Chelicerae in spiders are often modified into fangs that perform what function?

Correct Answer: tearing flesh
courtship display
chewing
inject venom

Explanation: Chelicerae are mostly used for feeding, but in spiders, these are often modified into fangs that inject venom into their prey before feeding (Figure 28.43). Members of this subphylum have an open circulatory system with a heart that pumps blood into the hemocoel. Aquatic species have gills, whereas terrestrial species have either trachea or book lungs for gaseous exchange.
