Tarantula fang (Chelicere) @6,2x

The chelicerae are one of the most powerful body parts of the theraphosid. Ventrally on the chelicerae are the fangs, these hollow hypodermic needle-like structures are what deliver venom into prey or attackers. Situated prolaterally on the chelicerae are the cheliceral teeth. The cheliceral teeth aid in helping the spider crush its food. Strikers situated retrolaterally on the chelicerae (Image: ) form half of the primary stridulating organ, which is rubbed against paddle setae on the maxillae to produce sound.… Check the Anatomy Poster for the rest of the text:
