The animal that can't swim is the giraffe. Giraffes have long legs and a heavy body, which makes it difficult for them to stay afloat in water. Additionally, their long necks make it hard for them to keep their heads above water. This combination of factors makes it nearly impossible for giraffes to swim effectively.
Long necks go back to the dinosaurs when there were Lamarckian mutations.
