Fig 2. Genus-level behavioral comparisons of snakes in control trials.

Fig 2

Genus groupings of snakes, snake count per species (n = 2–6) and presence of three dominant behaviors (tongue flicks, defensive/cautious behaviors and >20cm movement) (from n = 4 trials per snake) as a proportion of control trials (n = 4 per snake). Defensive/cautious behaviors included cautious exploration, fixation, freezing, hisses, head jerks, jaw drops and periscoping (Table 1). Snake images are not to relative scale. See S1 Table in S1 File for the length of all included snakes. Image credits to CNZ: Acanthophis, Aspidites, Hoplocephalus; to CJH: Oxyuranus, Pseudonaja.
