Lizards have been a regular hazard at the grand prix, with Max Verstappen's Red Bull race engineer Gianpiero Lambiase dubbing one particularly large specimen "Godzilla" in 2016.
When a smaller one emerged during last year's practice, Lambiase suggested "maybe Godzilla had a kid".
Monitor lizards are typically shy, according to Singapore's National Parks' Board, unless cornered. They are also diurnal, meaning they sleep at night - a relief for organisers of the night race.
