Common name(s): Peanut worm

Phylum Sipuncula
 Class Sipunculidea
  Order Sipunculida
   Family Golfingiidae
Golfingia pugettensis trawled from San Juan Channel, WA at 90 m depth
(Photo by: Dave Cowles 7-2004)
Description:  This sipunculan has inconspicuous, fingerlike, unbranched filiform tentacles (at the anterior end of the introvert), around the mouth (picture).  The introvert (extensible anterior end) has no dark bands or streaks or rows of hooks near its anterior end.  Its length is equal to half the body length (or nearly so).  The skin is nearly smooth ( papillae are present but small).  Color is whitish to gray.

How to Distinguish from Similar Species: G. vulgaris has an introvert less than half its body length, its skin is rough with papillae, and the color is dark brown.  Phascolosoma agassizii has dark and light blotches and streaks on its introvert.

Geographical Range:  Also found in the Sea of Japan and in Prince William Sound, Alaska

Depth Range:

Habitat:  This specimen was trawled from the San Juan Channel at 90 m depth by otter trawl.  Substrate was sand/shell hash

Biology/Natural History:

Note:  The genus name was created by the British zoologist Sir E. Ray Lankester (for another species in the genus) to commemorate a holiday of golf at Saint Andrews, Scotland.
