"SCP-2256 was the largest species to have lived on Earth. Resembling spindly, vertically elongated giraffes or brachiosauruses, adults of the species grew to over 1,000 metres in height. They weighed no more than 4 tonnes, with most of their mass being "camouflaged" by a very similar adaptation. With their broad, dish-shaped feet, they were able to walk directly on the surface of the ocean without sinking.
The first and only close-up photograph of one of the creatures instantly killed it."
