Classification: Animalia, Bilateria, Siphusauctidae.
Species: S. gregarium (type), S. lloydguntheri.
Diet: Filter feeder.
Size: Up to 20 centimetres.
Known locations: Canada, British Columbia - Burgess Shale. USA, Utah - Spence Shale.

Fossil representation: Several individuals.
is a genus of filter feeding animal that lived on sea floors during the
mid Cambrian era. Roughly shaped like a bell pepper on a stick,
the main body of Siphusauctum was attached to the
sea floor with a
hold fast. With the body held up off the sea floor, Siphusauctum
passed water through its body. Any small creatures or organic
particles trapped in the filters of the body would then be digested.
