The Biggest Animal on Earth
Scientific Name: Balaenoptera musculus
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.
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.
