Venus Flower Basket

TheVenus's Flower Basket, or Euplectella aspergillum, is the only Poriferan in the phylum Hexactinellidae to be used in hobbiest's aquariums. This is due to the fact that Hexactinellid sponges are mainly deep ocean sponges that are not suitable for domestic aquarium environments. In traditional Asian cultures, this particular sponge was given as a wedding gift due to the fact that cetain shrimp tend the paricitize them. The sponge would be dried and the shrimp would be caught inside, symbolizing eternal bonding.
