J is for Jameos Del Agua, which is located in the north of Lanzarote. It is part of a cave system in the island’s volcanic rock (the Atlantida volcanic cave system) formed by the eruptions of a volcano about three to four thousand years ago.
Inside the cave, which has a collapsed roof, is a salt water lake (Jameo Chico). This lake contains a species of tiny blind albino crab that is unique to this place. I found the cave with its lake to be very photogenic, and spent some time trying to get images that gave me a sense of this cave, but alas failed to capture images of the minute crabs!
