If a van cannot be availed of, jeepneys plying the Dumaguete-Bais route cost only a cheap P15, and another P10 to take you to the Capiñahan Wharf. Dolphin and Whale Watching in Bais City Dolphin and Whale Watching is fast becoming a national attraction as well. It has gained popularity among travelers both local and foreign because of its appealingcombination of activities. The adventure starts with a cruise along Bais Bay then out to Tañon Strait, the natural habitat of several whale and dolphin specie. Among the kinds of dolphins you may encounter during the trip are , pantropical spotted dolphins, bottlenose dolphins and long snouted spinner dolphins. Melon headed whales, short finned pilot whales, pygmy sperm whales, pygmy killer whales and dwarf sperm whales are commonly found in the Tañon Strait too. After the show of sea mammals, you head out to Manjuyod White Sand Bar where the boat temporarily docks. Here you can savor your lunch of grilled pork and fish while looking out into the blue sea and sky and the white sands of Manjuyod.

...part of nature and should not be bought, sold or thrown in an aquarium. I believe that they have the right to be kept in their natural environment. There are many convincing reasons to support this opinion. Captivity causes many health problems in marine mammals. Many tanks have water full of chemicals and bacteria; these results in blindness and many skin problems in dolphins and other marine mammals. Marine mammals in captivity die from pneumonia, ulcers and other stress related diseases. Most of these helpless creatures suffer from boredom. Dolphins in the wild can swim from 40-100 miles per day but in pools they go around swimming in repetitive patterns. Due to boredom and limited space many dolphins abuse themselves; they often bang their heads against tank and aquarium walls. Some of these poor innocent creatures face abusive treatment by their caretakers, thus shortening their lifespan. In fact Keiko, the killer whale, the star of Free Willy, was a victim of this type of abuse. Marine mammals breed very poorly in captivity with very high infant death rates. For this reason, when a baby dolphin is born into captivity its birth is usually kept a secret from its mother until it shows signs of survival. Marine mammals do breed in captivity, but the birth rate in captivity is not as successful as in the wild. Many people think that marine mammals should remain in captivity. I realize that some people may believe that captivity increases the life span of certain animals...

...visitors who watch dolphins, beluga whales, and orcas perform their majestic tricks; they’re amazing, stunning, and very “enjoyable”… However, it might only seem fun to you, the marine animals who are performing the tricks themselves have to disagree, but, the question is, do you know the truth behind all this “joyful fun”? Marine animals in captivity is wrong. It needs to stop if it only means pain and abuse for our entertainments’ sake. I have many convincing reasons to support my opinion, including how captivity causes many health problems in marine mammals, these helpless creatures suffer from boredom, most of these poor innocent creatures face abusive treatment by their caretakers, thus shortening their life span by quite a lot, and marine mammals breed very poorly in captivity with very high infant death rates. So keep an open mind and choose to spend your money on family activities this summer that do not contribute to animal suffering. For starters, many wonder first where they all come from, or more importantly how they capture them. Dolphins are sometimes purposely injured by the capture teams to force the rest of their pod to stay behind into the trap, due to that dolphins never leave behind sick or injured friends or family members. But most times, capture teams on their boats bang long metal rods against another to scare a pod to shallow waters. Nets are raised at the end of the shallow waters to prevent any from escaping, and nets are dropped over dolphins as they panic...

...Dolphin notes Wikipedia (various) They have well-developed hearing − their hearing, which is adapted for both air and water, is so well developed that some can survive even if they are blind Dolphins feed largely on fish and squid, but a few, like the killer whale, feed on large mammals, like seals. Male dolphins typically mate with multiple females every year, but females only mate every two to three years. Calves are typically born in the spring and summer months and females bear all the responsibility for raising them. Mothers of some species fast and nurse their young for a relatively long period of time. Dolphins produce a variety of vocalizations, usually in the form of clicks and whistles. Dolphins are descendants of land-dwelling mammals of the artiodactyl order (even-toed ungulates) J.G. Williams The primitive cetaceans, or archaeocetes, first took to the sea approximately 49 million years ago and became fully aquatic by 5–10 million years later.[22] WIKIPEDIA channeled vibrations from the jaw to the earbone which occurred with Ambulocetus 49 million years ago, a streamlining of the body and the growth of flukes on the tail which occurred around 43 million years ago with Protocetus, the migration of the nasal openings toward the top of the cranium and the modification of the forelimbs into flippers which occurred with Basilosaurus 35 million years ago, and the shrinking and eventual disappearance...

...Bottlenose dolphins are generally found in the world’s temperate and tropical waters. Some populations can also be found in bays, estuaries, river mouths, coastal waters as well as offshore waters. They are found primarily coastal but also found throughout all oceans, however, temperature seems to limit the range at where they are found either directly or indirectly through distribution of prey (Wells and Scott 1999). Majority of the bottlenose dolphins are found living near harbors and estuaries and has a worldwide distribution that ranges from 45°N to 45°S. They usually travel in groups and live all around the Black, Mediterranean and Baltic seas as well as the Atlantic, Pacific, and Indian oceans. There are two subspecies of the bottlenose dolphin,...

...Working as a whale trainer at SeaWorld has become a dream job for almost any child who has witnessed the wonder of Shamu. The History of career field People have been training animals for thousands of years. Historically, falconers have trained hawks. Dogs have been trained for hunting, for herding livestock, and for pulling sleds. Elephants have been trained to pull or carry logs. Horses and camels have been trained for riding and hauling. Compared to other types of animal training, marine mammal training is a relatively new field. People have been training killer whales for only about the past 35 years. SeaWorld animal trainers began working with bottlenose dolphins in 1963 before the first park opened. Requirements Each year, hundreds of men and women apply for positions in SeaWorld's and Busch Gardens' Animal Training departments. The number of openings is generally limited to fewer than 10 hires per park each year. For SeaWorld, a college degree is not required to be eligible for an animal training position, but it is preferred. Applicants are expected to complete some college coursework in biology, marine biology, zoology, and animal behavior or psychology. Colorado Mountain College, Quinnipiac College, and University of Florida are among many listed and recommended by SeaWorld that offer Zoo research and management programs. Prior experience with large animals is preferred. Experience working with horses or birds, working on a farm, or volunteering at an...

...The U.S. Navy has been working to advance its ability to detect enemy submarines for decades. The Navy’s low-frequency sonar system has been a topic of controversy among environmental advocates for years. This system, known as Surveillance Towed Array Sensor System Low Frequency Active (SURTASS LAF) allows the Navy to detect enemy submarines with enough time to react and defend themselves. During the course of developing and testing the SURTASS LFA system, environmental interest groups raised concerns that the system may cause harm to marine mammals. Whales use sound for communication, navigation, orientation, and in locating food. This is known as echolocation. The Navy’s mid-frequency sonar can cause whales to dive deeper into the ocean, or rise quickly. Like humans, whales can get the bends from these types of underwater movements. The loud noises created by the Navy’s sonar system are believed to interrupt their ability to communicate, navigate and look for food. These disruptions are believed to harm the whales physically and cause state of panic which often leads to strandings and collisions (Drumm). Active sonar utilizes sound in order to find objects in the water. A pulse is sent through the water, and then reflects off an object. This is called an echo. The receiver will convert the echoes into electrical signals which are digitally displayed on board the vessel. The high tech computers will be able to extract information such as distance and direction of the object...

...DOES MILITARY SONAR KILL WHALES? In this report I’m going to argue against the concerns that a dolphin and whales conservation group have produced, and I will support my argument with evidences to prove my choice. I’m also going to use couple of charts and data to back up my answers. A dolphin and whales conservation group have produced artificial report. For instance they wrote ‘whenever there is a military sonar exercises, up to 200 whales die as a result of sonar damage’, which was exaggerated, 200 whales and dolphins died just once and that was on Manila Bay, Philippines in 2009. When we look at the data we can see the average number of cetacean stranded is 28.2, and ranges from 1-200 The reason I put the second graph is because it said on my sheet to plot a bar chart of the number of deaths at the time of naval exercises on the axes (3. 1) – hope it makes sense The secondary source from table one has a limited analysis; they have missed out so many years such as 2001, 2007 and they doubled up the year 2008, and it is in various locations. The second statement ‘Whales and dolphins are being damaged all around the world by military sonar exercises’ needs to be shown by having more locations that show that places with no sonar activity have no stranding. They have not told us how many military sonar exercises there were in one year or how many stranding there are when there are no military sonar exercises. They have also not told us how big the sonar exercises were so...

...Dolphins Belong to the Wild-- Captivity Harms Them The essay “Orca Encounters” discusses how much humans can help the orcas when they are separated from their family and arrive at our coasts. Should we send them back their pods, or just let them interact with humans? In the text, some experts believe it’s better to let the orcas stay, because the social interaction that the orcas are seeking can be made up by humans, so they may not be interested in returning back. Many other experts believe that the solitary orcas belong to their family, and it’s improper to keep them from returning. Also, the text mentions more scientists agree that “any reunion of wayward cetacean with its pod should happen quickly”(Groc 162). However, there isn’t an example of other cetaceans, and the text doesn’t give any detailed information about what scientists have studied to reach the agreement above. For instance, solitary dolphins are even more common to see than solitary orcas, and many of them have been captured because their kindness and cleverness make people keep them, even though many studies show captivity does harm to the dolphins. Fitness of the dolphins is influenced the most during captivity. As the environment has changed after being captured, dolphins’ emotions have also changed. “[The captivity of dolphins] causes desperation because their basic instincts are obstructed, obviating millions of years of ingrained behavior”(Rivera). Rivera states that mother dolphins take care of...

...Brandon Farrow Mrs. Cox English 1 11/11/13 Navy Dolphins Dolphins are smart and amazing creatures. Scientists say they might almost be smarter than humans; they adapt really quick to their environment. The Navy is one branch of the United States armed forces that conducts military operations at sea. The Navy has programs with animals to help them protect the nation. The Navy and dolphins work together to control warfare in the water by using their sonar to track underwater mines and to keep citizens safe. These next paragraphs will explain how the dolphins and navy work together. One of the first dolphins used by the Navy was Tuffy. “Tuf Goy [Tuffy] joined the marine mammal program at Point Mugu in May 1964. By the end of September of 1964, Tuffy was retrieving a ring from the bottom of the lagoon at a depth of 200 feet” (Wood, 1973). In July of 1965, Tuffy was asked to participate in the Sealab II project with his main job being to help with the rescuing of a lost diver. Tuffy had a secondary job also of “carrying small objects-tools, for example-from the surface down to aquanauts working outside the habitat.” (Wood, 1973) “Tuffy repeatedly dove 200 feet to the Sea Lab II installation, carrying mail and tools to navy personal. To prepare for underwater tasks, Tuffy trained for six weeks and “learned to respond to a noise buzzer for the tests” (Presnall, 2002,) Judith Presnall’s book Navy Dolphins (2002), gives a visual image of Tuffy in training for rescuing lost...

...evolved as a result of environmental changes within their habitats. To understand better this paper will examine a diagram of a dolphin and give details about how the dolphin has evolved physiologically and has become adapted to fit the environment. Dolphin Characteristics Dolphins inhabit all oceans and the seven seas; some also inhabit larger river systems. Dolphins are extremely social organism and use communication for the function of hunting, defense, and reproduction. In general a dolphins live pods of up to a dozen individuals. Dolphin pods can emerge temporally forming a superpod the emerging pods may exceed thousands of dolphins. Attachments in pods are not set; interchange is regular. On the other hand, dolphins can generate great social bonds; they will remain with wounded or individuals in poor health, even assisting other dolphins to breathe by bringing them to the surface if required. Dolphins are carnivores their diet consists of fish, squid, octopus, cuttlefish, crabs, shrimps, and lobsters. Dolphins are a food source for sharks, and killer whales. The most dangerous predator for the dolphin is humankind. Man slaughters dolphins for their meat, fat, and for being in the same location where they fish. There studies at this time being done to evaluate the influence of pollution in the water and the effects on dolphins. Dolphins give birth to live young, and the mother nurses the calf with her milk and provides care. The calf is nursed by the mother for...
