Scorpion Dissection || A Scorpion Under Every Stone

Did you know that scorpions are arachnids, not insects? Learn how to dissect a scorpion in this video, which also covers its external anatomy and physiology. In this simple dissection of a scorpion, you’ll learn various parts of its anatomy, how sea anemones eat, and why it’s an arachnid, not an insect. Unfortunately, most preserved scorpions are too small to observe the internal structures without a dissecting microscope, so we’ll only cover the external anatomy in this video.

Scorpions are a very interesting animal to examine because they share many characteristics with arachnids, such as eight legs! Also, did you know that scorpions glow under UV light? In this video, you’ll learn general information about scorpions, which will be tied into its anatomical structures.

This dissection lab is for anyone who is curious about scorpion anatomy, wants to cover scorpion anatomy for a zoology course, missed the scorpion dissection during biology class, or just wondered, “Is that an insect?”. The video will teach you how to dissect a scorpion step by step, and review the external and internal anatomy of the scorpion.

In this video, we’ll cover the following structures:

Exoskeleton Telson (venom deposit)

Chitin Stinger (aculeus)

Tagmata Medial eyes

Head (Cephalothorax) Lateral eyes

Abdomen Chelicerae

Pre-abdomen Gnathobases

Post-abdomen Sternum
