Venus Flower Basket: Brighter then Evolution Real Science: The Venus' Flower Basket, or Euplectella aspergillum is a hexactinellid sponge in the phylum Porifera inhabiting the deep ocean. In traditional Asian cultures, this particular sponge (in a dead, dry state) was given as a wedding gift because the sponge symbiotically houses two small shrimp, a male and a female, who live out their lives inside the sponge. They breed, and when their offspring are tiny, the offspring escape to find a Venus Flower Basket of their own. The shrimp inside of the basket clean it, and in return, the basket provides food for the shrimp by trapping it in its fiberglass-like strands, and then releasing it into the body of the sponge for the shrimp. It is also speculated that the bioluminescent light of bacteria harnessed by the sponge may attract other small organisms which the shrimp eat. The glassy fibers that attach the sponge to the ocean floor, 5-20 cm long and thin as human hair, are of interest to fiber optics researchers. The glassy fibers that attach the sponge to the ocean floor, 5-20 cm long and thin as human hair, are of interest to fiber optics researchers. The sponge extracts silicic acid from seawater and converts it into silica, then forms it into an elaborate skeleton of glass fibers. Other sponges such as the orange puffball sponge can also produce glass biologically. The current manufacturing process for optical fibers requires high temperatures and produces a brittle fiber. A low-temperature process for creating and ...
NOAA Ship Okeanos Explorer Extraordinary "Highlight" video offshore Kona, Hawaii A compilation of video clips collected in deepwater by the Little Hercules Remotely Operated Vehicle and camera platform during an ROV shakedown cruise aboard NOAA Ship Okeanos Explorer offshore Kona, Hawaii (March 2010). The video footage shows a pelagic sea cucumber (apodid holothurian), Venus flytrap sea anemone (actinoscyphiid sea anemone), tipod fish (chlorophthalmid tipod fish), flatfish (pleuronectiform flatfish), eel (bongrid conger eel), shrimp (benthic caridean likely nematocarcinid shrimp), actiniid Bolocera-like sea anemone with a galatheid crab, Glass sponge and demospongid with hermit crab, and hexactinellid (glass) sponge next to a primnoid coral.
