The world production of pectens, a bivalve mollusks, in 2007, was 12,616,738 t, generating 11,740,962 dollars (FAO, 2009).
These authors, Barber and Blake (2006), in 2006 wrote that the pectinid Pecten maximus displays seven stages, those being: (0) immature; (1) development; (2) differentiation; (3) recovery; (4) swelling; (5) initial maturation; (6) advanced maturation; and (7) partial or total spawning.
For Pecten maximus in Galicia (Pazos et al., 1996), the spawning period is most intense during the winter (12.0 to 12.7[degrees]C) and spring, when the temperature reaches 16[degrees]C.

The pecten oculi is a highly vascular and pigmented structure peculiar to the avian eye [1-3].
Three morphological types of pecten oculi are recognized as conical, vaned, and pleated types.
Histologic studies have shown that the pecten oculi consists of blood vessels, extravascular pigmented cells, and superficial covering membrane [1].
Significant variations in the pecten oculi such as type and number of pleats exist within the avian species due to the behavior of birds in relation to their general activity and visual pattern.
The eyeballs were cut at the equator, and the posterior half which contained the pecten oculi was photographed using digital camera attached stereomicroscope (Nikon SMZ-2T, Nikon Corp., Tokyo, Japan).
