Smithsonian® Prehistoric Sea Monsters™ Kit is rated 2.6 out of 5 by 5.
Rated 3 out of 5 by from Fun for the first day! I bought this product for my 8 year old son. He couldn't wait till we opened and set up on his desk. It took two days and night to hatch. It was so exciting for us to see tiny little creature are swimming and getting bigger. However, some reasons water started getting dirty and even mold started growing around the food my son put it in. Maybe because the hot days we had that week, I tried to scooped dirty parts but 3 days later they all died and my son was so sad. It was fun that week, but I wish he could kept them longer. It's worth to try again!

Rated 4 out of 5 by from Really works! Our little troops are swimming around! The matter that the eggs come packed in makes the tank look very dirty. Also, there is NO info about how or where to get more food. I went on the Smithsonian site and found nothing...

Rated 4 out of 5 by from Sea Monster Kit I purchased this kit for my daughter, and it has two hatchings included. The first time, we followed the directions exactly, and used distilled water. I washed the sand provided in the kit by adding water, and decanting the liquid. There were lots of small sand particles that we got rid of until the added water was crystal clear. We left it under a light continuously during the hatching process both times. The first hatching resulted in many freshwater shrimp that resembled brine shrimp, and a single Triop. While the shrimp hatch quickly, it took the Triop significantly longer to hatch, so be patient. Wow is it odd looking!! My daughter was so excited, we finally relented and allowed her to take it to school to show to her class. We used a Mason jar for transport however, not the provided tank. The second hatching we used a Mason jar with some aquarium sand at the bottom. This hatching also resulted in many shrimp, and also a single Triop. So the kit worked for us both times, but the hatching efficiency is low. When the Triops are small, crushed food pellets are good, but when they get bigger, carrot bits are best. My daughter spent hours watching her Triops and learned a great deal about these organisms.

Rated 1 out of 5 by from Out of Stock Online- Good I bought the Smithsonian Prehistoric Seamonsters for a Christmas gift for my son from Michaels. We followed the instructions verbatim, even went out and spent more money to get the distilled water. Every day we checked to "hatch and grow your own prehistoric pets" and every day, nothing. We have waited an extra week prior to writing this review, just in case, and still nothing. Don't waste your time or the emotion of your disappointed child, not worth it.

Rated 1 out of 5 by from No seamonsters We purchased this for our son for Christmas and we've waited 3 weeks and still no creatures. We have only seen a couple grass sprouts developed.
