Transcript of The Indian Ocean

The Indian Ocean

Some adaptations that marine animals have adapted are that mammals like dolphins, whales, and killer whale have blubber that help them survive in cold weather. Every fish can breathe in the salt water and can filter in their lungs. This allows fish to live in water and survive. Another adaptation is that animals like the mimic octopus, the crocodile fish, and the cuttlefish have the ability to camouflage with their surroundings to prevent being eaten. Animals with collapsible lungs can dive deep underwater without getting hurt because of the high water pressure. Animals like the sperm whale can dive over 1 1/2 miles underwater, and the leatherback sea turtle can dive up to over 3,000 feet. Both of those organisms have collapsible lungs, which allows them to dive extremely deep.
Food Chain
The Indian Ocean
The Indian Ocean's Ecosystem
There are all important factors of this ecosystem. The most important abiotic factors of the Indian Ocean are the water temperature, the sun, the salinity of the water, and the oxygen in the water. Each of these abiotic factors are important for this ecosystem.
Symbiotic Relationships
Some symbiotic relationships in the Maldives are:
Mutualism between a clownfish and an anemone. A clownfish has the ability to make shelter in an anemone because it contains chemicals on its body that help it not get stung.They both benefit because the anemone gets protected by the clownfish, and the clownfish gets a home.
Parasitism between an isopod and warm blooded animals. Isopods are known as the mosquitoes of the sea. They go around and suck blood from unsuspecting animals. Isopods are benefited because they get blood (their food) and the organism that the isopod sucked blood from, gets harmed.
Commensalism between barnacles and whales. Some species of barnacles make their homes on top of whales or turtles.The barnacles get exposure to nutrient filled waters while riding on the whale or turtle, and the turtle or whale is not helped or harmed.
Keystone Species
A keystone species of the Indian Ocean is the green turtle. The green turtle is a keystone species because it is one of only a couple of animals that consume sea grass. Sea grasses are pretty alike from lawns because they need to be cut to stay healthy. If the green turtle population didn't exist, the sea grass would continue to grow. In a matter of time, the sea grass would become long and unhealthy because the turtle won't be consuming it. Many marine animals breed and develop in the shelter of the sea grass. If the sea grass became wild, untamed, and unhealthy, the animals that use the grasses can die out. Depending how high they are on the food chain, the rest of the animals will become extinct.
The species of the Indian Ocean
By Katelyn Mihalko
The Indian Ocean is the world's third largest ocean. It expands from Africa to Australia.
The Manta Ray
The manta ray lives in coral reefs and they consume zooplankton. Getting plankton sometimes isn't easy because there is competition between the manta ray and other fish. Although to zooplankton, a manta ray is a predator, to the shark, a manta ray is prey. The manta ray's niche is that it's a sea bottom filter and feeder because it feeds on the algae in the bottom of the sea. An example of a symbiotic relationship of the manta ray and the remora. The remora gets a meal, and the manta ray gets all the dead skin cells and parasites off its body.

The dolphin lives all over the ocean and lives in pods of 6-20 dolphins. It consumes squid and fish, but sharks and killer whales consume the dolphins. The niche of a dolphin is that its an apex predator and keeps the squid and fish population in balance.A mutualism symbiotic relationship is shared between the dolphin and the remora. The dolphin has all the bad parasites eated off by the remora which gets food.
Ghost Crabs
The ghost crab's habitat is made by the crab burrowing into the sand. The ghost crab is a scavenger and a consumer. For food, the crab either eats turtle eggs, clams, or other crabs, or scavenges for food on the beach. The niche of this animal is that it keeps the turtle population down. There was a mutualism symbiotic relationship between the ghost crab and a tern (a type of bird). The ghost crab eats a tern carcass for food, and the tern carcass doesn't spread diseases on it's body.
Green Turtle
The green turtle can live in many different habitats depending on it's age. When It is young, it lives on the beach. Once it is older, it swims on the surface of shallow waters, inshore bays, or lagoons. The niche is that it's an animal that It consumes sea grass. There is a mutualism relationship between the turtle and the yellow tang. The yellow tang eats the algae off of the turtle's back. The yellow tang gets food, and the turtle gets the algae cleaned off of it.

The Indian Ocean's Biome.
The Indian Ocean is a marine biome for different reasons. This biome is completely submerged underwater. It is not a land biome. Also, the Indian Ocean's ecosystem supports animals that live in water. It supports fish, plankton, coral, and other animals that need water to survive. The Indian Ocean is a part of the ocean biome because it is one of the oceans that covers over 70% of Earth.
