Spinnerets produce silk in which group?

Spinnerets produce silk in which group?

• A. Insects
• B. Amphibians
• C. Spiders
• D. Crustaceans

Answer: (C)

Spinnerets are the silk-spinning organs of spiders. Located at the back end, they connect to silk glands inside the abdomen. Silk proteins are secreted as a liquid and pulled through tiny spigots on the spinnerets, producing strong, adjustable fibers used for webs, egg sacs, and lines of safety. This specialized mechanism is characteristic of spiders among the groups listed; amphibians and crustaceans don’t produce silk, and while some insects make silk, they use different glands and structures rather than spinnerets. So the group is spiders.
