The exhibit originally held three walruses. Later two passed away and one surviving male was transferred to Seaworld Orlando. In 2002, the zoo received two sea lions along with harbor seals.
They might be fat tailed or greater mouse lemurs that lived in Jungle Trails. I'll check when I go back next week. The shoebills were also in Jungle Trails which opened in 1993 but I'm not sure when they were taken off. Kudu21 may answer that for you.
