What I Learned Today
Today I learned that there are two types of killer whales - residents and transients. Resident killer whales are the cute, friendly ones we see on tv, happily splashing about and snacking on fish and squid. Transient killer whales travel far out to sea in pods of 1-7. Transients are hardcore. They hunt as a pod and dine on marine mammals as big as blue whales - the largest animals on earth.
Incidentally, killer whales (orcas) are not whales at all. They are actually a variety of dolphin.
