One of the strangest forms of sea life contained in these tanks is the Spirographis, a kind of worm which builds out of its own body tubes about a foot long and as thick as small gas hose. The tubes project out from the rocks. From the end of the tubes the worm extends a flowerlike spiral plume that waves backward and forward, gathering minute sea life for its nutriment.

The largest form of marine life contained in the aquarium is the conger eel. The most amazing thing in connection with them is that they swim backward with as much speed as they do forward. But while the live fish and other sea life are, of course, the most interesting, and the visitor emerges from the depths with a feeling of actually having been at the bottom of the sea, the collection of fish preserved in glass bottles on the main floor of the building is much more extensive and represents some very rare findings made in years of cruising and fishing at great depths. For this work special nets were required. In the enormous east hall on the first floor, the entire space is given over to an exhibition of the instruments used in gathering sea life at depths as great as 19,680 feet.
