This set of nine medium-sized preserved animal specimens includes a fetal pig (7-9"+), grass frog (3"+), earthworm (6-8"), Lubber grasshopper, crayfish (3-4"), clam (3-4"), perch (5-7"), starfish (3-5"), and Grantia (sponge). None of these specimens are injected with colored latex. Good for high school dissection labs. Packaged together in one bag.
Specimen quality in this set is usually higher than the average quality of our 7-piece set. The sizes we receive from our supplier are frequently a bit larger than the sizes indicated, although we cannot guarantee the larger size.
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. Plan to use specimens within one year of purchase to ensure the best tissue quality. Specimen discoloration and dryness over time is normal and does not indicate decay.
Store your specimens at normal room temperature—refrigeration is not required. Storage in attics or garages at high temperatures will damage the specimens. Once opened, specimens can be resealed in a zip-lock bag to prevent them from drying out for later use.
Crayfish specimen will include at least one cheliped to dissect; although, in some cases, it may be detached from the body.
Shipping Note: This item contains preserved specimens and only ships to a street address in the 50 US states.
