       Siphusauctum 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.
