Lemur cata
----------
English: Ring-tailed lemur
German: Katta
French: L‚mur
Spanish: Lemur
Distribution areas
------------------
The ring-tailed lemur and other species
of the genus lemur live only in the forests
of the Madagascar and surrounding islands.
Description of the fur
----------------------
The skins of the ring-tailed lemur is up The cuticular structure
to 40 cm long; the tail measures about 50 of the fine fibres, 1000x
cm. The coat is dense, soft and grey in
colour. The head is black, but the belly part and inside parts of the legs
are white-grey in colour. The tail is black and white ringed.

Structure of the hair
---------------------
The microscopic structure of the skin
surface is furrowed and the hair follicles
are narrow with straight edges. The hair
fibres grow from the follicles alone.
The fine fur fibres have a diameter in
the range of 10 to 25 µm. Their The cuticular structure
cross-sectional outline is circular or of the fine fibres, 1000x
elliptical in the middle and upper part of
the shaft. The cuticular scales are cornet-like with a smooth scale surface
and straight scale margins. The medulla is usually narrow, unbroken and
central symmetrical-shaped in the cross-section. The overall structure is of
the uniserial ladder type with an amorphous infilling substance.

The intermediate fibres have a diameter
in the range of 20 to 30 µm. The
cross-sectional outline is elliptical and
the shafts are covered by a cuticle
composed of even, tile-like scales. The
cuticular surface is smooth and the margins
are straight. The medulla is narrow,
unbroken and central symmetrical-shaped in
cross-section. The medullary structure is Longitudinal section
of the uniserial ladder type. The detailed of a fine fur fibre, 4000x
structure of the infilling material is
amorphous.
The guard hairs are elliptical in cross-section with diameters of 30 to 45
µm. The cuticular scales are even, tile-like and crenated, tile-like in the
upper parts. The scale surface is smooth and the margins are straight but, in
the upper parts of the fibres, the margins are rippled.
