====Variations====
  * Consider doing a virtual dissection instead.
  * Compare the anatomy of stingrays with sharks, which share many features as cartilaginous fish.
  * Contrast stingray anatomy with that of bony fish to highlight evolutionary differences.
  * Create a labeled diagram of external and internal structures.



====Safety Precautions====
  * Gloves and lab coats required.
  * Be aware that stingrays typically have venomous tail barbs; ensure they are removed prior to dissection.
  * Handle dissection tools with care to avoid injury.
  * Dispose of biological waste properly and disinfect tools and trays after use.
  * Wash hands thoroughly at the end of the lab.




====Questions to Consider====
  * What adaptations help stingrays move efficiently in the water? (Flattened body and large fins for gliding.)
  * How do spiracles benefit stingrays compared to other fish? (They allow water intake even when the stingray is resting on the ocean floor.)
  * What role does the stingray’s liver play beyond digestion? (It aids buoyancy in addition to producing digestive enzymes.)
  * How is the circulatory system of a stingray different from that of mammals? (It has a four-chambered heart designed for aquatic respiration rather than a double-loop system.)
  * Why are stingrays classified as cartilaginous fish? (Their skeleton is made of cartilage, not bone.)
