DESCRIPTION
Doing a lamprey dissection is an incredible, hands-on learning opportunity for students!
These fascinating creatures resemble eels and are characterized by a toothed, funnel-like sucking mouth. Sea lampreys are jawless fish, as are deep-sea scavenger fish called hagfish.
This plain preserved lamprey specimen is 18"-28" in length. Lampreys are vertebrates of the class Cephalaspidomorphi, and the genus of this dissection specimen is typically Petromyzon (Atlantic) or Entosphenus (Pacific).
During a lamprey dissection, students can learn to find and identify different parts of a lamprey's:
- respiratory system: respiratory tube, pharynx, buccal funnel, lungs, papillae, etc.
- nervous system: spinal cord, notochord, etc.
- cardiovascular system: heart, aorta, anterior cardinal vein, ventricles, etc.
- endocrine system: pineal gland, pituitary gland, etc.
- digestive system: intestines, cloaca, etc.
- reproductive system: gonad (the organ that produces the ovary/testis), etc.
- external anatomy: eyes, nostrils, external gills, anterior dorsal fin, posterior dorsal fin, caudal fin, etc.
- and more!
Much can be learned when studying the side of the head and body of a lamprey, and even more can be discovered when you explore its complex body systems from a ventral point of view during a lamprey dissection!
10+ pricing is based on bulk-packed specimens. When necessary, you will receive a combination of 10-packs and individually packed specimens to fill your order.
Note: Specimens are initially preserved with a formaldehyde solution, the best animal tissue fixative. The formaldehyde is then displaced first with water and finally with a glycol solution to produce a moist, low-fume specimen which will not decay over time.
