Whales may become endangered as a consequence of the lack of communication caused by human activities. Because the natural noise wasn't enough humans have decided to ruin the ability of whales to communicate by their egocentric activities, for instance, more wind farms, which didn't only make a continues low-frequency noise, but also denatured the whales by making them either make a much louder sound or by communicating with higher frequencies, depleting their energy on such a simple activity as communication. However, scientists have managed to attach a recording device to record the whales' calls as well as the background noises; ironically the devices and ships used for the analysis made the loudest noise that these whales…
In the year 1828 the first whale shark was discovered by scientists. Whale sharks are the largest fish in the sea, measuring lengths of up to 40 feet long. That is about the size of a bus. Even though the largest whale shark in the world was 40 feet long scientists think that the species could grow even larger than that. Whale sharks are carnivores so t hey eat meat.…
I believe that underwater noise has an affect on marine animals such as whales. Using information from the passage I will prove my point. In the first passage titled "What to Do about Underwater Noise" it is stated, "It interfered with their communications and caused them to change their diving and feeding patterns." Since whales interact by sending sound waves to one another the intensity of underwater noise has interfered with the whales ability to hear each other.…
Abstract: Human impact has lead Eubalaena glacialis, or the North Atlantic Right Whale, population to be classified as critically endangered. Habitat fragmentation, fishing entanglement, whaling, and shipping are of the main direct human impacts that have affected the North Atlantic Right Whale population. This leads to a decrease in population because of mortality, injury, or other health impacts. Despite conservation efforts the North Atlantic Right Whale population has not seen much growth with estimates of 450 to 500 individuals left in the world’s oceans. Results from multiple studies have shown that the need for continued species conservation efforts are necessary.…
It is required to conserve a certain population-level of every specie in order to prevent biodiversity loss and for ecosystems to continue operating. Whales are starting to extinct and whaling is one of the important causes of this problem. The blue whale is the largest animal and a lot of them are found in the Antarctic. The specie reduced abundantly because of hunting in the 20th century. The Antarctic blue whale is classified as Critically Endangered on the International Union for Conservation of Nature (IUCN)…
In this study I want to tag Biggs killer whales (Orcinus orca), also known as mammal eating or transient killer whales, in the mid-Salish sea. Biggs killer whales are named after Michael Bigg, a Canadian marine biologist who is considered the founder of killer whale research (Paterson, 2002). Bigg was the first scientist to look at the differences between killer whales that preyed on fish and stayed in one home range all year and those that preyed on mammals and live in larger unknown ranges. It is believed these two ecotypes diverged roughly 700,000 years ago which helps explain the differences in life history strategies (Hildering, 2013). Biggs would go on to discover the distinct cultures that exist in killer whales as well as how to identify…
The world is a bustling and noisy place, and now so is underwater. With drilling and marine sonar testing, it is no wonder whales can't live in peace and quiet. So it is our job to bring a halt to all the noise and allow these beautiful creatures to live in peace! I think that the underwater noise does in fact, affect the live of whales and many sea creatures. One reason I do believe that these noises are affecting whales is because scientist conducted an experiment over a two year span, and found out that the these sonar testings are interrupting the communication between whales.…
Blue Whales, the largest animals in the world so far, are facing with the situation of being extinct, as they have been harvested for a long time, making the population decrease to 50,000. In the early 20 century, people took up whaling for the energy sources, and the meat and fat of whales can be used in different ways. Since the price of whale meat is really high, many people regard the profit as the chief motivation, caring less about the ecological system. There were about 66000 whales being killed during a hunting season in 1961 and till the International Whaling Commission (IWC) banned whaling, the number of whales has decreased 99% of it’s total population.…
The blue whale is a marine mammal. It is the biggest living creature in world. Their veins are so big that a human could swim in them! The heart of a blue is as big as a slug bug! They are not fish because they breathe air and they give birth.…
The North Atlantic whale’s population is declining at an alarming rate. Scientists fear the population might go extinct in mere years. Experts believe that the government must act fast to save the population. The major threat to the whale population is entanglement in fishing gear. Over 85 % of whales have been caught up with fishing gear at least once.…
Scientists have found out that blue whales are a little bit ambidextrous. When deep water hunting, the whales appear to be “right-handed” because they lunge to the right at krill, twisting about 180 degrees. But when hunting close to the surface, the whales will do a complete barrel roll to the left to feed on the tiny crustaceans close to the surface. Scientists say rolling to the left near the surface may help the whales to see their food better.…
The Whale is a large, magnificent, intelligent and aquatic mammal. They breath from a hole on top of their head called a blowhole, into their lungs. The whale has a very smooth skin that covers their very streamlined body that moves easily through the water. They are the only mammal that has adapted to life in the open oceans.…
It appears like Japan does not really care about the global ban on whales. It has been reported that Japan will continue their hunting of whales after a 365 day drought. Japan seems convinced about the idea that whales don't deserve to live. It has been announced that Japan will only do it, however, on a limited level and it will not be a full on whale killing spree.…
