Today I’ll be telling you about my favorite dolphin. The Killer whale (Orcinus orca), also referred to as the Orca whale or Orca, and less commonly as the Blackfish, is a toothed whale belonging to the oceanic dolphin family.

1. Killer whales, also called Orcas, are the largest of the dolphins. They are divided into 4 ‘types’ labeled A, B, C and D – each set has its own identifying features.
2. To tell a male and female Orca apart just look at their dorsal fins. Male dorsal fins are larger than a females and the females have a smaller curved dorsal fin.
3. Killer whales are found in all the oceans of the world.
(The blue areas are where they are found, see they are all over!)
4. Killer whales have 40 to 50 teeth that are up to four inches long.
5. The average life span of a killer whale in the wild is 50 to 80 years old.
6. Orcas are sometimes called the ‘wolves of the sea’ because, like wolves, they hunt in packs.
7. Killer whales can grow to be 23 to 32 feet long, almost as long as a bus.
8. Orcas are one of the fastest creatures in the sea, traveling up to 30 miles per hour.
9. A Killer whales’ brain is five times larger than a humans. They are very social, intelligent, and curious. Killer whale brains that have been studied with microscopes have proven to be as structured and developed as the human brain.
10. Their use of clicks, whistles and pulsed calls help them communicate with their pods and locate food.
11.The only recorded instances of a Killer whale attacking a human being have been by Orcas held in captivity. No Killer whale that lives in the wild has ever attacked a human being.
