Date 1
Community
Creatures such as whale sharks, sea turtles, and chimaerans all live together in this region, therefore forming a community.
Community
Organisms
- Hawksbill turtles
- Fin whales
- Albacore tunas
- Bluefins
All of these creatures are organisms.
Organisms
Species
The hawksbill, sea, loggerhead, leatherback, and green turtles are all the same species.
Species
Habitats
A lagoon of reefs and coral atolls is the habitat of a whale shark.
Habitats
Niches
Sea turtles - Maintain the sea
grass beds
Whale sharks - Plankton patrollers
Bluefin tuna - Provides temperature variety
These are examples of Coral Triangle organisms' niches.
Competition
While corals try to rebuild themselves, they compete with seaweed for space. This is an example of competition in this region.
Competition
Predation
Examples of predation:
Plankton --> Whale shark
Mollusks --> Loggerhead turtle
Parasitism
A tongue-eating louse isopod ("fish lice") is an example of parasitism, since it extracts blood from the tongues of fish hosts.
Parasitism
Mutualism
A primary example of mutualism would be a clownfish and a sea anenome. The anenome provides a safe home for the clownfish, and the clownfish provides food to the anemone.
Mutualism
Commensalism
Whales and barnacles is an example of commensalism, since the barnacles attach themselves to the whales giving them a free ride and plenty of food. The whales gain no advantage or disadvantage.
Commensalism
Keystone Species
Corals are a keystone species in this region, because without them, numerous marine organisms won't have shelter and food.
Keystone Species
Marine turtles are an edge effect, since numerous amounts of plastic affect them.
