Lamprey Dissection || Once Bitten, Twice Shy

Have you ever wondered how a lamprey’s mouth works? Learn how to dissect a lamprey in this video, which also covers its external and internal anatomy and physiology. In this simple dissection of a lamprey, you’ll learn various parts of its anatomy, why lampreys have teeth on their tongues, and how lampreys eat.


Lampreys are a very interesting animal because they’re a proto-vertebrate, and their anatomy shares a lot of similarities and differences with later vertebrates. Their wicked mouth and odd gill slits are fascinating to learn about! Also, did you know that lampreys don’t have a stomach? In this video, you’ll learn general information about lampreys, which will be tied into its anatomical structures.


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


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

Eyes Ventral branch

External nostril Esophagus

External gill slits Intestine

Dorsal fin (anterior and posterior) Gills

Anus Internal gill slits

Cloaca Heart

Mouth Liver

Papillae Gonads
