The large spiders of the Valley Hohr are a peculiar and unique species upon Barsoom. They are web weaving spiders, they hang upon these webs from twelve legs that grow upward from their back and are entirely dependent upon the web for transportation, upon the ground their legs are entirely useless and the spider helpless. The spider is evidently a predator it has large fangs indicating it is possibly venomous. Even if it is not it lets out a loud shriek disproportionately loud compared to the creatures size, this sound summons hordes of these tiny creatures, thus even if their fangs are not filled with poison it is doubtful that any prey could survive an attack by thousands of these creatures.
