It gives the impression that something new has been discovered. So in this case is a clickbait, you have to click and find out something that is known, maybe not well known but I wouldn't say a secret. I personally knew about Orcas attacking sharks.

I think you filled in the blanks with a 'new discovery', when your brain could have simply assumed that the title would be "A discovery of a new animal that scares even the Great White Shark!" if there was a new discovery.

I think it is click-bait in the literal sense, but not in the negative connotation that click-bait is used today.
