Bottlenose Dolphins This essay is NOT formatted Bottlenose dolphins are among the most vocal of the nonhuman animals and exhibit remarkable development of the sound production and auditory mechanisms. This can be seen in audition, which is shown in the animal’s highly refined echolocation ability, and in tightly organized schools in which they live that are made up by sound communication. In testing the communication skills of dolphins, extensive studies have been done on vocal mimicry, in which the animal imitates computer-generated sounds in order to test motor control in terms of cognitive ability. Language comprehension on the other hand has been tested through labeling of objects, which has proven to be …show more content…
1986). In order to understand the complexity of these highly mechanized acoustic systems, it is necessary to learn the process for which the dolphin hears. In most water-adapted cetaceans, tissue conduction is the primary route of sound conduction to the middle ear. The isolation of the bullae shows an adaptation for tissue conducted sound. The lower jaw contains fat that is closely associated with the impedance of seawater. The lower jawbone of most odontocetes becomes broadened and quite thin posteriorly, and the fat forms an oval shape that closely corresponds to the area of minimum thickness of the jaw. This fat body leads directly to the bulla, producing a sound path to the ear structures located deep within the head. Paired and single air sacs are scattered throughout the skull, which serve to channel these tissue-conducted sounds (Popov & Supin, 1991). Other than this description, there are still more studies needed to determine the function of the middle ear and the type of bone conduction that occurs within the bulla. Due to detailed audiograms, dolphins have been shown to have the ability to detect high-frequency sounds. In an experiment by Johnson (1966) as cited in Schusterman et al. (1986), sine-wave sounds ranging in frequency from 75 Hz to 150 Hz were presented to a bottle-nosed dolphin. The animal was trained to swim in a stationary area within a stall and to
There are five teams that are worthy of being called the greatest team in NFL history: the 1972 Miami Dolphins, the 1978 Pittsburgh Steelers, the 1984 San Francisco 49’ers, the 2007 Patriots, however the 1985 Chicago Bears stand out amongst the crowd because of their outrageous defense, popularity amongst the NFL fans, and their roster that was filled with Hall of Fame talent. According to the 1985 Chicago Bears Statistics & Players (2017), the team finished with a season record of 15-1. News analyst Tony Andracki (2016) stated that, “The 1985 Bears turned in one of the most dominant seasons in American Sports” (p.1).
Have you ever experienced the death of a beloved pet? If you have, I’m sure it was hard to get through, being so attached. For David Barry, his view is different - experiencing this can be an important lesson for kids. In many other disappointing circumstances, there’s always that one person who attempts - and sometimes succeeds - at being cheery through it. Similar to this type of person, Barry’s writing sheds light on the loss of a pet being an important lesson through humor that may improve the reader’s attitude towards their own loss. David Barry’s short story “I’ve Got A Few Peeves About Sea Creatures” is a high-level comedy that uses sarcasm and various types of comic language to convey the idea that the occurrence of losing a pet can be a teachable experience for a young owner if taken light-heartedly, with an open mind.

Arising over 350 million years ago, the shark species has been labeled as a human devourer. Now, with the increase in human population, the demand for shark meat, fins, and cartilage are at an all time high; therefore, the existence of the shark is becoming a concern (Budker 1971). Individuals are conditioned to think of sharks as a negative aspect to the environment, which is prolonging the effort to save shark species from becoming extinct. With that in mind, some private as well as national organizations have accepted the challenge of educating and informing people about the existence of the shark specie and its importance to the sea.

If you have ever been to Seaworld you would have had to go see the Killer whales in fact its one of the top attractions there. Through the eyes of a child, these gentle giants seem to be happy, healthy, and enjoying a playful game with their trainers. The question is are they really happy, do they get treated the right way, and why have there been deaths and injuries. Many people wonder about these things and after the movie Blackfish came out more and more people began to question how well Seaworld treats their animals. “The truth is that Sea World keeps its animals for entertainment and money and helps no one but themselves.”- Animal Legal Defense Fund
Killer whales are one of the most fascinating displays of ocean life. The killer whale has characteristics that are important to its survival in the ocean. It is interesting to know that killer whales have a plentiful diet. It is astounding to see how killer whales behave in the ocean. I plan to tell you about the killer whale, its characteristics, its diet, and its behavior in the ocean as well as the predation of the orca.
There is something about dolphins that fascinates me. They are some of the most intelligent and beautiful animals that I have ever seen. Their faces are so cute that every time I look at a dolphin it looks like it is smiling at me and wants to tell me something. The noises they make represent some kind of language and it makes me wonder if they can really communicate. I also want to know what kind of feeling they have and whether they have emotions. This is why I chose to do this I-search project on dolphins; the different kinds of dolphins there are, the places that they can be found and their mental abilities.
There are so many interesting things about them. Dolphins have been around for about 15 million years now. They’re extremely intelligent, probably even more intelligent than us humans. Dolphins are becoming endangered because of humans and many don't know that. They are known as the oceans most kind animals.Dolphins have originated millions of years ago,are extremely endangered,and are becoming endangered.The most important thing to know about dolphins would probably be how they originated because without that those cute aquatic mammals wouldn't even exist.
Whaling has become a global environmental issue as vast numbers of whales are killed commercially and scientifically every year. Intense debate on the necessity of whaling has been stirred but failed to be resolved due to the lacking of pragmatic measures employed by the responsible parties. Whaling nations continue to defend their whaling right for cultural and research purposes. Yet, ethical and humanity issues are among the controversial disputes raised by concerned public. In February 2010, International Whaling Commission (IWC) proposed a plan of lifting whaling ban by limiting scientific whaling activities with the intention of reducing overall number of whales killed besides solving the current impasse between pro
Sharks are one of the most feared carnivores in the sea. There are 365 species of of sharks in the sea as we know today. All sharks are carnivores. Most of them eat live fish, including other sharks. A shark's most common natural enemy is an another shark. Most sharks eat their prey whole, or they tear off large chunks of the bodies. Some sharks crush their prey. Others take out small pieces off flesh from large fish. Sharks also feed on dead or dying animals. Sharks have the reputation of attacking human beings. But less than 100 shark attacks a year are reported throughout the world. Sharks are most common in warm seas and oceans. Whale sharks, are the largest shark known to man. Sharks are classified in the order
Commercial whaling is a serious world issue that has always been difficult for those who are in support and those who are against it. Each group defends their side with convincing arguments. Morally, whaling is wrong, but do the reasons for whaling outweigh the reasons to cease the primitive hunts? By studying the effects of whaling,realizing how culture has changed over time, and taking note of the money that would be saved, it can clearly be seen that there is no longer a current need for whaling to continue. Efforts have been made to try to stop whaling, but with no help from any authoritative figure,nothing has been done to regulate the whaling. The famous sea shepherd, known for its strikes against whaling, can even be seen on
“Splish! Splash!” The sound of bottlenose dolphins jumping and swimming around their tank excites a family at SeaWorld as they wait to experience their first encounter with the dolphins. Every year, bottlenose dolphins bring joy to hundreds of people in both captivity and the wild, but what do people truly know about them? Bottlenose dolphins are actually unique and interesting creatures.
However, many fisherman are unable to catch as many fish as they used to, so they are increasingly using cyanide and dynamite in fishing, which further degrades the coral reef ecosystem.[6] This perpetuation of bad habits simply leads to the further decline of coral reefs and therefore perpetuating the problem. One solution to stopping this cycle is to educate the local community about why conservation of marine spaces that include coral reefs is important.[7] Once the local communities understand the personal stakes at risk then they will actually fight to preserve the reefs. Conserving coral reefs has many economic, social, and ecological benefits, not only for the people who live on these islands, but for people throughout the world as well.
It was dark outside. Clouds loomed over the skies as I walked into the enormous colorful building. Blazing rays of LED lights shone through the entrance’s translucent windows. Brightness and gleams engulfed my vision like a wildfire. My eyes blink, trying to focus where I was walking. As I paced myself through the crowded corridors of the large hallway trying to find my group of friends, I could see murals of sea animals everywhere and signs directing where each exhibit was. Animated and overjoyed, I pranced to the first exhibit where the baby sand sharks were. They were extraordinary, swimming around their tank but sadly not able to leave their confined space. Their tank only allowed them to swim continuously in circles. Although animals in captivity tend to live longer than animals in the wild, it is depressing to mull over how they were stripped of their freedom. There was nowhere to escape when housed in such small enclosures.
