  1. The Good, Bad, and OK

    Posted by Mr. Bob on Dec 13th 2022

    As a long time customer, I have always found the specimens to be a good value for the students to explore the structures of various specimens. This is the second time I purchased this group of 7 large specimens for classes. The first set we great, but not so this go round. The "good' were the frogs, perches, and crickets. They were nice size, fresh, and the preservative odor was not unbearable when dissecting. The same cannot be said for the crayfish and the starfish. These specimens were good size, but the meat was rotten and the preservative odor made students nauseated. The really bad were the giant clams. When I open the bag, my face began to tingle immediately and within 15 minutes...the world was spinning as we battled trying to pry open the specimens to cut the muscles! We endured about 30 minutes before students started asking to sit or get fresh air...and I too became overwhelmed by the fumes. The "OK" were the worms. Their lil bodies prevented careful careful tool use from piercing the intestine underneath, however, the "business end" was of adequate size and so I considered them acceptable for examination. The next time I need specimens I will reconsider this affordable kit and probably "a-la-cart" instead.

  2. Great Purchase

    My middle school students enjoyed the various organisms that was purchased as many of them have never touched or seen a preserved specimen. We will be using your products again next year for more dissections and examples in our Life Science Curriculum.


  3. Great Value

    Posted by Shanna on Apr 19th 2021

    My 8 yr old was thrilled to get his box of critters to dissect after his 13 yr old sister dissected at school. So far he’s dissected the worm, grasshopper, starfish and frog. All were in perfect condition and well preserved. I was pleasantly surprised they don’t smell nearly as bad as the animals I dissected that had been preserved in formaldehyde. He took the remaining animals to specimens to his homeschool group and all were excited about seeing them. It’s a great value for all we got! I’d definitely purchase more for future science experiments from here.
