It does not usually spread a hood nor hold up its body up off the ground like true cobras do. [102] The mortality rate of untreated bites is not exactly known, but it's said to be very high (>80%). [86], The venom is possibly the most toxic of any Bungarus (krait) species and possibly the most toxic of any snake species in Asia, with LD50 values of 0.09 mg/kg[73]—0.108 mg/kg SC,[15][87] 0.113 mg/kg IV and 0.08 mg/kg IP on mice. [125] However, wild specimens have an average venom yield per bite of 280–450 mg (dry weight) (U.S. Dept. The muscular lightweight body of the Taipan allows it to hurl itself forwards or sideways and reach high off the ground, and such is the speed of the attack that a person may be bitten several times before realizing the snake is there.

Of the 166 bite victims, 139 (84%) showed clinical evidence of envenoming: local signs were trivial, but the majority developed hemostatic disorders and neurotoxicity. the murine SC LD50 value is 0.21 mg/kg,[7] making it one of the most venomous true cobra species (genus Naja) in the world.
