic, she didn’t even scream. She called out as calm as she could and said ‘’I just got attacked by a shark!’’ Alana’s dad had gotten to her first and pushed her up to the shore.
