Some species of shrimp are considered “fish cleaners” because they feed on parasites that infect fish. The fish that are cleaned are sometimes called “client fish.” As well as removing parasites, the cleaner fish remove and consume dead skin, tissue and excess mucous. This maintains the health of the “client fish” in return. The Shrimp get the nutrition from the fish, and the fish get the benefits of being cleaned.
Tapeworms are segmented flatworms that get their name from their long, flat appearance. These worms live in the intestines of mammals such as pigs, cows and even humans. They get food by eating the host’s partially digested food, depriving the mammal of nutrients; also, the host will develop a secondary infection in the process.
In the marine biome, the great white shark is the apex predator. It usually preys on elephant seals. For seals, the best line of defense is to stay on land. For the great white shark, its exceptional hearing skills help to locate the seal. It is not always possible for the seal to stay out of water, because it can die of hunger. The moment it gets into the water, it is on the great white's radar. It all comes down to whoever blinks first.
The Texas Sage has a complex root system that is able to absorb more water quicker than most other desert plants this make it able to acquire nutrients and water faster than other plant species when water is available. This makes the Texas Sage better at survival than other species of plants in the area.
Barnacles are ocean crustaceans. In adult form, the animals are sedentary, unable to move. As juveniles, they swim through the ocean and perform a metamorphosis into the adult form, attaching themselves to the body of a whale or other marine organism. The barnacle benefits by finding a habitat and having access to nutrients. The presence of barnacles does not appear to either benefit or harm the whale.
