We are learning to write information reports. This is not a report that we wrote, but one that we think is a really good example. We have colour coded the different parts of the report to help us to remember to include them when we write our own reports.
Killer Whale information report
Killer whales are toothed whales. Whales have teeth that fit tightly together and are very strong. The killer whale is black and white in color, it has a sleek, streamlined fusiform (tapered at both ends) body shape. The average size of a male is 9m and the average size of a female is 5 meters.
This is a Killer Whale.
Killer whales inhabit all oceans of the world but are most numerous in the Arctic, the Antarctic, and areas of cold waters .They can be found near the shores of Washington, Oregon, California, and Baja California and along the eastern coast of the United States. Killer whales also have been seen in warm water areas such as Hawaii, Australia, the Galapagos Islands, the Bahamas, and the Gulf of Mexico.
When the killer whale swims it moves its powerful tail up and down, and beats the water with its flukes. It flippers help the whale to steer and to keep its balance in the water. A whale’s streamlined body and smooth skin allow it to slip easily through the water.
The killer whale is the top predators in the ocean; they are the largest predator of warm blooded animals ever known. The killer whale eats fish, squid, seals, sea lions, walruses, birds, sea turtles, penguins, polar bears, reptiles, swordfish and even a moose! All of these animals were found in a killer whale's’ stomach.
The female killer whale turns sexually mature when they reach 4.6-4.9m, at about 6-10 years old. The male killer whale turns sexually mature when they reach about 5.1-6.1m, at about 10-13 years old. In the Pacific Northwest calving is mostly occurring in the spring and fall. In other areas of the world, researchers have seen calves born throughout the year with no statistical evidence for birth seasons.
No one knows for sure how long killer whales live. Killer whales are top predators in the sea. Healthy adults have no natural predators, but sharks prey on older, younger, or ill killer whales.
Killer whales are smart and interesting to see.
