Cetaceans

In addition to the argument that new laws are harmful, some believe that they are completely unnecessary. Since 1988, the amount of fish caught around the globe annually has been dropping (“The Threats”). Scientists believe the sustainable amount of fish able to be taken from the ocean each year is between 110 million and 150 million tons (“Overfishing 652-654”). The current annual global catch is 90 million. The number of boats in New England waters has decreased from 1,200 to 580 since the…

They are able to accurately distinguish between different objects by making different clicking sounds and focusing the beam of the clicks they produce (Knight, 2012). Cetaceans are one of only three groups that vocalize with multiple dialects dependent on geographic location. Other groups are both bats and humans (Filatova, et al., 2012). False killer whales produce three types of sounds for communication: echolocation…

the rest of the marine ecosystem, such as the rapid growth of algae and coral reef health. Overfishing is also closely tied to bycatch, another serious marine threat that causes the needless loss of billions of fish, along with marine turtles and cetaceans. Ocean overfishing simply means catching fish from sea at rates too high where fish stocks become too depleted to recover. With oceans taking up over 70% of the Earth, ocean life and the overall survival of marine life is essential for holding…

In today’s society, school curriculums are filled with a variety of topics, from the Math’s to the Sciences, English’s to the Foreign Languages. One of the many items contained in school curriculums includes evolution. Evolution is a highly controversial subject in science that typically starts many debates with differing views on the subject. Some are for the teaching of evolution in public schools while others do not agree with evolution and does not want it taught to their children on the…

occur in tropical and subtropical Asia, Europe and North Africa, with a single genus, Rhinoclemmys, being native to Central and South America. Officially described in 1831 by John Edward Gray (1800-1875), C. dentata is one of various species of cetaceans (dolphins, porpoises and whales), reptiles and fish studied and described by the British zoologist. A prolific writer, during his tenure as the Keeper of Zoology at the British Museum (1840 to 1874), Gray produced over 1,000 papers on an array…

imitation of speech, and is therefore often used as the model to study the evolution of vocal learning and communication (Pepperberg 2010). Through studying phylogeny, it is possible that a derived characteristic may be found that explains why birds, cetaceans and elephants all possess the ability to mimic human…

George Millay, Milt Shedd, Ken Norris and David DeMott originally founded the SeaWorld we know today in the late 1950’s to early 1960’s. It was originally a subsidiary of Busch Gardens, housing a bird sanctuary, and eventually it turned into a water park. Its founders, however, had plans for the facility. They envisioned an underwater restaurant that would allow guests to look into a large pool and see marine animals close up but that idea soon expanded when Ted Griffin, sold Shamu to SeaWorld…

geographic,” “Orcas, or killer whales, are the largest of the dolphins and one of the world's most powerful predators.” Even though they are related orcas have been seen attacking dolphins (“Orca Kills Dolphin”). Both dolphins and Orcas are in the family Cetacean, which has all 76 known species of whales, dolphins, and porpoises (“WWF Global”). There is much more that can be learned about, all of this is only a small part of what you can…

At its core, altruism is when an individual behaves in a manner that benefits others at a cost to him or herself. Some believe that we as a species are inherently selfish creatures and are therefore incapable of true altruism. They say that any altruistic behavior is done in expectation of reciprocation or, at the very least, a nontangible benefit of self-satisfaction. In many, perhaps even most, cases this may be true. But this expectation of benefit from an act of altruism doesn’t hold true in…

40 years. In the US, dogs are utilized in a lot of different sections of the government. Dogs are used to “sniff” out drugs, bombs, scents from missing people, etc. War dogs are used as: patrol dogs, messenger dogs, mine dogs, casualty dogs, tunnel dogs and, sentry dogs, and more. Dogs are even used as morale boosters in military hospitals. Dogs are put in a dangerous line of work to help the military but is it humane? While these dogs do receive “top veterinary care”, they are forced to work…
