There's a real art to the photobomb: it's all about timing, positioning, and basically just ruining somebody's photograph in the funniest way possible.
The shot above is an epic example. That seagull clearly thought it was about to get some much-needed attention, and then boom. Whale.
It was posted by Twitter user @raubrey on Sunday, and it's gotten a lot of attention (although not everyone's convinced it's real - there are some Photoshop rumours floating around).
Seeing the epic shot got us thinking about some other great photobombs from the animal kingdom we've come across online, so without further ado, here are our Top 15 Animal Photobombs:
