[QUOTE="Nicolas C, post: 84931, member: 3795"] As early as spiderlings can hunt, they have venom. As far as I know, the composition of the venom doesn't change between a spiderling and a grown up. As the others have said, what changes is the size of the fangs (when tiny, the spider has no ability to perforate the human epidermis, but with tarantulas, this ability comes rather early because of the size of the fangs) and the amount of venom available. As venom is stored in the chelicerae (in tarantula's case), the bigger the size the more the available quantity. In other words: yes, your Haplopelma has venom, yes it's the same as a grown up, but maybe (?) it's still too little to perforate your skin and the quantity is less than an adult. In any case, you should be very prudent! One more thing: it's always difficult to know how effective tarantula venom can be for a human being, because a tarantula can choose the amount of venom it injects. Sometimes there's no venom at all, only the mechanical bite (= dry bite), sometimes there's more venom, sometimes and sometimes it injects the maximum venom available. [/QUOTE]
