Mouflon vignei" (or "orientalis") "arkal" and "O. v./o. bochariensis", grouped with two different clades of argali ("Ovis ammon"). The ancestral sheep is presumed to have had 60 chromosomes, as in goats ("Capra"). Mouflon and domestic sheep have 54 chromosomes, with three pairs (1+3, 2+8, 5+11) of ancestral acrocentric chromosomes joined to form bi-armed chromosomes. This is in contrast to the argali and urial, which have 56 and 58 chromosomes respectively. If the urial is as closely related to the mouflons as mitochondrial DNA indicates, then two chromosomes would need to have split during its evolution away from the mouflon (sub)species. In
Domesticated hedgehog mind that they are much like dog's nails in that their nails contain a bit of skin. Therefore, this should be done carefully and it is best if done after a shower, since the hedgehog's nails will be softer. Hedgehog nails can be trimmed with a cuticle cutter or baby scissors.
