Dolphin Brain Capacity

I think that dolphins are smarter than humans, for a simple reason:
Cause I never heard of a dolphin killing another dolphin.

I am not sure that it has never happened but they certainly seem to form
long lasting and contented social groups.

Sorry to burst your bubble, but it does happen. In Scotland,
bottlenose dolphins have been seen harassing and killing harbor
porpoises and recently evidence has emerged of infanticide in the same
population (five out of 8 dead bottlenose dolphin calves found
stranded had apparently been killed by adult bottlenose dolphins
(Patterson et al, 1998)).

Also note that aggressive (but not necessarily fatal) interactions
have been regularly recorded in many populations (spotted and
bottlenose dolphins in the Bahamas, for instance, see Herzing and
Johnson (1997))

Dolphins can be aggressive towards each other. It should also be noted that
bottlenose dolphins have been recorded systematically killing the harbour
porpoise.

While on the subject of how "smart" dolphins are please follow the two links
below.

NB: Chimps have been known to kill each other and also kill and eat other
primates!

Hi!

You do not have to be sorry about anything. I happy that you have
ligthened me up about this fact.
I always read stories about Humans harrasing dolphins, but until now I
never read anything about Dolphins harrasing other Dolphins.

Thanks and bye!

Wow, that makes them so much like intelligent humans doesn't it?
