Abstract

Lizards are ideal taxa in studying defensive behaviors, comparatively because they are prey for a wide range of vertebrate (Dubeux et al., 2019, Alcantara et al., 2014, Birkhead & Benny, 2014, Brito et al., 2014) and invertebrate predators (Sy & Alaban, 2014). Moreover, this group has evolved a broad defensive tactics in surviving potential predators (Dappen, 2010, Nunes et al., 2012, Brock et al., 2014, Patel et al., 2016). In literatures, there are two basic defensive behaviors that are known: primary defense involves cryptic coloration and locomotor escape (Nunes et al. 2012) and secondary defenses such as gular expansion, locomotor escape, cloacal discharge, threat display (mouth opened and trying to bite), tail wave, autotomy, and death-feigning (Dappen 2010, Santos et al., 2010, Nunes et al., 2012, Patel et al., 2016, Brock et al., 2014) when primary defenses failed.
