Figure 2. A common inhabitant of the San Diego Trough 

 at 4100 feet is the brittle starfish, probably Ophiomsium 

 lymani or Ophiotrix sp. Many such starfish were observed 

 to be buried with only the tips of their arms protruding 

 from the sediments. These are believed to be a species 

 other than those observed on the surface. An unidentified 

 lavender sea cucumber (Holothurian) with well- developed 

 pseudopods moves slowly across the green sediment. 

 Numerous worm tubes are terminated by a palmate- form 

 exposed end (probably achaetopteran). They extend up 

 from the sediments and appear as dark clumps throughout 

 the figure. A puff of sediment is being extruded from a 

 mound in the far background. Numerous lavender and 

 white heads of nontube dwelling worms were also observed 

 but are not recorded by the film. The large starfish, 

 upper right, is the only one seen at this location.
