The scallop Amusium balloti, Placopecten magellanicus, Equichlamys bifrons, and Crassadoma gigantea had intermediate aspect ratios (Table 3).
The scallops Mimachlamys asperrima and Placopecten magellanicus took slightly but significantly less time, whereas Equichlamys bifrons and Pecten fumatus sank more quickly (Table 4).
The ratio of the soft tissue wet mass to shell volume was highest in Equichlamys bifrons and Crassadoma gigantea followed by Placopecten magellanicus with a slightly but significantly lower ratio (Table 3).
The phasic adductor muscle (corrected to 90-mm shell height) was heaviest in Crassadoma gigantea, Placopecten Magellanicus, and Equichlamys bifrons (Table 3).
Here, Equichlamys bifrons, Mimachlamys asperrima, and Crassadoma gigantea had the highest value, followed by Amusium balloti and then Placopecten magellanicus and Pecten fumatus.
bifrons the highest value, and the other species having intermediate values.
The overall phasic contraction rate was calculated relative to the test duration of 355 sec for all species except Equichlamys bifrons.
Because the behavior of Equichlamys bifrons was assessed visually, the phasic contraction rate could be estimated relative to time to fatigue only.
5 N; Amusium balloti and Equichlamys bifrons had intermediate levels at 4.
The scallops Equichlamys bifrons and Mimachlamys asperrima had the lowest ligament resilience at 0.
