Mutualism occurs in the relationship between remoras and sharks, where remoras eat parasites off of sharks to keep them healthy and in return receive protection and food. Clownfish also have a mutualistic relationship with sea anemones, where the clownfish protects the anemone from fish and receives protection from its stinging tentacles. Goby fish and shrimp also engage in mutualism, with the shrimp digging a burrow for them to live in and the goby warning the shrimp of danger so they can retreat to safety.

1. Symbiosis Mutualism
• Mutualism occurs when there is a relationship between
two different organisms, in which each partner benefits
from the relationship.
• There are studies that : the remoras clean parasites from
the shark's teeth and perhaps skin. If this is true then it is
a mutualism relationship. Remoras eat the parasites off
the underside of the shark to keep it healthy and alive.
Plus the Remoras get a free meal and protection. A
mutualistic symbiotic relationship.

2. • An example of mutual symbiosis is the relationship between the
clownfish that dwell among the tentacles of Ritteri sea anemones.
The territorial fish protects the anemone from anemone-
eating fish, and in turn the stringing tentacles of the anemone
protect the clownfish from its predators. A special mucus on the
clownfish protects it from the stinging tentacles.

3. Another Example
• Another example is the goby fish, which
sometimes lives together with a shrimp. The
shrimp digs and cleans up a burrow in the sand in
which both the shrimp and the goby fish live. The
shrimp is almost blind, leaving it vulnerable to
predators when above ground. In case of danger
the goby fish touches the shrimp with its tail to
warn it. When that happens both the shrimp and
goby fish quickly retreat into the burrow.
