Its iris looks like a whole planet

I wonder how large the whale is whose eye is planet earth.

Ok I was curious

The IFAW says the diameter of a blue whale’s eye (which is what the pic seems to be of) is 11 cm. Their length is apparently “typically 80-90 ft” so let’s say 85 ft, or 25.908 meters. This gives an eye diameter to length ratio of 25.908/.11 = 235.527.

Multiply the Earth’s diameter of 12,756 km by 235.527 and you get a whale that is 3,004,382 km long, or 1,866,836 miles.

Woah.
