The document discusses different types of symbiotic relationships that exist between marine species. It describes commensalism through the relationship between pearl fish and sea cucumbers. Parasitism is defined as a relationship where one organism lives and feeds off another, potentially harming the host over time. Mutualism is exemplified by "cleaning stations" where small fish and shrimp remove parasites and waste from larger "client fish." Mimicry is also discussed using the example of the mimic octopus which can disguise itself as other marine animals like stingrays or sea snakes through both aggressive and Batesian mimicry for defense.

1. Marine Symbiosis

2. SymbiosisThe word symbiosis literally means 'living together.' In the context of marine biology this is referring to an intimate relationship between two different specieshttp://www.youtube.com/watch?v=xaJdXO_j2MY

3. CommensalismPearl fish /Sea CucumberPearl fish spends day inside the intestines of the sea cucumberAt night the fish comes out of the sea cucumbers butt to eat small crustaceansPearl fish benefits by getting a safe place to live while the sea cucumber is not harmed (Abbott 2).Humongous Sea Cucumberat Weird Sea MonstersHumongous Sea Cucumberat Weird Sea Monsters

4. ParasitismThis relationship involves on member (the parasite) living and feeding off another organism (host). The health of the host can be affected over time, depending on the parasite how long it lives inside the host.http://www.youtube.com/watch?v=pploDkZ07BI&feature=channel

5. Mutualism‘Cleaning stations’Wrasse, Gobies, Shrimps common fish-cleaning speciesFish being cleaned are called ‘client fish’Remove parasites, dead skin, tissue, mucous (Bordestein 2)http://www.youtube.com/watch?v=N87y02XvJls

6. MimicryMimic OctopusTakes on shape of different animalsMimics anything from sting ray to a Lionfish or a sea snakeUses both batesian and aggressive mimicry because its mimicry is for defense and protectionhttp://www.youtube.com/watch?v=ygh1-ul6E94
