The male (peacock) Indian Peafowl has iridescent blue-green or green colored plumage. The so-called "tail" of the peacock, also termed the "train," is not the tail quill feathers but highly elongated upper tail coverts. The train feathers have a series of eyes that are best seen when the tail is fanned. Both species have a crest atop the head.
The female (peahen) Indian Peafowl has a mixture of dull green, brown, and grey in her plumage. She lacks the long upper tail coverts of the male but has a crest. The female can also display her plumage to ward off female competition or danger to her young.
The Green Peafowl is different in appearance from the Indian Peafowl. The male has green and gold plumage and has an erect crest. The wings are black with a sheen of blue.
Unlike the Indian Peafowl, the Green Peahen is very similar to the male, only having shorter upper tail coverts and less iridescence. It is very hard to tell a juvenile male from an adult female.
Many of the brilliant colours of the peacock plumage are due to an optical interference phenomenon, Bragg reflection, based on (nearly) periodic nanostructures found in the barbules (fiber-like components) of the feathers.
Different colours correspond to different length scales of the periodic structures. For brown feathers, a mixture of red and blue is required: one colour is created by the periodic structure, and the other is a created by a Fabry-Pérot interference peak from reflections off the outermost and innermost boundaries of the periodic structure. Many colour mutations exist through selective breeding, such as the leucistic White Peafowl and the Black-Shouldered Peafowl.
Such interference-based structural colour is especially important in producing the peacock's iridescent hues (which shimmer and change with viewing angle), since interference effects depend upon the angle of light, unlike chemical pigments.

explain what is anatomy
Medical anatomy is very detailed. Paramedical anatomy is general.
One can get a syllabus for general anatomy and physiology from the Digital Library. These are also available at Mineral Area and DR Holly Typepad.
Alfred von Behr has written: 'Handbook of human anatomy' -- subject(s): Accessible book, Human anatomy, Anatomy 'Handbook of human anatomy, general, species and topographical' -- subject(s): Accessible book
Well, their are numerous species of Peafowl. if you mean Pavo Cristatus, or Indian Blue Peafowl, Pavo Muticus, or Green Peafowl, or just Pavo for peafowl in general (the genus of birds).
In all fields and in general use, the opposite of "superior" is "inferior".
There are two species of peacocks*. The Indian peacock is considered Least Concern (which means it is not endangered whatsoever). The other species, the Green peacock (or Javan), is endangered. In general, endangered species are protected, however I can't find any information on conservation programs for the green peacock. *The real name for peacock if peafowl. Scientifically, "peacock" is used only for males, peahen for females, and peafowl for both.
i think that a green peacock is just a normal peacock like a indian peacock
Gross anatomy, also called macroscopic anatomy, is the study of structures which can be examined without the use of a microscope. Therefore, it can be said that gross anatomy is based on features which are observable with the naked eye.
The axial region. The limbs are the appendicular.
For the associates degree, the anatomy and physiology, and the microbiology are required.
