The actual title of the article is "The ecological impact of spiders" with the submitted title being the byline. While the actual article's title is not clickbait, the submitter clearly went with the byline to attract more interest.

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".
