Oceanic Sharks Clean at Coastal Seamount
Figure 4
Observed distributions of cleaner fish inspections of pelagic thresher shark clients in 1,230 hours of remote video on 232 days over 16 months (July 2005 to December 2009) (center), with ethogram (around).
Red lines represent cleaner inspections (n = 2,757) and were mapped according to their respective locations on pelagic thresher shark clients as observed from remote video. One line represents 20 inspections. 1) A pelagic thresher shark decelerated to 60.34±7.55 video frames per body length 2) a cleaner (A) rose to the pectoral fins 3) another cleaner (B) rose to the pelvis as the former (A) inspected the left pectoral fin 4) pectoral (A) and pelvis inspections (B) 5) caudal inspection (B) 6) cleaner (B) returned to the substrate 7) pectoral inspection (A) 8) cleaner (A) returned to the substrate.
