In areas with approximately the same water depths (10-14 m), 12 m in our case, a farm site in Amvrakikos Gulf, mid-waters (about 4-8 m) seems to be more suitable for the larval settlement of several scallop species (primarily, Pecten yessoensis, Pecten alba, Chlamys opercularis, Pecten maximus) than closer to the bottom (Brand et al.
Dependence on a definition of glaucoma that requires observing optic nerve head morphology is particularly problematic in birds because the pecten prevents funduscopic examination of all but a small section of the optic nerve head.
The pecten also showed modifications at different larval stages with regards to the number and complexity of their spines.

To determine whether the ligament resilience, ligament opening force, and force deployed by the phasic and tonic adductor muscles varied with escape response strategies and shell morphology, these properties were compared in scallops (Amusium balloti, Placopecten magellanicus, Equichlamys bifrons, Pecten fumatus, Mimachlamys asperrima, and Crassadoma gigantea) with differing life habits and morphologies.
