Transcript of Shrimp & Anemone - A Symbiotic Relationship

Tubeworms & Bacteria
A shrimp is a decapod crustacean. Shrimp feed along the sea floor near coasts and estuaries. There are many types of shrimp, including rock shrimp, pink shrimp, brown shrimp, etc. Shrimp is among one of the most popular seafood in our world today, with over seven million tonnes produced every year. Most shrimp are found in the ocean - salt water - but, 25% of the known species of shrimp are found in freshwater. For this project, we will focus on the sea-dwelling species of shrimp, so we can observe the relationship between it and the sea anemone.


Sea anemones are predatory sea animals that live along the ocean floor. Even though they look stationary, they do have the ability to move. When trying to catch their prey, sea anemones release toxins in an effort to capture and digest it. Sea anemones are a very successful species, having been on this Earth for 300,000,000 years. Obviously, they have changed quite a bit since then, but their lives' principles have stayed the same. Sea anemones depend on species of shrimp in order to keep their existence stable.
As said in the beginning of this presentation, the shrimp and sea anemone are very dependent upon each other. Basically, the shrimp and the sea anemone have a "commensalistic" symbiotic relationship. The shrimp cleans the surrounding area of the sea anemone, eating its parasites and the slime that forms around of the anemone. In turn, the sea anemone provides protection from the many predators of the shrimp. Both organisms benefit from this; therefore, they together have a symbiotic relationship that if often called commensalism.
The tubeworand the bacteria in the video had a very distinct relationship, as we described on the previous slide. Their interaction between each other can be described as "commensalism". As we've found out, there are other types of symbiotic relationships between other animals living near the vents. They're all similar to each other, and both organisms of each symbiotic relationship could or could not benefit from it. All in all, the tubeworm and bacteria have a very unique relationship.
As seen in the video earlier, the tubeworms and their bacteria also have a type of relationship, just like our two organisms. Although they both have relationships, they have different types. While ours is a symbiotic relationship, these two creatures have an anti-microbial relationship. This means that the tubeworm does not benefit from it. The tubeworm provides a safehouse for the bacteria, and the bacteria feed off of the insides of the tubeworm, but the tubeworm does not get harmed from it. All in all, these two have a very important relationship to keep their species alive.
