Despite the promise of bloodthirsty camels and conniving zebras, CBS’ Zoo this Tuesday night ticked down to match its series lows, drawing 5.8 million total viewers and a 1.0 demo rating.

Elsewhere, NBC’s America’s Got Talent (10.4 mil/2.2) was steady yet dominated the night in both measures, while Hollywood Game Night (4.9 mil/1.4) rose 18 and 27 percent.

Fox’s 5th Grader (2.3 mil/0.5) and ABC’s Extreme Weight Loss (2.2 mil/0.6) were flat.
