Continued inspection reveals that additional images are required for a species diagnosis. If it were that clear cut, you would have nailed it the first time through. Lets face it - the pic is not going to clear this up. More pics and such are going to be needed before anyone states anything as fact. Unless you happen to have a few, or a few thousand of these buggers to look at, as the case may be.
Well, reveals it "to me". And to define "first time through", the process of identifying a crab is a step by step process, as you go deeper and deeper into the details of coloration, structure, markings, and proportion. At each level of depth, the crab will closely resemble a certain species or two, but there are obvious discrepancies, which require further inspection, and continued revision of your conclusion.
Levels of inspection are:
1. General inspection:
A. Color
B. Eyes
C. Legs
2. Closer inspection:
A. Secondary colors
B. Back left leg angle, curve, and twist
C. Antennule color
D. BP shape (if closed picture) and stitches
3. Deep inspection:
A. Eye shape, eye side markings or color
B. Antennae/antennule size in proportion to body, antennule tip color, antennae base size and color.
C. BLL point of angle, depth of box.
D. BP coloration pattern, lower color patch extend and division lines, structure.
E. BP/Feeder proportion
F. Leg proportion to eyes and body
G. markings on edges of legs
H. Joint coloration, leg thickness
I. Carapace side markings, and rear "Tatoo" marking
I am not sure this is an absolute truism. Lets face it, there are many islands in that part of the world, and many small currents, some of which may preclude genetic mixing and set the stage for speciation, subspeciation and such. It is entirely possible that there are color variants of many species that we are yet unaware of. I would expect that there are also a few species or subspecies that are as yet undiscovered. I am waiting for the dwarf coconut crabs that never get larger than 12 inches across. That would be awesome as I can't build a second house for one!
"Insofar" just means to such an extent, an a priori asumption, which may or not be correct, but to which the rest of the statement relies.
That said, I'm willing to build a second house for the full sized Birgus Latro!!!
As for the next crab species we discover, I think without a doubt they will be "Raspberries", "Thimbleberries", "Boysenberries", "Loganberries", and "Blackberries". After that, we will discover the "As", "Eyes": "Os" and "Yus", followed by the "TTs" and "DDs". The furriest species will be the "Carpets", and transparent ones will be the "Windows".
I definitely agree, that it will probably be a Coenobita Enthusiast who succeeds in breeding them.
