According to viewers of the Discovery Channel’s latest hit documentary on whales, renowned naturalist Sir David Attenborough was having a really tough time properly conveying the sheer enormousness of blue whales.

“Imagine if about 25,000 cardboard boxes each contained one three-toed sloth,” Attenborough explained, providing a perplexing analogy for an adult blue whale’s weight that almost nobody, even a sloth expert, could relate to. “To put it more simply, that’s around 20,000 boxes each housing a two-toed sloth. Simply amazing, isn’t it?”

Attenborough proceeded to ditch the familiar scientific units of “number of school buses” to discuss the length of the largest animal known to have ever existed on Earth. “Close your eyes for a second and picture approximately 10 Andean condors lined up next to each other with fully outstretched wingspans,” Attenborough narrated, not realizing that that very few people were capable of picturing any regular bird, let alone an Andean condor, with an outstretched wingspan.

Attenborough concluded the segment on blue whales by marveling at how these absolutely humongous creatures required a heart about 16 times as heavy as a mountain beaver’s brain.
