Janubiy Amerika qit’asidan Tinch okeaniga quyiladigan daryolar And tog’larining g’arbiy yonbag’rlaridan oqib tushadi va ular nisbatan kichikdir. Shuning uchun ham yuqoridagi jadvalda ushbu qit’a daryolarining asosiy gidrologik va morfometrik ko’rsatkichlari alohida aks ettirilmadi.
Jadvalda keltirilgan ma’lumotlardan ko’rinib turibdiki, havza maydonining hamda oqim hajmining kattaligi bo’yicha Amazonka daryosi yer yuzidagi eng yirik daryo hisoblanadi. Uning havza maydoni (Ukayali bilan qo’shib hisoblaganda) 6915 ming km² ga, o’rtacha ko’p yillik oqim hajmi esa 6930 km³ ga teng. Uzunligi bo’yicha esa, geografiyaga oid adabiyotlarda qayd etilganidek, Nil daryosi (Kagera nomli irmog’i bilan qo’shib hisoblaganda) ajralib turadi va uning uzunligi 6670 km ni tashkil etadi.
