Fig. 11. Lifestyle strategies in plesiosaurs. A. Feeding beneath the body on mesoscopic prey (average diameter 5–10 mm and 100–200 mm), probably shoaling within the water column. B. Feeding on similar sized prey from within soft sediments. C. The escape response, with the neck approximately straight in front of the body, and held rigid by the presence of a dorsal ligament system, thereby permitting relatively rapid motion with minimal muscular effort to hold the head and neck anterior of the locomotor apparatus.
