The bottlenosed Dolphin can easily be trained to do specific tasks,
just like a dog.
And the Porpoise is extreemely difficult to train, just like your
household cat.

Any real marine mamologist knows that.


Well, what can I say............. I had a cat that comes when I
whistle and would leave when I said "out"

How could i train a cat to do that? The same the way marine
entertainment industry train their odontocets ..
Here ya go, how do you get an odontocet to jump through a ring of
fire. After all theyre just a dumb fish right?

(Hint: Progressive approximation of the target behavior.)

But back to the porpoise dolphin debate........... There are NO
taxonomical diffrences between the two. Porposise and dolphine are
simply common names that lay persons use.

Go get this book. Its paperback and a typical NOAA white cover. It
will help inform you.

Id let ya use mine but i gave it to a 6th grade student some years ago
who was interested in pinipeds, a heated topic in the Columbia River
this last week.

Odontocets are a tremdous research area and a very popular topic. Good
luck with your search. When you have other questions please contact me
anytime.
Cordially,
