This is a video (actually two videos from different angles with one playing after the other) of a red octopus chasing a swimmer crab to eat. Things do not go according to the octopus's plan. I don't want to ruin it for you, so you should just watch it while I try to choke down this meal-replacement shake I'm supposed to be drinking for my diet. "That's just a McDonald's Shamrock Shake." Please don't tell my doctor.
Keep going for the video, but place your bets before it starts.
Thanks to Ilana, who heard that crab found God shortly after the incident.
