You could argue that that isn't clickbait because it is a technically correct answer, but it would be nice to see an actual source for the human/whale food consumption.
There is an article about the same paper on How Stuff Works that is definitely clickbait: "Each Year Spiders Eat Millions of Tons of Food More Than Humans".
Edit: I don't know if I know what click bait means.
Clickbait is over-sensationalising a title to bring more traffic to the article page, where ads and other monetising things can be served.
HN has been going bonkers over complaining about clickbait titles recently... it seems our denizens have somehow developed a highly-tuned sense of what clickbait looks like... but for some reason still can't resist clicking on it when they see it.
Why exactly is that clickbait? It's not suggesting spiders are cattle rustling or too lazy to farm.
