I think that there are seven teams if I’m not wrong: lower vertebrates and invertebrates, birds, large mammals 1 (often called rhinos), large mammals 2 (often called giraffes), small mammals (often called twilight), primates and carnivores.
What about the elephants, do they have a team of their own? On Secret Life... they seem to have their own keepers who don't appear with any other species, though I appreciate that isn't the best indicator!
Whilst we're on the subject of the staff teams, am I correct that the Asian Short Clawed Otters are looked after by the giraffe team - and if so, does anyone know why? It just seems really illogical to me!
