MUTUALISM

  • A mutualistic relationship is when two organisms of different species "work together,"
  • One example of a mutualistic relationship is that of the oxpecker (a kind of bird) and the rhinoceros or zebra.
  • Spider crabs live in shallow areas of the ocean floor, and greenish-brown algae lives on the crabs' backs, making the crabs blend in with their environment, and unnoticeable to predators. The algae gets a good place to live, and the crab gets camouflage.**
  • A well-known example of mutualism is the relationship between ungulates (such as Bovines) and bacteria within their intestines.

PARASITISM

  • Parasitism is a non-mutual symbiotic relationship between species, where one species, the parasite, benefits at the expense of the other, the host.
  • Classic examples of parasitism include interactions between vertebrate hosts and tapeworms, flukes, the Plasmodium species, and fleas.
  • Examples of ectoparasites include the Rocky mountain wood tick, Dermacentor andersoni, and a mosquito. Mistletoe, is an example of an epiparasite, called an aerial parasite. A plant parasite, is a parasite that attaches to the branches of trees or shrubs.
  • Some aquatic leeches, for example, locate hosts by sensing movement and then confirm their identity through skin temperature and chemical cues before attaching.

COMMENSALISM

  • commensalism is a class of relationships between two organisms where one organism benefits without affecting the other's parts.
  • Anemonefishes or clownfishes - These live amid the tentacles of the anemones which protects them from predators. Predators are poisoned by the nematocysts of the anemones.
  • Barnacles - These will attach to whales or mollusk shells in order to be where food is available. This also acts as transportation for them and safety.
  • Hermit crabs - These crabs have to find shells for shelter and use various snail shells. These shells are available because the snail has died; so, the snail is not affected.
