Ankizivavikely roa, mainty sy fotsy, no nifandona teo ambony fandriana

Description: Koa satria efa mahazatra azy ireo ny anatomie vehivavy, dia tsy tafintohina ao anaty haizina ireo tovovavy roa ireo rehefa mifankatia. Mifandona eo amin’ny latabatra fanorana ireo vatana maizina sy mazava rehefa mirehitra ny labozia.
