The sun hasn’t risen yet. I put my fins on my feet and swim cap on my head. Once my goggles are on it’s time to dive in. I’m plunging into the freezing ocean. Each stroke I take I'm going farther and farther into the ocean and away from the sea shore. It feels like I’ve been kicking for days, but in reality, I’ve only been in for 5 minutes. I am scared and nervous at the same time because it is my first time swimming in the cove. As we paddled out we saw colorful fish circling around us. There are red fish, orange fish, and yellow and orange striped fish swarming and following me. ”Can I actually touch a fish?” I wondered. As I reached my arm out to touch it, it zipped away. It feels like I've been in for two seconds and were already at the cove. Darkness is all around me as I am quickly …show more content…
I am seeing the seals just lying there on a hot day with my own two bulging eyes. These seals are no ordinary seals they’re huge and beefy. I was eager to go and touch their fins so I slowly swam over to them. I was thrilled to be hearing these seals barking at my dad and me. It feels like I’ve been looking at them for ten seconds, but actually, it’s just been a split second. I don’t know why I am slowly moving away because I like the seals and I wanted to swim around their cave a little longer. While I am swimming farther away from the cave I see a gray shape in front of me. I also see that it has an arch on its back. At first, I was frightened that it was a shark but I was relieved it was smaller than a shark. I saw it dive under for just one second because it was really speedy. This was a very chunky, gigantic shape, thankfully it was just a dolphin. I can see that people are trying to talk to me, but I can’t understand anything because my ears are in the water. After my adventure, it is time to head back in. On my swim back in I saw more colorful
If you think you've seen one dolphin swim you've seen them all, Jason found one that promised to be different. He headed 5km off-shore to where the dolphins take you right into their world as you swim with the pod, the only place in New South Wales you can do that.
This image is what a majority of people believe to be the shark. They believe it to be the bloodthirsty sea monster that appears in countless works of literature and films, but science says otherwise. The classic picture painted by the minds of sailors returning from years at sea come from imagination and sharks’ violent methods of hunting and mating. Sharks fear humans as much as humans fear sharks, and most sharks, particularly the “man-eating” great whites, only bite humans because they mistake surfers for seals. In earlier times, the ocean was a source of mystery and adventur...
Image sitting on the beach one July morning. The sun is beaming down and decide to go for a swim. As you approach the water, you see a whale unusually close. You begin to get nervous as it continues to approach the shore. However, you aren’t worried because you know that they are confined to the sea. As the whale comes near you can see it clearly. Just as you think that it will turn around, the whale walks out of the ocean!
Harbor seals are marine mammals that have spotted coats in a variety of shades from silver gray, black to dark brown. They reach 5 to 6 feet in length and weigh up to 300 pounds. Harbor seals are dimorphic, with the male being slightly larger than the female. They are true, or crawling seals, which means they have no external earflaps. True seals also have small flippers, and move on land by flopping along on their bellies. They breathe at the surface and hold their breath while diving. They can dive to 1,500 feet for up to 40 minutes, although their average dive lasts 3 to 7 minutes. Their scientific name basically means 'sea calf' or 'sea dog.' This nickname is fits them well, as these seals closely resemble a dog when their head is viewed at the surface of the water.
looked at from the grandest scale, it is possible to see the whale and the
The Harp Seal lives in the chilly waters of the North Atlantic and Artic oceans. They spend majority of their time swimming, but do go on land. The Harp Seal eats approximately sixty-seven species of fish and seventy species of invertebrates. These animals are prey of Polar Bears, Killer Whales, and Greenland Sharks (Kovacs, 2015). The Harp Seal’s status is least concerned. They move to Newfoundland, the Greenland Sea, and the White Sea for breeding. As a result of climate change and overfishing, it is predicted that Harp Seal populations will decrease because of loss of pup raising space and loss of food supply. National Geographic. (2016)
We started to touch them and the starfish had such a unique texture. Afterwards, we washed our hands and headed outside and joined a line that was heading into a big, blue tent. We went inside and we were both surprised and excited to see tons of different-looking and sized stingrays swimming graciously throughout the pool. Everybody leaned over and reached their hand in the water, hoping that their hand would touch a back of a stingray. At first, I was scared to put my hand in the water because I didn’t want to accidentally touch the tail of the stingray even though they removed the barbs so they couldn’t sting you. Kristen didn’t have any trouble touching them, but for me on the other hand, it took a little longer. Kristen really wanted me to touch one so she grabbed my hand and slowly put it into the water. Having my sister there with me made me feel a lot less scared. We saw a small stingray heading our way, so Kristen lowered my hand and then my hand touched the back of the stingray. I was surprised of how smooth it was. It was as smooth as a fleece blanket. I was really happy at the end that Kristen encouraged me to touch one. After that I was able to touch a few more, except there was a big black covered sting ray with white spots that was probably five times bigger than the rest of them, that I was scared to touch and so was Kristen. We exited the tent and got our picture taken with the view of the city and Lake Michigan.
...we found the bodies, yet the crashing blue-green water spins me into a reality that is worlds away from the sight of stiff men. I'm not sure if this is healing or forgetfulness; all I can be certain of is the bite of the water on my skin and the dropping sun. I stare at my hand under the surface of the water, fascinated by how far away it looks and by the deep blue color of my fingernails. That hand isn't a part of my body, how can it be, it is deep in the water, opening and closing experimentally as water crashes on top of it. I want to leave it there, forever feeling the numbing water, forever fighting the currents that would wash it out to the Pacific Ocean. But then my arm moves, lifts my hand, and I realize it is mine, as are my legs and toes and wet matted hair. And the water keeps falling, pounding, rushing and I just stand there, staring, watching, waiting.
Even though many people spotted the giant creature in the Ocean no one believed it was real because there was no physical evidence but their was sightings. Olivier de Kersauson was trying to break the record of sailing around the world “...when his boat came to a mysterious halt” (Hanna 11). They began trying to see into the water with flashlighting trying to figure out what was happening. Then a crew member that was under deck looked through a
very sickle shaped dorsal fin. Even though the blue whale is large and seems easy to document,
Kristi and I were given the key to our room. OUR room. Thank god our parents had decided to get a third room just for us. Unfortunately, it was in a middle hallway, which meant no windows. But on a boat like this, who needed windows?? We got to the door, Level 3--Room 3053, and our bags were sitting neatly outside the doorway. One swipe of the card key in the door and we threw the bags in. Time to explore the rest of the surroundings.
Another goldfish with a long, beautiful orange tail swims by me. This elegant goldfish looks exactly like me except I am about an inch bigger. As this fish passes me, two other small gold fish swim about in search for food. One of the two has a huge white spot on the side of its body and its orange flat tail. The other is plain orange with a wide tail. Right now the white spotted goldfish is motionless. The water is so clear, it almost seems like he's floating in air. I almost hit him as I swim down to consume some more fish food.
These dolphins are the type of dolphins common people would see at the Zoo or on a T.V. programed performance. Like the Common Dolphins, the Atlantic Bottle-Nosed Dolphins are highly skillful echolocators. They can produce a range of sounds, like a click, using it to analyze any object around them in the ocean (Whitfield 114). According to Whitfield on page 114, they can produce up to 100 clicks a second. They will use these clicks to also find food. They mainly eat Bottom-dwelling fish in inshore waters or surface swimming fish. They can do many other objects with their echolocation finder and using their
I will never forget the first time I went snorkeling, it was something I had been afraid to do up until the moment I touched the water. Beforehand all I could think about was what if I got attacked by a shark? I was too young to die and I felt like I was tempting fate. Then once I made the plunge into the water everything washed away, as if the waves carried the fear with them as they folded over me. I remember that day so clearly, rocking back and forth, up and down, I sat on a small glass bottom boat. The enormous ocean waves making me nauseas as I put my snorkel gear on. I hurried as fast as I could, knowing my nausea would go away as soon as I entered the water. This wasn’t the first time I have gotten sea sick, but it only shows up when the boat is sitting still. As soon as I got my equipment on I jumped into the water, fins first. I felt the sensation of goose bumps shivering up my whole body, tiny bubbles rolling over my body from breaking the surface, they ran from my toes upwards to break free at the ocean’s surface. Once the bubbles cleared, I looked around to see a new blue world I have never experienced before. I heard the sound of the ocean, mumbled by the sound of my deep breathing and the tanks of the more experienced scuba divers below me. It’s a very relaxing and peaceful sound, and if I had not been in such a new and unusual place I could have floated with my eyes closed for hours.
The lorenzini is a pit-like organ located on the head of the whale shark that senses weak electrical and magnetic fields. This is an area that is currently being researched extensively and is largely unknown. It is speculated that this organ is used by the whale shark as a navigational aid by using the earth’s magnetic force (Rowat 2012). Evolution Studying the evolutionary history and adaption for this species is difficult and an ongoing struggle for scientists. It is classified in the order of Chondrichthyes, suborder Elasmobranchii, and family Rhincodontidea.
