Manta Rays
Ever since I first went Scuba Diving I have always wanted to see a manta ray up close. I have heard so many stories about them, and how awesome it was to dive with them. People have told me, "manta rays are very gentle creatures, and their size is overwhelming. They will come up to you as if you had called them like a dog, and soar gracefully over your head as you stare at them in disbelief." Right after I heard this I knew that I had to dive with, and learn everything about them. In order for me to dive with them I'm going to need to know when the best time is to see one, and where I can see one. It also couldn't hurt to know some general knowledge about them because I wouldn't want to disturb or mess up anything that is taking

First, I went to yahoo.com and typed in manta rays. Then, I clicked on manta rays, and it brought me to the site tripod.com. It was a good source of information, so I printed it out. Next, I went back to yahoo.com, and clicked on manta rays-gentle giants. This brought me to a site, which I also printed out. After that I decided to switch search engines, so I went to google.com to see if different information would come up. I again typed in manta rays and it gave me a bunch of sites to choose from. I clicked on manta rays-Cayman Islands, and printed that out as …show more content…
Unlike most fish, the female manta ray's egg is fertilized inside of her body, so their young are born like a mammal's young (McEachran). "Female ray's give birth to one or two rays per litter, each weighing up to 25 pounds at birth!" (Reef Briefs). These rays, often called pups, learn to avoid predators by staying on the bottom, and by throwing sand on their body using their pectoral fins. The only predators that they really face are the killer whale and the shark (Reef Briefs). Because of this, the species is allowed to flourish, and are able to live in many places.
Manta rays are known to be pelagic, which means that they like to live in the open ocean. Occasionally, they like to come close to the land to feed, or just to swim around. These rays, for some reason, like to spend a lot of time on the surface, or jumping completely out of the water. Some scientists' think that the reason for this is to get rid of parasites that cling to their body, or that they do it just for fun (cayman.org). People have reported that they have seen the manta rays jump 15 feet out of the water (Reef
On July 27 1959, A new York attorney named William shea had an idea of putting a new baseball team in new York since the dodgers and giants had left for california.So on march 1st 1961 His wish was granted.The new York metropolitan baseball club or “the new York mets” were introduced into the national league.The name of the team was chosen by owner Joan Payson.The other names that were put into thought were the rebels, skyliners, nybs and avengers just to name a few.On April 11,1962 the mets played their first game in franchise history and lost 11-4 to the St Louis cardinals.The first season was a miserable one.Manager Casey Stengel led the mets to a 62-100 record,The worst record in major league history.After a couple of more losing seasons, The mets finally made a move and signed pitcher Tom “the franchise”Seaver,one of the best pitchers who ever played the game. They also picked up power hitting outfielders Donn Clendenon and Tommie Agee. Finally the mets looked like a baseball team.Entering the 1969 season, my father said the mets wewr 160-1 to win the World Series, but the mets shocked everyone winning the national league championship. Now, this is how the mets won their first world series, The batter was cleon Jones, after striking out manager Gil Hodges notices a black mark on the ball. The black mark was shoe polish. Putting shoe polish on the ball makes it spin more and makes it much easier to strike out a batter.
Because of its size and abundance, T. californicus is commonly regarded as the insect of the sea. This creature is generally very small, from 1-3 mm in size as adults. They are cylindrically shaped, and have a segmented body (head, thorax, abdomen) though no noticeable division between body regions (Powlik 1966). Each segment of the body has a pair of legs. They use their 'legs' to propel themselves through the water in short rapid jerks. They have 2 pairs of long feathered antennae, a chitin us exoskeleton and a single eye in the middle of their head, this simple eye can only differentiate between light and dark.
Flying Tigers is the name of a mercenary group of American pilots that helped defend China and the Burma Road from the bombing of the Japanese during World War II. The name of their planes was Tomahawks, but the Chinese called them Fei Hu for the sharks teeth painted on their planes. Flying Tigers were known as the American Volunteer Group of the Chinese Air Force. The Flying Tigers did not see combat until December 1941 when the Japanese started bombing China.
Many people see the Atlanta Braves in different lights, by asking diverse people about them, you will get some vastly dissimilar answers. If you ask any young person who the Atlanta Braves are, you will most likely hear something like this: The best overall baseball team since I’ve been alive. But if you ask an older wiser person who the Atlanta Braves are, here’s the answer you’ll probably get: A baseball team that has come back incredibly from they’re not so grand past, a great story of a worst to first baseball team. However if you go to an informed person, someone who knows all about the Atlanta Braves and ask them the same question, I’m sure you’ll get an answer like this: The Atlanta Braves are a team with rich history, great victories, and superb leadership that has allowed them to capture 12 consecutive division titles.

Sharks have also been subjected to medical research, games and competitions, jewellery, souvenirs and cosmetics. We need to take into consideration that sharks play a vital role in the natural world that we live in. it is imperative that we look after these majestic creatures and ensure they remain protected. We need to be aware of the dangers of sharks, swim in protected areas where there are shark nets, and do not swim after dark in the sea (especially not alone) as the sea is the sharks home. Humans should also be wearing wet suits as protection in the ocean. The sea is where they live, they swim freely and they eat – they do not particularly target humans but rather prey on food that is available to them in their habitat.

My vomit clouded the ocean surface with a purple-brown color before fading below the depths. On the other side of the vessel, I re-equipped my mask and plunged into the water to be greeted by my aunt – she was to be my snorkeling partner as she had much experience in the depths of Hawaii. When I submerged my head it was almost as if I had entered a new world. This unseen dimension housed a coral reef that vibrantly shone with a mixture of bright reds and deep blues. The reef almost seemed to pulsate as thousands of fish darted in and out of their subterranean homes. The water was thick with salt and teemed with plankton. We often resurfaced to point out fish to each other. I remember my aunt telling me of the environmental dangers of touching the still-living coral. “If you pierce its skin it will likely become infected and die, and all of the fish who live in it will die too,” she expertly explained. From then on I kept my distance to at least 5-6
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.
In 2015 only 59 shark attacks have occurred around the world compared to the millions of sharks killed by humans every year. Due to these accidental shark attacks people tend to think that sharks, especially Great Whites are evil creatures with malice intentions when attacks do occur; but, on the contrary that is wrong. Sharks are not the only beautiful and unique creatures in the ocean, they also play a vital role in our ecosystem; however, due to human interference they might not be around much longer, through awareness sharks can be protected from endangerment.
The manatee is a large, bulky aquatic mammal with flippered forelimbs and a spatula-shaped tail. Manatees can grow to 12 feet in length and weigh up to 3500 pounds. They may live to be 50 years old. It might be very difficult to imagine, but manatees (also known as 'sea cows') share a common ancestor with elephants, but did not evolve from the elephant, the elephant is considered the manatee's closest living relative. The manatee's vaguely human-like face is sometimes described as one only a mother could love. Indeed, it is difficult to understand how sailors ever mistook a manatee for a beautiful
The Toronto Blue Jays baseball team was founded in the 1970s and experienced support from the fans during the 1970s and 1980s. In 1992 and 1993, the Jays won back-to-back World Series, yet in 1994, the team faced setbacks. The team had a losing streak, there was a major league baseball strike, and no World Series was played. At the same time, gambling came to Toronto, and the team had to compete for the fan's time. Also, players' salaries skyrocketed at a time when the Canadian dollar fell in value. How could the Toronto Blue Jays adjust ticket prices to improve financial performance and increase fan attendance?
They are creatures that have no clue what we are and are afraid of us. Every year, thousands of more people are killed by other people than by sharks; thousand more people are killed in car accidents than by sharks, and more people are killed by lightning strikes than by sharks. Each year humans kill tens of thousands of sharks, yet, there are fewer than 100 shark attacks upon humans. For example, The Great White shark also known as the man-eater, has the greatest reputation for attacking humans. Recent studies of Great Whites show that they mainly feed on sea-mammals. Seen from below the surface a person swimming with a shark looks much like a seal, with arms and legs sticking out. The shark usually surprises its victim, being a person or seal, by one massive bite, and then retreats in order to allow the victim to die before digesting the food. For this reason, many humans survived the attack of a Great White shark if they are saved before being eaten. Not only getting out of the water and be safe, but the result of loss, blood or
