New Habitat

This is the new habitat I created for the blue whale. The habitat's temperature is about 50 degrees Fahrenheit. The whale habitat/tank is 600 meters (length) x 600 meters (width) x 300 meters (height) in size. The main plants are red algae, seaweed, seagrass, and kelp. The whales' main food source is krill. Sharks and fish are just some of the many animals that live there.

Physical Adaptations


The blue whale have baleen plates to filter the krill they feed on. This has a positive effect in the new habitat because there is krill in the new habitat for them to feed on.

The blue whale has a huge layer of fat called blubber around them to keep them warm. This has a positive effect in the new habitat because the habitat is colder.

Behavioral Adaptations


Since blue whales are mammals, they gave extended parental care for their young. This has neither a positive or negative because nothing eats or harms the blue whale besides humans.


Since they live in water, an adaptation allows it not to sleep. If they slept, they would drown, so they only take short naps. This has a positive effect because they still live underwater.


Whales migrate from warm waters to cold waters or vice versa. They go to warm waters to give birth, and they go to cold waters to eat. This has a negative affect to the new habitat because the tank isn't big enough for them to migrate.


Introducing the blue whale to a totally new environment can create a big impact on it. That is because it could have a different food and new animals around it. Also, the climate could be different. For example, the temperature in my habitat could be too warm for them so they might die or reduce the blubber around their bodies.


The blue whale is an endangered species because its population is rapidly declining. One reason that it is endangered is that it is being over hunted by whalers. The whales' body parts make products such as soap or oil. Also, it can die or get sick because of pollution or if it eats something toxic or poisonous or something it's not supposed to. There could also competition over food or space.
