In polymorphic ma.ma.ia. species tha. displa. multiple color forms, those with da.k. or mela.ic pela.e would be prone to overhea.ing, especia.ly if they live in wa.m clima.es, beca.se their fur a.sorbs sola. energy a. a.higher ra.e. However, experimenta. studies indica.e tha. certa.n physica. properties of fur of da.k.individua.s a.pea. to prevent, or minimize hea. stress, a.though it is not clea. wha. properties do so. Here, we tested the possibility tha. bla.k.furred individua.s simply ha.e shorter or thinner ha.r fibers, which would crea.e a.lighter （in terms of weight） coa. or one tha. a.lows grea.er a.r flow for eva.ora.ive coo- ling. We exa.ined museum specimens of ea.tern fox squirrels Sciurus niger, a.species na.ive to the United Sta.es a.d one tha. displa.s brown, grey or a.l-bla.k.pela.e color, a.d used ima.e a.a.ysis procedures to qua.tify ha.rs from the dorsa. surfa.e a.d ta.l. From exa.ina.ion of 43 specimens （19 brown, 9 bla.k.a.d 15 grey）, a.d 1,720 ha.rs, we found no significa.t difference in ha.r lengths a.ross color morphs, but significa.t differences in ha.r fiber widths. Bla.k.squirrels ha. thinner body ha.rs tha. other forms （7% thinner）, but thick.r ta.l ha.rs （9% thick.r） tha. the others. Given tha. the dorsa. surfa.e would be directly exposed to sola. ra.ia.ion, we interpret this to be a. a.a.ta.ion to prevent hea. stress during the da.. The thick.r ta.l ha.rs ma. be a. a.a.ta. tion for nighttime thermoregula.ion, since squirrels sleep with their ta.ls wra.ped a.ound their bodies. These results a.d to a.growing litera.ure body of the functiona. significa.ce of ma.ma.ia. pela.e [Current Zoology 57 （6）： 731-736, 2011].
