Choose an animal to write a research report on. In your report include:

A diagram and explanation of the animals life cycle

• A description of the animal's daily behaviors (learned and instinctive)

• The animal's niche (habitat, predator, prey etc)

The animal's role in a food chain and food web

The animals habitat​

Killer Whales, A male killer whale’s lifespan is usually around 30 years but he can, in fact, live up to about 50-60 years; a female usually lives till 50 but, in some cases, lives up to 90 years of age. Female killer whales mature faster than the males. Killer Whale's daily behaviors consists of  breaching (jumping), travelling, tail slapping and socializing. Social Behavior; The social structure of the killer whale is quite complex and stable. They live with their mothers for their entire lives.

Killer Whales have many prey, for which they are very big so they can hunt basically anything. Some feed exclusively on fish, while others hunt marine mammals such as seals and other species of dolphin. They have been known to attack baleen whale calves, and even adult whales.

But for habitat, depending on the ecotype, killer whales may exploit a variety of habitats, from shallow coastal areas to deep waters off the continental shelf. Killer whales are found in the open ocean, but they seem to be most abundant in coastal waters. In ocean ecosystem killer whale have a big part they use the environment as part of hunting techniques. In Antarctica a whale may push up on to an ice floe and slide over it to catch a penguin. They are also known to bump into ice floes and knock prey off into the water. This concludes my report on Killer Whales.
