0 any part of the body that is like a comb (= a long object with a row of thin, narrow parts for making the hair neat) --
Pecten oculi is abundantly filled with melanin granules which have been proposed to absorb stray light entering the bird eye to reduce background glare.
The eye's internal anatomy is similar to that of other vertebrates, but has a structure, the pecten oculi, unique to birds.
The pecten pubis forms part of the pelvic brim.
The pecten is a specialised structure in the avian retina.
The pecten is also used to preen feathers and to hold slippery food items.
Characters: the head is smooth, antennae four-fifths to one, basal joint thick, with slight pecten.
The pigmentation of the pecten is believed to protect the blood vessels against damage from ultraviolet light.
The avian eye also contains a structure called a pecten oculi, which is a comb-like projection of the retina.
