Fig. 6. Plot showing an ontogenetic change in the maximum rate of mantle contraction. Each point represents the maximum rate of mantle contraction during the escape jet for one individual. H, J1, J2 and Y2 refer to the life history stages of Segawa (1987) and correspond to Hatchling, Juvenile 1, Juvenile 2 and Young 2, respectively. See Materials and methods for more detail on the life history stages of Segawa.
