Read the passage. Then answer
a cleaner wrasse eating parasites from a moray eel's
mouth
Cleaner wrasse are small fish that live in
tropical coral reefs. Wrasse are often
visited by larger fish, such as moray eels.
When an eel visits a wrasse, the wrasse
cleans the eel by eating parasites
attached to the eel's body. If the
parasites are not removed, the eel may
become weak or even die.
Before the wrasse begins to clean, the eel
opens its mouth to signal to the wrasse
that it is ready to be cleaned. Then the
wrasse eats all the parasites it can find
on the eel's body, including those inside
the eel's mouth!
Which type of relationship is formed when a cleaner wrasse eats parasites off a moray eel?
commensal
mutualistic
parasitic
