The trichechus most commonly known as the manatee is a large aquatic mammal with ancestors dating back to 45 million years. The modern manatee has been found in fossil evidence to have existed for at least 1 million years. Living in shallow bodies of fresh and saltwater the manatee is mostly a gentle solitary animal, with highly developed social skills. While different variations of the manatee live across the world, all manatees are slow moving herbivores with very few natural predators. While the manatees are rather slow animals they are agile and can easily maneuver underwater. Closely related to the elephant, the ancestors of the manatee were once land animals, but with time developed into gentle aquatic mammals occupying regions such as Florida, the Amazon River, and parts of the West African coast. The manatee is a truly
The population of the largest and most significant vertebrate plants feeds, including sea turtles, dugongs, have been severely decimated by the impacts of humans on the reef. The loss of these vital animals has and will more severely disturb the coral reef food web in a significant manner, although the specific impacts are not clear
The same thing happened in 2002 where thirty four endangered manatees died in Florida and again in 2004 when 107 bottlenose dolphins died off the Florida panhandle. “In the spring of 2002, 34 endangered Florida manatees (Trichechus manatus latirostris) died in southwest Florida, and 107 bottlenose dolphins (Tursiops truncatus) died in waters off the Florida panhandle in the spring of 2004. In both of these unusual mortality events, extensive water surveys revealed that only low concentrations of K. Brevis were present” (Flewelling, L. J., et al 755). Later on in that article it states that after extensive tests high amounts of breve toxins were found in both the dolphins and manatees systems which concludes that they were exposed and it was the
Manatees are threatened by various human activities such as boats and fishing. According to statistics, manatees faced countless number of boat collisions all year round. Because of these collisions, some of the manatees have scars on their bodies and sometimes lead to death. Researchers were speculating if manatees respond to the boats that were coming towards them. To come up with a solution to prevent the increasing number of collisions, researchers have conducted a case study in which they see whether or not if the manatees respond to vessels.
Water pollution has the potential to kill many species of fish and marine life, disrupting the ecosystem. Along with pollution, fishing, boating, and diving can cause damage and disrupt the natural order. While tourism is wonderful, some of the activities associated with tourism can severely damage the coral and the marine life. This is why the Florida Keys National Marine Sanctuary is such an important part of keeping the Keys a great place for marine life to thrive. This sanctuary provides protection for many species and ecosystems and helps to keep the Keys safe from its greatest danger: man.
There are droughts, floods, acidifying oceans, dissolving coral reefs, and faltering plankton stocks caused by those things (745). All of these things can and will cause a devastating crisis in the world. The past, present, and the future have and will be exposed and affected by all of those things. Some of the insects we need now to take care of this earth and to help the animal and human population survive, may not be here in the future. The animals are getting affected by the environmental
Andy Dehart, Discovery Channel Shark Advisor, spoke about the North Carolina shark over fishing problem. The shark populations on the East Coast were extremely over-fished which lead to the over population of sting rays, a main food-stock for sharks. The stingrays in turn decimated the shellfish populations on the East Coast, leading to calm and shellfish shortages. This shows that sharks are necessary for every eco-system and their destruction affects us in more ways then we can imagine. Sharks are very at-risk for over-fishing because they take a long time to reach the stage where they can reproduce and in general only have a few pups when they give birth.
Harmful fishing methods are unnecessarily killing turtles, dolphins, and destroying critical habitats. Global warming is increasing the temperature of the ocean water, reducing the generation of the base of the food web, plankton. The reducing of the plankton generation is causing major marine ecosystem change. Pollution is also a significant environmental issue HAL is facing. More oil reaches the ocean each year, a massive amount of oil has been accidently spilled from ships, which in turn is destroying animal and aquatic plant life.
The monk seals are a rare tropical animal that lives on the Caribbean and the Hawaiian Islands. Monk seals live in warm waters and spend about two-thirds of their time at sea. However, they also spend time on land as they breed and carry-out their “pups.” Coral reefs provide the seal as a great habitat for them to dive, swim, and for food such as fish. It may seem that monk seals spend most of their time at sea, but they also love to rest on shore on the beaches. From resting and birthing to nursing newborn seals, the seals try their best to survive. Why are these animals extinct, then?
While researching about how pollution affects sea turtles, we faced some issues on finding different types of pollution. As most people know, the plastic waste that is being dumped into the oceans and onto the beaches is becoming a main food source for sea turtles. When sea turtles see this trash, they consume the plastic causing death or severe sickness which has caused this species to become endangered. They also get tangled with the plastic in the ocean restricting them from normal movement and function. During our research, we found that there are more types of pollution affecting sea turtles than just plastic waste in the ocean. For example, the nitrogen runoff and arginine build-up settling in the sea turtle’s habitats is causing tumors
There are only about 35,000 nesting females left in the world, which may be larger than the decreasing rhino population, it is nowhere near where it should be. Leatherback sea turtles take a longer than most animals to reproduce, so harvesting their eggs takes a massive toll on the population. You could attribute this decline to other factors as well, but in certain areas poachers have removed up to 95% of the
This usually causes extinction within that species, and researchers have decided to do something about it. Although endangered animals are born in the wild, they should be sheltered and protected in nature parks because it helps decrease the amount of extinctions, allows a better and healthier environment, and the animals are protected from predators and human hunters. Endangered animals are to be kept in zoos because it decreases the amount of extinctions. Human activities have affected animals living in the wild dramatically throughout history.
