Step 1: Choose a Symbiotic Relationship

Question

After reviewing the lessons or doing some outside research, choose a symbiotic relationship between marine organisms to research. Perhaps you thought it was neat that barbel fish literally clean hippos’ mouths. (This is an example of mutualism.) Or maybe you were interested by the fascinating relationship that crabs and Sacculina carcini have developed. (This is an example of parasitism.)

Once again, the choice is yours! Just make sure you choose a symbiotic relationship between two marine organisms.

Step 2: Research
Use reputable online resources to collect some information about the symbiotic relationship you chose. For this step, you’ll want to do these things:

Find at least four interesting facts about the symbiotic relationship.
Find at least one photo of the two organisms in their symbiotic relationship.
Keep a list of sources you viewed.
Step 3: Present Your Findings
Once your research is complete, present the information you found in the form you chose to share your findings.

Step 1: Chosen Symbiotic Relationship - Cleaner Shrimp and Predatory Fish

For this research, I have chosen the mutualistic relationship between cleaner shrimp (specifically Lysmata amboinensis) and predatory fish, such as the moray eel. Cleaner shrimp are known for their role as “cleaners,” removing parasites, dead skin, and other debris from the bodies of larger fish.

Step 2: Research

Interesting Facts:

1. Mutualism: In this relationship, both parties benefit. Cleaner shrimp obtain food by eating parasites and dead tissue, while predatory fish, like moray eels, benefit from the removal of these harmful organisms, improving their health.

2. Behavioral Displays: When a fish approaches a cleaning station (where cleaner shrimp reside), it will often signal its intention to be cleaned by performing specific behaviors. This might include opening its mouth and gill covers to pose as an inviting target for the shrimp.

3. Coloration and Habitats: Cleaner shrimp are often brightly colored—usually red and white. They usually inhabit coral reefs and are found in the Indo-Pacific region. These bright colors signal to fish that they are safe and beneficial.

4. Communication: Cleaner shrimp have been observed to perform dances or movements to attract fish and communicate their readiness to clean. They might also produce specific sounds to signify their presence.

Title: The Symbiotic Relationship Between Cleaner Shrimp and Predatory Fish

Introduction: The mutualistic relationship between cleaner shrimp and predatory fish is an intriguing example of cooperation within the marine ecosystem. This relationship not only benefits the individual organisms involved but also contributes to the overall health of coral reef ecosystems.

Key Facts:

• Mutual Benefits: Cleaner shrimp feed on parasites and dead skin, enhancing fish health.
• Behavioral Signals: Fish express readiness for cleaning through specific movements.
• Vibrant Adaptations: Cleaner shrimp's bright colors serve as signals of safety and benefits to fish.
• Communication: Unique dances and sounds are utilized by shrimp to attract and communicate with fish.

Conclusion: The relationship between cleaner shrimp and predatory fish exemplifies the intricate dependencies that exist in marine ecosystems, emphasizing the importance of mutualism in sustaining ecological balance.
