of food per day for some large male otters. Their diet being mainly sea urchins, the sea otters keep the urchin population under control which allows for other life within the kelp ecosystem to survive and create a balanced ecosystem. Without the sea otters in a kelp ecosystem, the sea urchins can take over and disrupt the ecosystem by killing out some algae species and some fish which live in the
In captivity, there’s nowhere for them to go, which leads to injuries and death.” The text supports my claim because it shows that Orcas cannot live with their mothers in captivity and they might get in fights and hate other Orcas because they are not the same and don't speak the same language. However, in the wild, Orcas stay and live with their mothers and don't get in many fights. Also, the text supports my claim because it shows that Seaworld is not treating Orcas right and having too many orcas in the same area which results in fights and anxiety which increase the chance of orcas murdering each other and they want to find
We can only move forward from today and do as much as we can to make the Pacific Ocean a safe place for these species. It comes from simple things such as picking up small pieces of litter and making sure litter goes in the trash
Hammerhead sharks are carnivore because they eat meat much as fish species. They will eat fish to regain their energy because they use most of it swimming. They also use energy by using their sense of smell that allows them to detect blood. When a shark reaches a point when they can’t use any more energy, they will go deep into the ocean and stay there. Their preys won’t spot them as easily when they are deep in the ocean.
“If all the beasts were gone, men would die from a great loneliness of spirit, for whatever happens to the beasts also happens to the man. All things are connected.” The Hawaiian monk seal is the nation’s most endangered seal, and one of the world’s most endangered marine mammal. With enough resources scientists can make progress toward achieving and to help maintain a healthy population of these endangered monk seals, but it will not be easy. Preventing interactions between people and seals is a responsibility is something these organizations are going to have to manage.
What a bottlenose dolphin eats and also likes to eat for fun and play with. As you would think that a dolphin would eat seaweed and many other vegetable like ocean plants,they actually do not eat them. Bottlenose dolphins have been known to eat crustacions,many small types of fish,and squids but a smaller version of them. An adult bottlenose dolphin eats 15 to 30 pounds of food a day and bottlenose dolphins do not use their teeth to chew but actually they just swallow their food whole.
While otters are considered secure globally, the southwestern stock in Alaska is threatened. According to Alaska's Department of Fish and Game, http://www.adfg.alaska.gov/index.cfm?adfg=seaotter.main "in southwest Alaska, sea otters have experienced a sharp population decline in the last 20 years," while the Southeast and Southcentral stocks have stabilized or increased. In an email exchange with Webber, he told me that the otters washing up were assumed to be non-threatened Southcentral northern sea otters because of the location of where they came ashore. Otters have a unique history in Alaska. They bounced back from the fur trade, that began in the 1700s, that almost wiped them out.
Without the Sea, they will become endangered, perhaps even extinct.
AP Environmental Science: Chapter 5 1. Explain how southern sea otters act as a keystone species in kelp beds. The otters help to keep sea urchins and other kelp-eating species from depleting highly productive and rapidly growing kelp forests, which provide habitats for a number of species in offshore coastal waters. Without southern sea otters, sea urchins would probably destroy the kelp forests and much of the rich biodiversity associated with them.
Human impacts on Kelp forests could create an absolute advantage in the kelp community. These men and women work, to filter these kelp ranges. They are located near the eastern Pacific. Kelp is a brown color probably due to lack of oxygen or chemicals within biological chromosomes. in some point between our currents, the kelp can stick to your boat.
Overhunting has had an effect on several different species, the one I will be telling you about is the Harp seal. The harp seal is located in the “west ice” of eastern Greenland, in the “east ice” of eastern Russia, and off the cost of east Canada and are currently being over hunted by humans. Harp seals, and others like the Namibian cape seal, are currently slaughtered more than any other marine mammal in the world. Harp seals are usually 3 weeks to 3 months old when they are clubbed (being hit with a club, like a golf club, until you dead), bludgeoned (being hit in the head with a large, heavy object really hard), or shot to death by a few hundred or a few thousand fishermen, depending on how well they can get to the seal, each year.

Although the orca can be found in both in the open ocean and in the coastal waters, they primarily inhabit the continental shelf’s in the water less than 200 meters deep. In the cold water area is the most distribution limited by the seasonal pack ice. The killer whale is the top carnivore consumer on the food web. Killer whales may be large in size and appetite, but they still act on instinct and have no desire to kill intentionally. The killer whale is also a very playful and intelligent creature like most dolphins are, therefore they do not deserve the name killer whale.
The differences between the diving patterns of the resident and transient killer whales are due to their variations in their diet and hunting habits. Resident killer whales generally feed on fish in the near-shore region. They tend to forage for herring or salmon cooperatively in large social groups. Since they move in large groups, it is difficult for them to hunt for food in short intervals.
They are very unique in many different ways and a crucial support for human life. They play also a very important role in the marine life such as giving shelter and food for millions of species including fishes, crabs, or shrimps. They support 33% of marine fish species. They also have specific and certain conditions to be formed, and to survive. They are also known as the “rainforest of the oceans” because of its huge diversity.
