Some can Humayun.. It all depends on the ferocity of the bite however. A death adder can strike without injecting any venom, a warning if you. Inland Taipans can strike without extending their fangs.. so essentially a warning also.. These situations are rare however...
Provided your jeans are fairly loose fitting you SHOULD be ok... I would go for wearing hiking boots that come up above the ankle.. Most strikes on humans occur to the feet/ankes. and a good pair of leather upper hiking boots should provide adequate protection... Couple that with the superior sense of sight and situational awareness that us humans are lucky to have, and you should have no worries at all...
Ric n Dave, I couldn't think of a better name for something that is going to be 12~15 long and covered in scales... My pets all have strange names like that...
3x Bearded dragons - Bubbles, Squeek and Bob (bob is a big male, he bob his head a lot... seemed fitting)
1x 7yo NT locale BHP - Fluffy.
1x 2yo Jungle python - Yowie (Thats what I end up saying every time Im near her... She Bites..)
1x Green Tree Snake (not to be confused with Green Tree Python) - Grey.
1x Inland Taipan - Nikita (Did you ever see that show "La Femme Nikita" ? That chick was great to look at, lightning fast and could kill you in seconds given the chance and motive... Much like the Taipan..
