How do remoras communicate?

Howdy ckkrish!

The Columbus Zoo & Aquarium web site has all sorts of interesting
information on remoras, including the fact that they are fish:
http://www.colzoo.org/animalareas/shores/remora.html

"The remora is a fish whose dorsal fin has adapted into a sucker-
like organ that attaches to larger marine animals."

So maybe the question is how do fish communicate? 
 
According to the American Museum of Natural History:
http://www.amnh.org/nationalcenter/kids/kids_bio/scientist.html#8 
 
"Q: How do fish communicate?"
 
"In many different ways. Fish live in water which is very different 
from air. If I wave my hand in the air - you see it but you don't 
feel it. But you would feel it in water. Every time a fish flicks 
its tail or fins it sends waves of energy over very large distances. 
So fish have developed the senses to communicate with these distant 
waves. It's called distant touch. They use it for navigation, and 
for sensing their surroundings. Some fish use electric fields also. 
They can also hear and see just like us."

Here are some excerpts from the Pagewise, Inc./allsands.com "Fish
Talk" page.  Even more of the article can be viewed at:
http://www.exsands.com/Science/Animals/fishcommunicati_sey_ex.htm 
 
"Fish are specifically sensory oriented animals. Different groups of 
fish communicate in different ways with different sorts of languages. 
These languages are called pheromones."
 
"What is a pheromone?  "
 
"Pheromones are chemicals that carry messages that produce behavioral 
responses in other fish."
 
"How do fish communicate using pheromones?"
 
"Pheromones can communicate a number of messages ranging from whether 
or not danger is looming, food is present, or mating is to occur."
 
"How do fish communicate using body pattern changes and colors?"
 
"Fish can also change their color as an indicator of their mood. The 
way a fish changes depends on their species."

Fish talk

Fish are specifically sensory oriented animals. Different groups of
fish communicate in different ways with different sorts of languages.
These languages are called pheromones. 

What is a pheromone? 

Pheromones are chemicals that carry messages that produce behavioral
responses in other fish. Different species of fish uses different
chemicals, which usually makes it hard for different species to
communicate with each other. 

How do fish communicate using pheromones? 

Pheromones can communicate a number of messages ranging from whether
or not danger is looming, food is present, or mating is to occur. The
reactions to pheromones are automatic and observable under certain
circumstances. Social pheromones exist as well, cueing fish in on
whether or not they are too crowded together or lonely etc. 

How do fish communicate using body pattern changes and colors? 

Fish can also change their color as an indicator of their mood. The
way a fish changes depends on their species. They also use these
color changes to aid mating and fighting rituals. Some can even
control pigments that produce stripes on their bodies, which confuse
predators
chasing them.

Thanks  for your prompt response. I would like to close by making
payment to you. As I am new to Google Answers I am not sure what is
the procedure.

Thanks again,

Ckkrish_real,

Since Denco is not a Researcher, he or she cannot post in the answer
spot and there's no reward possible other than the "thanks" you gave.
In the future, you can differentiate Researchers and non-Researchers
by checking if their user name is a link or not when comments or
answers are posted.
Hope it helps!

ckkrish - Just go ahead and close the question; since I am
not an "official" Google Answerer, there would be no charge.

Glad to have been of some assistance.
