Killer whales have 52 teeth. Females can live to be 80-100 years, but their usual is around 50. Males can live up to 50 years, but their usual is 25. Sadly, most orcas in captivity usually only live 15 years. They live in all the oceans, the only thing that blocks their freedom is land and icepacks.
Orcas use echoloction to find their prey and each other.
I will put your screen name next to your fact unless you don't want me to. Please put the subject as Orca Fact. I now have two different guestbook. The old one is still at the bottom. OrcaCool is now part of a webring.
