A crab eating a whole jellyfish

I took this video of a crab grabbing the Portuguese Man o’ War jellyfish off the beach and taking it back to it’s sand hole to eat. I love the way the bigger crab washes up and chases the smaller crab with the jellyfish. This was taken at Bellows Beach, Waimanalo, Hawaii. Until we noticed this was happening we were wondering why the beach was clear when we sat down, then slowly we counted more and more jellyfish washing up. Suddenly the crabs were out searching the beach and removing the jellyfish!
