This crafty crab was caught using a jellyfish as a disguise and a living shield.
Skittering along the Filipino seabed while gripping hold of a jellyfish – this crab has specially adapted back legs to help.
The unusual crab hopes it jellyfish disguise will protect it from marine predators such as octopus.
It was Chet King, 63 that captured this footage – the lab supervisor has over 40 years of diving experience and a passion for all marine creatures.
Chet said: “When I turned my video light on to video the motion of a jellyfish it began to shake and turn. The jellyfish emerged from the bottom and started running as witnessed in the video. It was alive and well but attached tightly to a carry crab.
“Without the jellyfish the crab could be easy prey for an octopus or other marine animals that eat crabs. I have witnessed this behaviour on many occasions with the crab using sponges, sea urchins, and other objects like coconut shells and bamboo sticks for protection.
“This crab is in the family Dorippidae. They have modified back legs that they use to grip things for camouflage and protection.
“I have been a certified diver since 1969, a PADI instructor for 40 years and currently a PADI Instructor Alumni.
“I love everything about SCUBA diving but the most thrilling thing now is seeing anything I have never seen before.
“I will travel to the other side of the world to see something as small as a sea slug or as large as a whale shark and be equally impressed.
“This video seems to evoke a reaction of shriek, laughter, and curiosity. Everyone seems to enjoy a story of ingenuity and survival.”
