Common name: Chelidonura

Scientific name: Aglajidae

Aglajidae, commonly known as headshield slugs or Chelidonura, are a family of cephalaspidean gastropod mollusks. They are characterized by their unique head shield used for burrowing into the sand and a tail that often has a forked appearance. These creatures are known for their striking colors and patterns, making them a fascinating addition to the reef aquarium. They are beneficial as they consume flatworms, including the pesky planaria, which can be problematic in reef tanks. However, they require a well-established tank with a sand bed and plenty of live rock to thrive.
