About half a million, blue-green color jellyfish are expected to hoard in this summer along the coast of Ibiza, Spain’s most popular Balearic Island. The blue-green color of the jellyfish is owed to their consumption of sea algae, resulting in them being almost invisible to the naked eye. These jellyfish are a rare breed that only surface (if at all) in leap years.
For travelers planning a trip to Ibiza this summer, not to worry, the jellyfish are not poisonous and do not bite. In fact, it is known to be pleasurable swimming with them as you feel them subtly tingle against your body.
Also, these are probably the only type of jellyfish in the world that are edible and have aphrodisiac properties. Sweet and acidic in taste, they are served with ice-cream as a rare dessert delicacy of the islands.
