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
Teeth Olfactory bulb
Pharynx Spinal cord
Dorsal branch Notochord
