Killer whales, are really dolphins
« on: 20/12/2007 13:19:43 »
I recently heard that killer whales (Orca) are actually dolphins! The story goes that dolphins have this great PR team who happily portray dolphins as always smiling human friendly creatures. When the truth is far more sinister.

is this true?

also, why do dolphins always look like they are smiling?

Seriously Are dolphins really aggressive? I always thought them to be gentle when I have seen them...

Orca and dolphins are closely related, but not the same (unless someone has some information I am unaware of).

None the less, dolphins are carnivores, so they are killers in their own right; and they are one of the few animals that can frighten large sharks.

I have known for a while that Killer Whales are actually part of the Dolphin family and
mammals too.

Yes the reason that Dolphins are aggressive is for food or territorial reasons or to protect
their young. Same goes for Whales as well but they are both carnivores unlike some fish which
are either carnivore, ominvores or herbivores.  :-\
