they can probably wee and poop out of the same hole because we have two but its not like they are human is it.
Yes
No, they are certainly not. Blue whales and killer whales both belong to the same order: Cetacea, the order of the whales. Though that's where the liking stops. Because Killer whales belong to the suborder Odontoceti (toothed whales) and Blue whales belong to the suborder Mysticeti (baleen whales).
No, But they are from the same family of animal.
Killer whales, orcas, are toothed whales, but they're not the only ones.
Killer Whales are actually dolphins. They are the largest member of the dolphin family.
No. Killer whales swim in waters that are at the same latitude as the taiga, but the taiga is strictly a land biome.
They are the same thing.
They all look about the same to me.
Bottlenose Dolphins and killer whales/orcas are two different species. They're both mammals though.
Same as any other whale.
No. Goldfish do not inhabit that same environment as killer whales do. Goldfish are not marine animals.
