A parasitic relationship is one in which one organism, the parasite, lives off of another organism, the host, harming it and possibly causing death. The parasite. On this website, you will find information on these parasites including what they look like, where you'll find them on fish and how they may impact on their host. The cleaner shrimp gets its food from parasites or dead skin cells inside the The sea cucumber hosts the pearl fish inside its intestines that keeps the fish safe .
Organisms will also avoid competition through cooperative relationships within the ecosystem. Fish are frequently found existing in more than one symbiotic relationship. For example, a fish can have parasites and be cleaned by another organism living on its body. The parasites on the fish are food for the organism cleaning the fish. It is important to note that symbiosis only takes place between two different species.
Commensalism Commensalism is a symbiotic relationship where one species provides protection for another less mobile or more vulnerable species. The relationship between Clownfish and anemones is a well-known example of commensalism.
Clownfish live in the stinging tentacles of sea anemones.

They are coated in mucous, which protects them from the anemone's stinging nematocysts. Other animals like crabs and shrimps also seek protection in anemones.
The Anemone crab lives in the anemone's tentacles and catches its food without ever leaving the safety of the tentacles. Another example of commensalism can be seen with the Man-of-War fish and the Portuguese Man of War jellyfish.
Cooperation within the sea abounds and sometimes takes a very unusual form. Some Imperial shrimps will actually ride on sea cucumbers, hopping off when they want to feed in certain areas.
When the shrimp is ready to go to another area, it will hop back on the cucumber and be taken to the next place without using very much energy. Sometimes Imperial shrimp will ride on other animals like nudibranchs, and these animals offer protection to the shrimp because they are poisonous to other animals. Several species of sea cucumbers host the Pearlfish inside their intestines during the day. At night, the Pearlfish swims out of the anus of the sea cucumber to eat crustaceans.
The sea cucumber doesn't seem to mind this odd guest and the Pearlfish is relatively safe during the day. Parasitism More often than not, parasites are harmful to the host organism. Their life cycles can include two, three, or even four different hosts, such as Ribeiroia ondatrae, which first infects a snail, then a fish or tadpole, then a mammal or bird at different points in its life cycle!

The parasite Hematodinium infects a variety of different crustaceans including crabs, hermit crabs, and lobsters. In cold water-dwelling crab species, such as the snow crab, Hematodinium causes Bitter Crab Diseasewhich makes the crabmeat taste like aspirin.
How do you make a male crab behave like a female? It takes more than lipstick.
What causes oysters to lose the strength to go on? Parasites can be particularly problematic when they manage to invade a new geographic location. Parasitic plants and fungi can attack animals.
A fungus causes lumpy jaw, a disease that injures the jaws of cattle and hogs. There are also parasitic plants and fungi that attack other plants and fungi. A parasitic fungus causes wheat rust and the downy mildew fungus attacks fruit and vegetables.
Some scientists say that one-celled bacteria and viruses that live in animals and harm them, such as those that cause the common cold, are parasites as well. However, they are still considered different from other parasites.
Many types of parasites carry and transmit disease. Lyme disease is trasmitted by deer ticks.
