PRESENTATION OUTLINE
Parasitism : The snapper fish and Cymoth-oid isopod
The snapper fish and isopod share a parasitic relationship. The isopod degenerates the fishes tongue and replaces it, taking away blood, mucus, and stray pieces of food from the fish.
Commensalism: imperial shrimp and sea cucumbers
The imperial shrimp and sea cucumbers share a commensalism relationship. The shrimp attach themselves to the sea cucumbers, where they are taken around to food and once they find it, they get off, eat, and jump back on. The sea cucumber is not harmed or benefitted.
Mutualism: boxer crab and anemones
The anemone and boxer crab have a mutualism interaction. The boxer crab attaches anemones to it's claws resulting in the crab easily scaring off predators. In exchange, anemones eat the scraps of food left over from the crab.
Commensalism: sea turtles and barnacles
The sea turtles and barnacles have a commensalism relationship. Once the barnacles are attached, they are benefitted with food in nutrient-rich waters. The sea turtle, however, is neither harmed or benefitted.
The tapeworm places itself in the shark's intestines and feeds on its nourishment. The shark, on the other hand, becomes deprived and has a greater chance of disease and predation.
