"Joker" crab（小丑蟹）

Zoologists recently found a weird new species, the purple "Joker" crab, on the beautiful Filipino island of Palawan. The scientific name of the crab is Insulamon palawanese. The island features enchanting beaches and majestic animals, and most impressively, about half of all the species found on the island cannot be found anywhere else on the planet. The crab bears a light resemblance to the Joker, the super-villain who appears in the "Batman" comic series, so it is also called the "Joker" crab.
