Crayfish Specimen, 4"-6", Plain

This large freshwater crayfish (also called crawfish) plain preserved specimen is commonly used to study Arthropod anatomy. Genus and species is typically Procambarus clarkii. All crayfish specimen will include at least one cheliped to dissect; although, in some cases, it may be detached from the body.  

Quantity pricing for 10+ 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.
