Venomous bites have the potential to be life-threatening and must be taken seriously until proven otherwise, either through a positive ID of the animal being non-venomous, or confirming that the attack was a ‘dry bite’.
Dry bites are bites by venomous animals where no venom was released (i.e. a bite without envenomation). It’s actually quite common in some species. For example, 80% of the time, Australian eastern brown snakes (Pseudonaja textilis) inflict dry bites [1]. By comparison taipans inflict dry bites only 5% of the time [2]
In practice, determining whether or not the bite was a dry-bite is extremely challenging. That’s why we always treat bites as venomous in the bush just in case.
