Figure 7 In situ shot, identified as Swiftiasimplex. This is what one would expect to see of live colony. Notice strong similarity to that seen in Figure 28, Part II. As specimen was not collected, identification cannot be confirmed. Image (02_57_27_20) courtesy of Lonny Lundsten and Kim Fulton-Bennet, "(c) 1992 MBARI."
