Have students view videos to identify symbiotic relationships.Show students the three videos of different marine species interactions. The animal kingdom offers many examples of how species can coexist in mutualistic relationships under beneficial terms, or at least causing the least amount of annoyance to each other. All rights reserved. Another facultative mutualistic relationship, ed mangrove provides the sponge with carbon, nitrogen the sponge releases gets eaten up by the mangrove to enhance growth, goby will then live in the entrance of that burrow, shrimp exits the burrow, it will stay in contact with the goby through its antennae, Goby fish with shrimp photo via Wikimedia Commons under public domain, General characteristics of a large marine ecosystem (Gulf of Alaska) photo via Wikimedia Commons under Public Domain, source@https://tropicalmarinebio.pressbooks.com/.

You Feed Me, I Feed You: Symbiosis - Dive & Discover Watching these unlikely couples work together and exist harmoniously, I think thats kinda sweet.

(competition) Ask students to again think about and discuss the benefits of studying animal behavior and ecological interactions without interference by human observers. 6. The shrimp and goby fish relationship is another mutualism example in the ocean. However, the shrimp has difficulty seeing and detecting predators so its goby partners would flick its tail to warn the shrimp of any danger. The whale reaps no rewards from the barnacles attached to its body, but it also does not suffer any ill effects. Or perhaps you could be the one leaching off someone else.

Mutualism also occurs between spider crabs and algae. You can often find a remora swimming close to a sea turtle. Ask: How do ecological and symbiotic relationships shape your imaginary marine ecosystem? Remoras Galore: Commensalism on Coral Reefs Give small groups time to complete the activity.Answer any questions students may have. Explain that in this activity students will use a series of videos, images, and scenarios to identify and discuss examples of ecological and symbiotic relationships in the ocean. The imperial shrimp first finds a sea cucumber. After each video, have the class identify and discuss the symbiotic relationships they observed. Sometimes there are definite losers.
