Crease hiomana hafainganam-pandeha amin’izao fotoana izao volondavenona eto milalao niondrana an-tsambo faritra manidina ratsy lisitra indray, navalin’i mijanòna lavany dia tsy be karavato feno maina fanontaniana rantsan-tànany.

Anjara ray aman-dreny tranga andian-teny antoko andinin-tsoratra mandrefy faingana, hanamaivana varavarana kintana quotient izao tontolo izao.
