Bulb and hair follicle of a quill, visible deep pigmentation within the hair follice at the start of the quill, whilst pigment lacks on the bulb itself.
Picture of the bending at the start of the quill, just after the hair follice. Visible decreasing pigmentation from start of the quill towards the mid section.
Scale cast made of a quill of an Atelerix albiventris, visible dented pattern instead of hair scales, which is consistent with the air bubbles on the inside of the quill instead of airshafts.
Albino quill with clear lack of pigment over the entire hair follicle and start of the quill.
Albino quill in the mid section with a clear total lack of pigment.
Black quill at mid section. Visible increase of pigment at the start, creating a very dark brown banding.
Black quill at the tip with visible cream pigment on the very end of the tip that's slightly darker then with other colors.
Chocolate quill in mid section with visible increase of pigment resulting in cream banding.
Cinnicot quill with visible increase of color (picture is mirrored) resulting in an offwhite banding.
Dark Grey quill in the mid section. Hardly any banding visible as pigment slightly increases from the hair follicle towards the actual banding, resulting in hardly any difference in the start section and the mid section.
Grey quill in mid section, close-up. Slightly lighter colored then Dark Grey, resulting in a grey-brown color. Also hardly any banding visible on this quill as pigment slightly increases from the hair follice towards the actual banding, resulting in hardly any difference in the start section and the mid section.
Pinto quill in mid section. Barely visible offwhite pigmentation, in comparison to the fully white Albino quill. No visible banding and no increase or decrease of pigment noticed over the entire length of the quill.
The root of a hair from the belly of an Atelerix albiventris. No pigmentation and nearly seethrough at the base.
The middle part of a hair from the belly of an Atelerix albiventris. Visible coronal scale pattern, but pigmentless.
The tip of a hair from the belly of an Atelerix albiventris. End of the tip missing, visible damage.
Comparison of the quills of a wildcaught Atelerix algirus from Morocco and a wildcaught Atelerix albiventris from Togo. Visible difference in lenght, width and pigmentation between the two species.
Cross section of the quill of an Atelerix algirus with visible airshaft and air bubbles, connected by layers of keratin inside and a thick layer of pigmented keratin on the outside.
Tip of the quill that's visibly transparent with no pigmentation. Very slight and barely noticable bending of the tip.
Mid section of a quill with visible in- and decrease of pigment in the middle, creating a very narrow strain of pigment and a lot of banding from the start section to the midsection and the mid section to the tip.
Hair follicle and start section of a quill, with visible deep pigment within the follicle, decreasing fast into a cream-brown color.
Cross section of a quill. Visible airshaft with thick layers of keratin with air bubbles surrounding it and a thick layer of deeply pigmented keratin.
Outside of a quill, displaying a very smooth outside layer of keratin that's deeply pigmented.
Stereolight picture of the tip of a quill. Semi transparent keratin, making it nearly impossible to photograph with toplight, but too dark to use bottomlight. Very slight bending visible, no information on pigment.
The root of a hair from the belly of a Hemiechinus auritus. Visibly very thing and nearly seethrough and pigmentless at the base of the hair.
Middle part of a hair from the belly of a Hemiechinus auritus. Visible pale beige pigmentation on the hair as it grows thicker toward the tip and fading out a little bit just before the tip where the hair gets smaller again. Almost like a form of ticking.
The tip of a hair from the belly of a Hemiechinus auritus. Visible dark pigmentation on the tip of the hair.
Two types of hairs from a Tenrec ecaudatus, showing differences in pigment, shape and structure, with the thicker hair having more quill-like features than a hair.
Tip of the hair gradually becoming semi-transparent but keeping the pigmentation.
Hair follicle with lack of pigment and semi-transparent.
Mid section of the hair with visible hair scaling and increasing pigment from the hair follicle towards the mid section.
Damage on the hair, with visible cream colored keratin inside. Visible thin layer of dark colored keratin inside as well.
Cross section of the hair, with visible solid keratin layers inside surrounded by a dark pigmented layer of keratin and a lighter colored layer of keratin on the outside.
Scale cast made with clear nailpolish, making the hair scale pattern visible, showing an imbricate crenate scale pattern.
Close-up of the imbricate crenate hair scale pattern in the scale cast.
A quill of a Setifer Setosis. Visible bending at the root and wide banding in the middle.
The root of a quill of a Setifer setosis. No pigment in the bulb, highly pigmented base of the quill. Visible bending st the base of the quill.
Close-up on the denting pattern of the quill of a Setifer setosis. Visible banding from deep brown to beige.
Scale cast of a quill of a Setifer setosis. Visible denting pattern.
Root of a divergent quill of a Paraechinus aethiopicus. Divergent quill of 5mm long. Very high pigmentation, a lot of skin tissue attached.
Middle section of the divergent quill of a Paraechinus aethiopicus. Not an obvious denting pattern, but visible airshafts. Very blunt banding from deep brown pigment to beige.
Top of the divergent quill of a Paraechinus aethiopicus. Beige pigmentation, slightly patterened.
Banding and denting pattern of a quill of a Paraechinus aethiopicus. Pigment going from deep brown to beige. Less blunt then the divergent quill.
Close-up of the denting pattern on the outside of the quill of a Paraechinus aethiopicus, contrasted by the dirt in between the pattern.
Close-up of the denting pattern on a less pigmented part of the quill of a Paraechinus aethiopicus.
The root of a quill of a Paraechinus aethiopicus, with some skin tissue still attached.
