Lol,animals live and thrive in areas where there is a constant supply of water and food,my self,i have seen wild boar,countless hyena,different varities of foxes,hipppos,gazelle, and even zebra that is just few km from balcad.
me and my grandma was attacked by brown hyena when i was 10 years ,so yes it has undocumented wildlife.
I will assume those were the peaceful times? And isn't balcad in jubaland where rivers flow I won't be surprised if few hyenas still roam but considering north Somalia is desert and no water resources how could wildlife exist?
