|Male Tarantula at Henry Coe State Park|
The tarantulas found in this region are not dangerous. They have large fangs used for hunting, but are not poisonous to humans. Their demeanor is timid, and passive toward larger animals. If possible they will stay hidden and out of sight. The best policy toward any wild creature is to observe at a reasonable distance, but to simply leave them alone, and not stress them out. The best chance you will have to spot one is when they decide to use the hiking trails. Many wild creatures will often use the easiest path to get somewhere, and tarantulas are no different. They will be nearly impossible to spot in high grass or foliage. The biggest concern I always have is that they don’t get run over by cyclists. So if you ride a mountain bike in the Diablos in fall, please remember to look out for them. They are fascinating creatures, and play an important role in the ecosystem.
