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
They eat: plants, fruit, tree sap, small lizards,
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.
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.
The only animals they eat are spiders,and worms. They hardly ever eat those animals they eat mostly leaves on their diet.
Red Ear Turtles love to be outside of water better than in, even tho they are made to be in the water. If they stay in land for too long they can dry up and
What does the otter eat? Sea Urchins How does the consumption by the otter effect the growth of the Kelp forest?
Let’s start off with where it lives. It lives in wetlands, swamps and upland forests. They can be seen in Arkansas, Mississippi, Alabama, Georgia and Florida. Its habitat is a diversity of warm climates. They must live in an area with a fairly big water source
Manatees live in north american east coast, shallow slow moving rivers, saltwater bays, canals, and the coastal areas. They eat seagrass and freshwater vegetation. They are losing their habitats they really need to live. The migration route for a manatee in winter and summer is back and forth from the east and west coast of Florida.
Today otters face other threats. Apart from disease epidemics, otters continue to be threatened by overharvest, interactions with fisheries (e.g. gear entanglements), oil spills and being prey to killer
The author states that the pollution hypothesis seemed the most likely cause of otters decline along the Alaskan coast and provides three reasons. In contrast, the professor states that the ongiong investigation show that the predation theory is mst likely the cause of the decline and sh.e opposes each of the author 's reasons First, the reading claims that there were known sources of pollution along the Alaskan coast. However, the professor refutes this pint by saying that the pollution theory is weakened by that no dead sea otters were washed up to the shore. She said thet if the infection is the cause of the decline, there should be a lot of killed otters washed up, so this fact is consistent with the predation theory because if the sear otters were killedby predetors, they would not wash up to the shore.
Sloths usually only go the forest floor to defecate, this makes them very vulnerable but when in the trees their color, slow movement and the algae on them acts as camouflages. A sloth’s fur is specialized to grow in the away from the sloth’ body to protect it from the weather when the the sloth is upside down and some of the sloth’s fur have tiny cracks that can collect water .Sloths are folivores, they mainly eat leaves and plant material , some two toed sloth sometimes will eat insects and other small animals. Since sloths mainly eat leaves, it does not give them enough nutrients they need so they have specialized chambered stomachs to slowly digest their food. Sloths also have very low metabolic rates and they have low body temperatures. Researchers have found out that sloths in the wild actually sleep about 10 hours a day and don’t sleep for fifteen or more hours like captive

1911, Southern sea otters swam on every coast near the Pacific, Including the Sea of Japan. They lived in large kelp forests near shores and would usually stay on the surface of the water only diving when food was necessary. Being the most important part of the food chain, sea otters kept anything that would eat the seaweed like snails, and sea urchin populations in check so the kelp forests wouldn 't die out. Southern sea otter populations near the west were unknown, but the American east coast has around “15,000 otters through 1911 to 1928 and growth kept going”(The Monterey Bay Aquarium).
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.
