Okay, so a flying squid is not too surprising to most people, since there are a few species of squids that can propel themselves out of the water for a few seconds. But in Jun Yamamoto's case, he was tracking a school of oceanic squids during a research boat trip, and that's where the moment hit him.
A school of twenty or more squids were seen flying across the ocean waters at a speed faster than Usain Bolt, and Yamamoto considered this action as their means to escape from hungry squid craving predators. In light of this event, Yamamoto realizes that the abilities of these squids can turn them into a full course menu for sea birds that fly by. Thus adding some new information to his research on oceanic squids.
Surprising or not, it's not too often that one gets to see a school of flying squids -- unless if you're a fisherman. I will admit that this was the first time that I've heard of these squids, so I was fascinated their method of gliding by shooting water at a high pressure. All in all, they are way cooler than flying fishes in my book, so I give them a +1.
